Anya Cheng - Taelor
About the GuestAnya Cheng is the founder and CEO of Taelor, a Silicon Valley–based men’s clothing rental service that pairs professional stylists with AI and turns customer feedback into insight for fashion brands. Before co-founding Taelor with Phoebe Tan, Anya spent around 15 years building digital products for some of the world’s largest consumer companies. At Meta she helped build Facebook and Instagram Shopping. At eBay she was head of product, launching new businesses across the US, Latin America, Africa and Asia. As head of product at Target she helped open its Silicon Valley tech office, and as a senior director at McDonald’s she was in charge of everything digital, from in-store ordering kiosks and digital menu boards to the drive-thru, the mobile app and food delivery. Originally from Taiwan, Anya has grown Taelor to more than 100 brand partners, partnerships with the New York Yankees and Coffee Meets Bagel, and recognition in Inc.’s 2025 Best in Business awards.Episode SummaryWhat if the most valuable thing a clothing company could collect wasn’t the sale at the till, but what happens after you get dressed? That question sits at the centre of Taelor. In this episode of Shape the System, host Vincent Turner talks with founder and CEO Anya Cheng about a men’s clothing rental service that doubles as a data engine for the fashion industry, and why the two halves of the business make each other stronger.Anya’s starting point was personal. Leading large teams at Meta, and feeling like an imposter, she wanted to dress in a way that projected confidence. She had no interest in fashion itself. Subscription boxes required her to buy from every shipment, and rental sites asked her to scroll through tens of thousands of garments. That led to her realisation: most fashion companies are designed for people who love fashion, not for people who simply want to be ready for their day.The consumer offer is simple. For around US$100 a month, members receive six garments chosen by AI and professional stylists. They wear them, send them back without washing them, and receive the next lot, so there’s no shopping and no laundry. What members give back is feedback, and because Taelor knows who they are and where they wore each outfit, that feedback comes with context. It might be a founder heading to a conference, a Boston lawyer on a date night, or a man whose size medium now sits an inch short at the belly.That context is the gap Anya sees in today’s AI. Models know what people review, click and buy online, but almost nothing about what happens in the physical world once the parcel arrives. The fashion industry badly needs that knowledge. By Anya’s figures, around 40% of most brands’ inventory goes unsold. That’s roughly US$300 billion of stock in a US$1.8 trillion market, in an industry she says accounts for around 10% of global carbon emissions. The main cause is that brands forecast next year’s demand from last year’s sales. Taelor’s feedback is specific enough to act on: the second button falls off after five washes, or the fabric doesn’t stretch enough for bigger, active American customers. Anya contrasts that with the one-star “too big” reviews she saw as head of product at Target, which never said which size, which body shape or after how many washes. She says brands using Taelor’s data have seen sell-through improve by around 20%.The brand stories show how this works in practice. A Los Angeles label that had only ever sold through wholesale found out which hoodie fabric was its real hit, and began using it across its range. FINE, a Taiwanese manufacturer that produces for global athletic brands, launched its own label in the US. It learned that its single-material, easily recyclable fabric wasn’t stretchy enough for the market, and it changed course. Dutch brand R2 Amsterdam faced new European rules against destroying unsold stock, so it used Taelor to rent that inventory to American customers and test a new market at the same time. Many of these suppliers have since become customers of Taelor’s AI agent, which lets them query benchmark data across brands without needing an engineer.Vincent draws out a theme that runs through the whole conversation: the gap between what the customer is buying and what the system achieves. Taelor’s members aren’t paying for sustainability. They want to close the deal, win the job or land the second date. One member wore a dolphin-print shirt to a conference and found it opened conversations. Another reluctantly wore a blazer to dinner, and it ended up around his date’s shoulders on a chilly walk home. Anya describes Taelor as the gadget guy behind the superhero. Yet the model quietly delivers environmental outcomes. Like an airport rental car fleet, garments are sold before they wear out, on average after about three rentals and at around 50% off, through dynamic pricing. Inc. highlighted exactly this when recognising Ta

Ari Kimmelfeld - Commonplace
About the GuestAri Kimmelfeld is the founder and CEO of Commonplace, a New York–based marketplace for buying and selling bulky, high-value secondhand goods (fitness equipment, hot tubs, appliances, furniture and more) with inspection, payments, delivery and warranties built in. A lifelong secondhand shopper who was buying and selling snacks at summer camp at the age of eight, Ari studied accounting before joining a management consulting firm. There he first did due diligence on businesses that private equity firms were looking to buy, then spent most of his time helping Fortune 100 companies build corporate-backed ventures across product, engineering and go-to-market. Commonplace began during the pandemic as a two-button website for secondhand Pelotons. In under three years it has grown into a managed marketplace with more than 3,000 trained drivers across the United States.Episode SummaryEveryone has a Facebook Marketplace horror story. Commonplace has a sign in its office asking people to share theirs, and the team takes it out onto the street to collect them. In this episode of Shape the System, host Vincent Turner speaks with founder and CEO Ari Kimmelfeld about why buying and selling big secondhand items is still so painful. They also cover what it takes to make a used fridge or hot tub as easy to buy as a new one.The idea grew out of a pandemic-era glut. Locked-down Americans bought Pelotons in droves, and once gyms reopened many of those bikes became very expensive clothes racks. Ari is a keen cyclist. He bought one secondhand, took a cab to collect it, hauled it down five or six flights of stairs, and got it home with the resistance broken. He saw an opening and put up a website called Trade My Spin with exactly two buttons: buy a Peloton, sell a Peloton. Google picked it up, and tens of thousands of sellers from across the US submitted bikes. The business sold them for US$499, roughly 75% off retail, with delivery, a warranty, and the shoes, mat and weights included. Ari isn’t a developer. He admits the stripped-back first version was born of necessity, but it worked because the demand was already there.Ari is clear about where existing platforms succeed and where they fall short. Local marketplaces like Craigslist and Facebook Marketplace work well in big cities with deep inventory. Shipping-based platforms like eBay suit smaller items such as collectibles or podcast gear. Both break down over long distances, with physically large goods, and when an item’s value is high but the buyer can’t inspect it first. The consequences are real. A seller might pay a few hundred dollars for junk removal on a fridge, or US$600–700 just to move a hot tub, even when the item has most of its working life left. Meanwhile, buyers face cash-only deals, no financing, no warranty and the job of organising movers themselves. As Ari puts it, there’s simply no “connecting the dots” between someone’s unwanted fridge and the person about to buy one new.Commonplace’s answer is to rebuild the experience of buying new, layer by layer, around used goods. All payments run through the platform. Buyers reserve an item for US$1 and pay nothing until it’s delivered and installed. Before pickup, sellers refresh their photos, videos and description for the buyer to approve. A driver then carries out a 30–50-point inspection on collection, and the buyer can even FaceTime in to watch. If the item doesn’t match the listing, it stays put and the buyer isn’t charged. Drivers complete category-specific training courses and quizzes, and they unlock more technical categories, such as connecting a hot tub’s electrics, as they upskill. Every purchase comes with a free two-month parts warranty, and there’s an optional 12-month parts-and-labour warranty for big-ticket items. For hot tubs, Commonplace has even layered in the electrician, plumber and concrete pad that a new-tub dealer would arrange. Buyers save around 65% off retail on average.The economics are simple. Sellers pay a 20% fee in about 95% of categories, rising to 30% for jobs like swim spas that need a crane. Delivery is free within 100 miles (about 160 km), and nationwide shipping is available, with a treadmill from New York to Los Angeles costing around US$1,100. Add-on revenue comes from accessories, warranties, a “Store to Sell” service that collects items from people who are moving within 48 hours and sells them later, and paid promotion that pushes listings out to other platforms. Sellers also set a floor price up front, and any offer above it is accepted automatically, which ends the endless back-and-forth of “is this still available?”. On growth, Ari’s approach is to show up wherever buyers already shop. Vincent compares it to Airbnb’s early days on Craigslist. Gyms and med spas have started listing equipment, but the focus remains on peer-to-peer consumer sales, with Canada next, then Europe, then Australia.Th

Chris DeArmitt - Plastics Research Council
About the Guest Dr. Chris DeArmitt FIMMM FRSC CChem is an independent polymer scientist, author, and founder of the Plastics Research Council — a nonprofit where he and professors from around the world work entirely unpaid to review and share peer-reviewed science on plastics. A specialist in polymer additives and fillers whose clients have included Apple and companies across multiple continents, Chris has spent over seven years and roughly a thousand hours annually reading thousands of studies on plastics, the environment, and human health. His findings are published in two freely available books and endorsed by toxicologists, medical doctors, and professors who have checked the science and found no errors. Episode Summary What do you actually know about plastics — and where did that knowledge come from? That's the question Dr. Chris DeArmitt puts to every audience he speaks to, and the answer is almost always the same: the media. In this episode of Shape the System, host Vincent Turner sits down with Chris for a wide-ranging, evidence-first conversation about one of the most misunderstood materials on the planet. The result is an episode that will challenge most of what you think you know — not through opinion, but through peer-reviewed science. Chris opens by reframing the scale of the problem. Plastics represent just half a percent of all materials and waste we produce. Replacing them with paper, metal, or glass would require roughly double the fossil fuel — not less — because those alternatives demand far more energy to manufacture. And despite the ubiquitous image of a turtle tangled in a plastic bag, Chris recounts successfully pushing the BBC to retract a photoshopped image of exactly that scenario, which he argues has never occurred in nature. The famous "floating island of plastic the size of Texas"? Undetectable by satellite, and contradicted by decades of ocean monitoring data showing a vessel must sail 100,000 miles — four times around the planet — to find a single piece of plastic bag. On microplastics, Chris is equally direct. Our lifetime ingestion of plastic particles amounts to roughly 0.015 grams over 70 years — a hundred million times below the no-observable-adverse-effect level established in over 2,000 studies spanning 60 years. The WWF's claim that we eat a credit card's worth of plastic each week, he notes, has been refuted by multiple independent studies — and remains on their website regardless. Meanwhile, the most common end-of-life options for plastic — landfill, incineration for energy recovery, or mechanical recycling — are all scientifically defensible, with recycling reducing environmental impact by a further 70% on top of plastic's already lowest-in-class baseline across 93% of applications studied. Looking forward, Chris draws a clear line between innovations with evidence and those without. Plant-based versions of existing polymers like polyethylene and polypropylene — chemically identical to their fossil fuel counterparts, recyclable in the same streams, with decades of safety data — represent a credible path. Novel biopolymers like PLA, PHA, and seaweed-derived plastics, by contrast, lack life cycle evidence that they reduce environmental impact, regardless of how appealing they sound. The most unsexy innovation he highlights may also be the most significant: down-gauging, the continuous industry-wide effort to use less material to do the same job. A PET bottle that weighed 25 grams a generation ago now weighs around 8 grams — a 60% reduction in material, achieved quietly, without a press release. Key Takeaways Plastics account for just 0.5% of materials and waste, and replacing them with paper, metal, or glass would roughly double fossil fuel usage — making plastic bans scientifically counterproductive by every life cycle study ever conducted. Our lifetime ingestion of microplastic particles is approximately 0.015 grams — a hundred million times below the established safe threshold — and no study in 60 years of research has documented a health effect from plastic particles at real-world doses. Plastic has the lowest environmental impact in 93% of applications studied, even without recycling; adding recycling reduces that impact by a further 70%, but the material is already net-positive before any recycling takes place. Litter is caused by litterers, not manufacturers — scientific studies comparing tourist beaches to remote beaches confirm litter originates from people on the beach, and post-bag-ban studies in Maine, Washington State, and New Jersey all found increased environmental impact and increased plastic sales following the bans. Plant-based polyethylene and polypropylene exist today and are identical in performance and recyclability to fossil fuel-derived versions — a more cr

Carly Hunt - Showerkap
About the Guest Carly Hunt is the Head of Strategic Partnerships of Showerkap, a UK-based water technology company tackling excessive water consumption in the hospitality sector. With over 20 years in hotel management — latterly focused on energy, waste, and water reduction programmes — Carly brings rare operational depth to the sustainability challenge she's now helping to solve. Her academic background in sustainable tourism (the subject of her university dissertation) makes her return to this space something of a full-circle moment. Episode Summary Water scarcity might not be the first thing that comes to mind when you book a hotel room, but it probably should be. In this episode of Shape the System, host Vincent Turner sits down with Carly Hunt, Head of Strategic Partnerships of Showerkap, to explore how the hospitality industry is one of the heaviest — and least scrutinised — consumers of fresh water on the planet. Hotels can use up to eight times more water than local residents, with individual rooms consuming as much as 1,500 litres per day. Meanwhile, the UK's Environment Agency is forecasting a potential shortfall of 1.4 billion litres per day by 2030, rising to 5 billion by 2050. The numbers are stark, and Carly makes the case that demand reduction — not just supply management — has to be part of the answer. Carly's entry into this space came through two decades of hotel management, where she discovered that energy and waste were relatively easy to monitor and reduce, but water was almost impossible to measure at any meaningful resolution. That gap led her to Showerkap, the brainchild of inventor Steve Harding, which combines three elements that have never previously been integrated in the water sector: fixture-level IoT monitoring across an entire building, a cloud-based analytics platform, and a novel shower fade timer that delivers a real-time behavioural nudge — without restricting flow. The pilot results, run across one floor of the Sandman Hotel at Gatwick Airport, were striking. Prior to the intervention, guests were showering for 35 minutes or more — consuming around 245 litres per session. After the shower fade timer was introduced (set to seven minutes), average shower duration across the 20-room eco-floor dropped to just three minutes and 20 seconds. Overall water usage fell by 58%, energy use by 14%, and the projected saving across the full hotel is approximately 2.7 million litres per year. Of the guests who stayed across nearly a year of the pilot, only three declined to participate in the eco-floor — a participation rate that Carly and Vincent calculate at roughly 99%. The commercial case is deliberately straightforward: Showerkap is targeting a two-year payback period, meaning hotels can effectively finance the installation against the savings it generates. Beyond the headline water and energy savings, the technology surfaces hidden operational value — the Sandman pilot uncovered hot water circulation issues throughout the building and enabled early detection of Legionella risk. The go-to-market strategy currently leans on pilots and case studies to build trust in a space where water has historically been undervalued, with an eye toward expansion into the Mediterranean, MENA, and other water-scarce markets. An upcoming back-of-house research piece, potentially in partnership with the Sustainable Hospitality Alliance, is expected to extend Showerkap's evidence base well beyond the bathroom. Key Takeaways Hotels use up to eight times more water per person than local residents, with some rooms consuming up to 1,500 litres per day — making demand reduction in hospitality a high-leverage intervention. Showerkap's pilot at the Sandman Hotel, Gatwick, achieved a 58% reduction in shower water usage and cut energy consumption by 14%, with average shower times dropping from 35+ minutes to under three and a half minutes. The technology's payback period is approximately two years, making it financeable against projected savings — a critical threshold for hotel procurement teams weighing up an unfamiliar category. Behavioural nudges, not flow restrictions, drive the results: the shower fade timer gives guests a gentle cue and the option to continue, yet the vast majority choose to reduce — suggesting most water waste is habitual rather than intentional. Showers account for over 50% of hotel bathroom water use, but the IoT platform also surfaces back-of-house inefficiencies in kitchens, laundry, and plumbing systems — unlocking operational and maintenance savings beyond the guest experience. Notable Quotes "Water is one of the most vital resources on earth. And we all know that. And we rarely treat it that way because we automatically run a tap and it's there." — Carly Hunt

Lewis Dunnigan - Bygen
About the Guest Lewis Dunnigan is the CEO and co-founder of Bygen, an Australian deep-tech company reimagining how activated carbon is produced. Lewis came to the problem through his PhD research at the University of Adelaide, where he and his team recognised the commercial potential of their work and spun out the company. He brings both the scientific depth of an academic researcher and the commercial pragmatism of a founder who has already shipped product to customers on multiple continents. Episode Summary Activated carbon is one of the most widely used industrial materials on the planet — and one of the least talked about. It filters your drinking water, treats industrial gas emissions, recovers gold from ore, remediates contaminated land, and even plays a role in pharmaceutical processing and energy storage. In this episode of Shape the System, host Vincent Turner sits down with Lewis Dunnigan, CEO of Bygen, to unpack what activated carbon actually is, why the way it's currently made is both costly and environmentally damaging, and how Bygen's production technology is changing the equation. At its core, activated carbon is a highly porous solid material — visually indistinguishable from barbecue charcoal — but with a surface area so vast that a single teaspoon contains the equivalent of a football field. That porosity is what makes it such a powerful filtration medium: contaminants in liquids and gases are physically attracted to and trapped by the densely bonded carbon atoms inside. The problem is that making it the conventional way requires heating raw materials to around 1,000 degrees Celsius using fossil fuels like LPG or diesel — a process that is both expensive and carbon-intensive. The two dominant global feedstocks, coal and coconut shell, each carry their own environmental and social baggage. Bygen's core innovation integrates the two-stage production process — charcoal production and activation — into a single system that generates excess heat rather than consuming it. By combining both steps and developing alternative activation chemistries that operate at lower temperatures, Bygen has effectively eliminated the largest operating cost in conventional activated carbon manufacturing: the external energy input. The result is a cleaner, cheaper production process that uses sustainable feedstocks — including almond, walnut, and hazelnut shells, as well as wood — sourced locally to wherever the plant is built. Bygen already has a plant running on walnut shells in Northern California, and a truck was loading activated carbon for a water treatment plant during the recording of this episode. The company operates a licensing model, partnering with feedstock owners — such as large nut-processing or cracking facilities — who gain a way to convert a low-value byproduct (selling for perhaps $30–40 per tonne as cattle feed) into a high-value product worth around $4,000 per tonne. For end users like water treatment plants, Bygen competes not on price against cheap Chinese coal-based imports, but on quality, reliability, and service. The North Star is 200,000 tonnes of activated carbon produced annually using Bygen's technology — roughly 5% of the current global market of around 4 million tonnes per year — requiring five new project deployments per year and approximately 1 million tonnes of feedstock. The next 12 months are focused on building the team and capital base to make that deployment rate a reality. Key Takeaways One teaspoon of activated carbon contains the surface area of a football field — that extraordinary porosity is what makes it effective at trapping contaminants in water, gases, and industrial processes across a huge range of industries. Conventional activated carbon production burns fossil fuels at 1,000°C, making it both expensive and carbon-intensive; Bygen's integrated process generates excess heat rather than requiring external fuel, cutting the major cost driver and eliminating associated emissions. Bygen's licensing model locates plants at the source of feedstock — nut-cracking facilities, forestry byproduct sites — turning a low-value waste stream worth ~$30–40/tonne into an activated carbon product worth ~$4,000/tonne. The global activated carbon market is approximately 4 million tonnes per year, with Bygen targeting 5% of that (200,000 tonnes) via five plant deployments annually across the US, Europe, and Southeast Asia. Australia currently sends almost all spent activated carbon to landfill — unlike the US and Europe where regeneration (restoring used carbon to a near-virgin state) is standard — a gap Bygen is actively working to close. Notable Quotes "Despite these great use cases, the way that it's been made for the last hundred plus years is very, very ha

Jason Rolland - Carbon Inc
About the GuestJason Rolland is the CEO of Carbon Inc, a leading additive manufacturing company focused on production-grade 3D printing. Trained as a polymer chemist, Jason completed his PhD at the University of North Carolina at Chapel Hill under Carbon co-founder Joe DeSimone, where he developed a deep interest in translating materials science into real-world impact. His career sits at the intersection of chemistry, entrepreneurship, and advanced manufacturing, with a particular focus on making 3D printing viable for end-use products at scale. At Carbon, he has helped shift the industry from “rapid prototyping” to true digital manufacturing.Episode SummaryIn this episode of Shape the System, host Vincent Turner sits down with Jason Rolland to unpack how additive manufacturing—specifically polymer-based 3D printing—is reshaping the way physical products are designed, made, and distributed. Rather than framing 3D printing as a novelty or prototyping tool, the conversation explores its emergence as a genuine manufacturing alternative to injection moulding and foams.Jason walks through the limitations of traditional manufacturing, particularly where cost efficiency comes at the expense of performance, customisation, and waste. Using examples from footwear, helmets, bike saddles, wheelchair cushions, and dental products, he explains how lattice geometries and advanced elastomers unlock new performance characteristics—such as targeted cushioning, breathability, and durability—that simply aren’t possible with conventional methods.The discussion also touches on broader system-level implications: on-demand production, reduced tooling, faster iteration cycles, and more localised manufacturing. From Adidas’ fully 3D-printed Climacool shoe to millions of custom dental parts produced each month, the episode highlights where the economics already work—and where they’re heading next.Key Takeaways3D printing is moving from prototyping into true manufacturing, producing end-use parts that match or outperform traditional materials.Lattice structures enable performance gains—variable stiffness, breathability, and impact protection—that foams and injection-moulded parts can’t achieve.Customisation at scale is already real in sectors like dentistry, with millions of unique parts produced every month.Digital manufacturing reduces reliance on tooling, enabling faster design iteration and lower inventory risk.The biggest barriers to adoption today are awareness and application development speed, not material performance.Notable Quotes“It’s no longer okay for something to be cool just because it’s 3D printed. It actually has to serve function and do something better.” — Jason Rolland“Nobody actually cares about all the cool tech that’s behind it. They care about the part that comes out of the printer.” — Jason Rolland“You can intrinsically have stiffer regions and softer regions within the same part just by changing the geometry.” — Jason Rolland“The success of the year isn’t how many shoes you sell—it’s how much inventory you have left over.” — Jason Rolland“There’s almost no industry that can’t benefit from what we’re doing.” — Jason RollandResourcesCarbon Inc — https://carbon3d.com/?utm_source=shapethesystem.org Shape the System is an independent podcast with support from KPMG High Growth Ventures More about KPMG High Growth VenturesScale up for success.

Mike Haydon - Off the Grid Shop
About the GuestMike Haydon is the CEO of Off The Grid Shop, a business focused on solar, batteries, and decentralised energy solutions. With more than 15 years in the renewable energy sector, Mike has built his career around the idea of energy sovereignty—helping households and businesses stay powered, resilient, and in control. His background spans off-grid systems, peer-to-peer energy trading, and software-driven energy orchestration. Today, he’s working to rebalance who benefits from Australia’s energy transition.Episode SummaryIn this episode of Shape the System, host Vincent Turner sits down with Mike Haydon to unpack a deceptively simple question: do we still need electricity grids? The answer, as Mike explains, isn’t about abandoning the grid—but rethinking how it’s used, who it serves, and who captures the value created by rooftop solar and batteries.Mike shares his journey from early solar installations to building a decentralised energy model that lets everyday households sell excess energy directly to businesses. The conversation explores why feed-in tariffs have failed consumers, how smart meters and software are reshaping energy markets, and why rooftop solar is already Australia’s largest generation source during the day.The discussion also looks ahead. From peer-to-peer trading and carbon credits to blockchain-ready meters and the rise of energy “orchestration,” Mike outlines where the next three to five years are heading. Throughout, a clear theme emerges: the future of energy isn’t just hardware—it’s software, transparency, and communication.Key TakeawaysRooftop solar is already the number one generation source in Australia during the middle of the day, but households see little financial upside.Energy retailers can resell household solar at 50–60× the price they pay consumers.Businesses that use most of their power before 5pm can save 20–30% by shifting to decentralised and wholesale energy models.Smart meters, with five-minute interval data, are a critical enabler of peer-to-peer energy trading.Long-term winners in energy will be those who master software, data, and customer communication, not just generation assets.Notable Quotes“For us, it was never about feed-in tariffs. It was always about energy sovereignty.” — Mike Haydon“Rooftop solar, in the middle of the day, is the number one generation source in Australia.” — Mike Haydon“Energy security and being connected to the grid aren’t opposites—they can coexist.” — Vincent Turner“The energy retailers are making all the profit from assets they didn’t pay for.” — Mike Haydon“The biggest opportunity is control and flow of energy—it’s orchestration.” — Mike HaydonResourcesOff The Grid Shop — https://www.theoffgridshop.com.au/?utm_source=shapethesystem.org Shape the System is an independent podcast with support from KPMG High Growth Ventures More about KPMG High Growth VenturesScale up for success.

Johan Tijssen - Hempblock
About the GuestJohan Tijssen is the CEO of Hempblock International and a long-time builder and entrepreneur with more than 25 years’ experience working with hemp-lime (hempcrete) construction systems. Originally from the Netherlands, Johan moved to Australia and became deeply interested in why modern housing had become so complex, fragile, and uncomfortable. Through years of hands-on building, experimentation, and R&D, he developed an interlocking hemp block system designed to simplify construction while dramatically improving thermal comfort, fire resistance, and durability. Today, Johan works with owner-builders, architects, and developers globally to rethink how walls—and homes—are built.Episode SummaryIn this episode of Shape the System, host Vincent Turner speaks with Johan Tijssen about what’s fundamentally broken in the way we build houses—and why walls are at the centre of the problem. Johan contrasts today’s lightweight, multi-trade wall systems with thicker, simpler, and more durable approaches used historically, arguing that modern construction has traded long-term performance for short-term speed and perceived cost savings.Johan shares his personal journey from traditional building into hemp-based construction, after discovering hempcrete’s unique properties: insulation, fire resistance, breathability, and longevity. From there, he explains how Hempblock International evolved the material into a modular, interlocking block system that removes on-site mixing, reduces trade complexity, and enables faster, more accessible builds—even for owner-builders.The conversation explores the practical realities of construction economics, labour shortages, bushfire risk, and health issues like mould and humidity. Johan also outlines a bigger vision: scaling hemp construction into social housing, large developments, and even Olympic-scale projects, while regenerating soil and sequestering carbon through industrial hemp farming.Key TakeawaysModern wall systems rely on multiple materials and trades, increasing cost, coordination risk, and long-term failure points.Hemp block walls deliver R-values up to 4.8, over 3 hours fire resistance, and natural humidity regulation in a single system.The interlocking hemp block approach allows walls to be built at roughly 10 minutes per square metre, with minimal specialised skills.Hemp-lime walls petrify over time, improving durability rather than degrading like many petrochemical-based materials.Scaling hemp construction could support carbon-negative housing, healthier indoor environments, and regeneration of polluted soils.Notable Quotes“Walls are really like a complex system… and they require lots of different trades and moving parts.” — Johan Tijssen“I was totally fascinated by the fact that this one wall thickness would do everything—insulate, fireproof, and perform over time.” — Johan Tijssen“You’d be with a sledgehammer for half an hour before you get a hole in a hempcrete wall.” — Johan Tijssen“Hemp and lime petrify over time. There are no petrochemicals that break down.” — Johan Tijssen“The success is when people love where they live and feel safe, healthy, and comfortable in their own homes.” — Johan TijssenResourcesHempblock International — https://hempblockinternational.com/?utm_source=shapethesystem.org Shape the System is an independent podcast with support from KPMG High Growth VenturesMore about KPMG High Growth VenturesScale up for success.
