Sustainable Construction Materials

Mexico made plastic from cactus — and it disappears like a leaf in the dirt In a small lab in Guadalajara, surrounded by desert succulents and the sharp scent of green nopal, Mexican chemical engineer Sandra Pascoe Ortiz has done something that could rewrite the future of packaging. She has created plastic — not from oil, but from cactus juice. And when it’s tossed into the soil, it vanishes like a fallen leaf in the rain. The key ingredient? The common prickly pear cactus, known as “nopal” in Mexico — a plant so abundant it’s found in gardens, fields, even on dinner plates. Ortiz’s breakthrough lies in extracting the viscous, sticky juice from its thick green pads and turning it into a polymer film that mimics the flexibility and strength of plastic — without any of the toxins or environmental cost. What sets this cactus plastic apart isn’t just that it’s plant-based — it’s how fast it disappears. In regular garden soil, it biodegrades in just 2 to 3 months. In water, it dissolves in less than a week. No microplastics. No residues. No landfill centuries. The material is also edible and non-toxic, making it safe for wildlife and ocean life alike — a vital factor in a planet drowning in plastic waste. Even more impressive, the process doesn’t harm the cactus. Only mature leaves are trimmed, allowing the plant to regenerate naturally. The juice is mixed with glycerin, natural waxes, and proteins, then poured into molds and dried — no synthetic chemicals, no industrial waste. It’s low-energy, low-cost, and perfectly tailored to the arid Mexican climate. Today, Ortiz’s cactus plastic is being prototyped for use in bags, packaging, and even edible wrappers. In rural markets and coastal towns where plastic pollution is devastating ecosystems, the cactus could become more than a crop — it could be the future of circular design. Mexico’s deserts may have just handed us the solution to a global crisis — one green paddle at a time. #invention #design #renovation

A Mexican company called BioFase has developed biodegradable cutlery and straws made from avocado seeds, and they can fully break down within just 240 days. Using discarded avocado pits from food processors, BioFase transforms what would otherwise be waste into durable utensils that perform like plastic but leave no toxic trace. Whether used for hot soup or iced drinks, these items are heat-resistant, sturdy, and completely compostable. Mexico, as the world’s leading avocado producer, generates an abundance of raw material for this innovation, making it both sustainable and locally sourced. It’s a brilliant example of how agricultural waste can become a planet-friendly resource, proving that big impact sometimes starts with small seeds.

What makes of an LCA following EN 15804, an Environmental Product Declaration #EPD? In a single word: ✨VERIFICATION✨ As per ISO 14025 for Type III EPDs, verification must include "𝘐𝘯𝘥𝘦𝘱𝘦𝘯𝘥𝘦𝘯𝘵 𝘷𝘦𝘳𝘪𝘧𝘪𝘤𝘢𝘵𝘪𝘰𝘯 𝘰𝘧 𝘥𝘢𝘵𝘢 𝘧𝘳𝘰𝘮 𝘓𝘊𝘈, 𝘓𝘊𝘐 𝘢𝘯𝘥 𝘪𝘯𝘧𝘰𝘳𝘮𝘢𝘵𝘪𝘰𝘯 𝘮𝘰𝘥𝘶𝘭𝘦𝘴..." So, in addition to following ISO 21930 or EN 15804 for #construction products in Europe and being compliant with specific Product Category Rules, a real EPD must be verified. However, there is a new trend among certain Program Operators: allowing the publication of results without verifying the LCA model, the inventory data, or the LCA results. Yes, you read that correctly. Some POs are allowing workflows in which manufacturers or LCA practitioners can add process areas to underlying LCA models, input and manipulate activity data such as energy and materials consumption, estimate the results, and create an ‘EPD’. Why? The most common answer: scalability and flexibility. But is it okay to scale up a system that produces documents that are supposed to be verified without, or just with partial verification? On the flexibility side, few software are more flexible than SimaPro, OpenLCA or Brightway, and yet, I haven’t seen anyone exporting results from them and calling it an EPD without going through the verification step. Now the good news: - Many EPD tools and LCA consultants I have talked to agree we need harmonised rules among POs on how to deal with these situations, including EPD tools verification. We have the ECO Platform AISBL, the best community for finding consensus in the EPD industry, where these issues are starting to gain some traction. - But probably the most relevant: The new Construction Product Regulation #CPR is here. That means soon there will be an initial plant inspection where manufacturers will (likely) need to show and prove some of their activity data. But more importantly, manufacturers will be liable for the values reported for ‘carbon footprint’ and other environmental characteristics. I cannot imagine a company risking being dragged to court for intentionally or unintentionally tampering with data. The harmonized standards and rules will also apply across the EU and its Notified Bodies. That means there are good chances of saying goodbye to green-shopping, where some companies try to find a way around to have or offer fast EPDs at the expense of skipping the verification protocols. The advantages of all this❓ A fair playing field for everyone: - manufacturers, LCA practitioners, EPD tool providers, - architects and builders able to fully trust the numbers in the Declarations of Performance and Conformity, and - Residents of the EU will be given less uncertain values about the energy and environmental performance of the buildings in which they live and work.

8-Step Process for Setting Science-Based Targets 🌎 The eight-step method provides a clear pathway for organizations to align their sustainability efforts with planetary boundaries. Rooted in scientific principles, this framework enables companies to assess their environmental impact and establish targets that contribute to systemic change. The first step involves defining the sustainability objective by identifying the specific environmental challenges a company aims to address, such as climate change, freshwater conservation, or biodiversity protection. Next, relevant environmental systems connected to the organization’s goals are identified, acknowledging the interconnectedness of planetary processes and operational impacts. Understanding system dynamics follows, where companies analyze how their activities influence key ecological tipping points, ensuring that non-linear impacts are thoroughly assessed. Once system interactions are understood, boundaries and safe operating spaces are established. These boundaries are informed by scientific data and contextualized for specific geographical or sectoral factors, providing a clear framework for operational limits. Companies then map their operations and activities across the entire value chain, adopting either territorial or economic approaches to capture the full scope of their impact. Quantifying associated environmental flows, such as greenhouse gas emissions, water usage, and material consumption, is the next step. This data informs the assessment of impacts, linking flows to specific locations and contextual boundaries. Impact assessments determine how much of the safe operating space is occupied, enabling companies to prioritize interventions and mitigate high-risk activities. The final step allocates impacts within the defined operating space. This involves negotiation and collaboration among stakeholders to distribute responsibilities equitably. Companies can adopt sectoral benchmarks or zero-impact targets to guide their efforts, ensuring that collective actions remain within planetary limits. This framework emphasizes a systemic approach, combining scientific rigor and stakeholder collaboration to drive sustainable business transformation.

Mealworms + Styrofoam = Chitofoam! Ever heard of mealworms eating Styrofoam and transforming it into bioplastic? It may sound like a wacky science experiment, but design studio Doppelgänger has turned this idea into reality with their innovation: Chitofoam. This shock-absorbent, water-resistant bioplastic is made from the exoskeletons of Styrofoam-eating mealworms—and it breaks down in just weeks. It's a promising solution for Styrofoam waste, which clogs nearly 30% of landfill space due to the costly and complex recycling process. Traditional Styrofoam, or expanded polystyrene (EPS), is petroleum-based and loaded with carcinogenic chemicals, making it a long-lasting environmental pollutant. Doppelgänger's designers, Charlotte Böhning and Mary Lempres, looked to nature for answers and found a surprising one. Mealworms, equipped with a unique enzyme in their gut, can actually digest Styrofoam, safely breaking it down. When mealworms complete their life cycle, their chitin-rich exoskeletons can be harvested to produce Chitofoam. This provides the strength and durability of Styrofoam without the toxic footprint. The science behind this process is fascinating. Mealworms naturally shed their exoskeletons in a cycle known as ecdysis, triggered by a hormone that allows them to grow a new protective layer while discarding the old one. Discarded exoskeletons, rich in chitin, become the raw material for Chitofoam, directly connecting to the natural cycles Doppelgänger aims to emulate. Though still in development, the potential applications are vast, from sustainable packaging to fully compostable cups. Böhning and Lempres are actively working on ways to scale production, hoping that Chitofoam could soon become part of daily life and reshape our approach to waste. What do you think, could Chitofoam potentially take down Styrofoam for good? Is this just the beginning of nature-powered design? 📷Doppelgänger

Using pineapple leaves to save the planet, here's how you can change what you wear every day. From Waste to Wardrobe! Piñatex, developed by Dr. Carmen Hijosa, an eco-friendly leather alternative is made from pineapple leaf fibers. Here are the key benefits of Piñatex. Ready to embrace sustainable fashion? • Made from agricultural waste (pineapple leaves). • Biodegradable and eco-friendly. • Durable and versatile. • Requires no additional land, water, or pesticides. • Utilizes about 40,000 tonnes of pineapple leaf waste annually. • Each square meter prevents 12kg of CO2 emissions. • Uses 97% less water compared to traditional leather production. The production process involves: • Extracting fibers from pineapple leaves. • Felting them with corn-based polylactic acid (PLA). • Finishing the material with colors and coatings. Major companies like Hugo Boss, Nike, H&M, and Chanel have adopted Piñatex for footwear, clothing, and accessories, but so far only for special limited editions or experimental designs rather than full-scale adoption across their product lines. But this tech is not yet perfect • Not fully biodegradable (95% biodegradable!) due to PLA and polyurethane coatings. • Limited lifespan compared to traditional leather. Ongoing research aims to address these issues and improve sustainability. Step by Step. Changing what we wear has a huge impact: 1. The fashion industry is the second largest consumer of water globally, using about 79 trillion liters of water per year. This massive water usage depletes freshwater and groundwater resources, especially in water-scarce regions. 2. Textile production is responsible for approximately 20% of global industrial water pollution. The wet processing stage, which includes dyeing and finishing fabrics, releases toxic chemicals, heavy metals, and dyes into waterways. 3. This also affects our health! Contaminated water sources can lead to various health issues in local communities, including skin and stomach infections, cancer, and reproductive problems. As we are changing what we wear when using more sustainable materials, we can play a crucial role in reducing environmental impact and promoting circular economy principles in fashion. ♻️ Repost this if you want your network to learn more about sustainable clothes for every day use and how we can create a better planet for all of us!

🌱 Sustainable UX Toolkits & Resources (https://lnkd.in/eT6ZR3qz), a large (!) repository of toolkits, Figma templates, books, case studies, articles on sustainable UX — throughout the entire product design process. Kindly put together by the SUX - The Sustainable UX Network, via Thorsten Jonas. Sustainable UX Database (Notion) https://lnkd.in/eyZjigBx As designers, we often are left wondering how to integrate sustainable practices into our design work. Most environmental impact happens on our user’s devices, so we can help our users by reducing waste. Typically, when we speak about sustainability, we mean at least 4 facets of it: 🌱 Reducing waste ← In publishing, heavy visuals, animation, PDFs, 🌻 Deleting content ← Un-publishing outdated, misleading content/flows, 🐝 Maximize reusability ← UI components, flows, processes, templates, 🌳 Sustainable defaults ← Help people make more sustainable choices. In practice, we could use simple but impactful design patterns: 1. Always prefer the lightest mode of communication. 2. Aim to reduce session duration instead of increasing it. 3. Encourage the reuse of existing templates and presets. 4. Auto-delete after 365 days what hasn’t been used once. 5. Discourage users from PDF exports in favor of URLs. 6. Always provide audio-only and transcript for videos. 7. Be intentional with default settings for your users. 8. Highlight key insights to create understanding faster. 9. Skip unnecessary pages: drive users to results faster. 10. Show filters/presets in autocomplete, not just keywords. 11. Nudge users to delete old files for 10% off that month. 12. Establish an archiving, deletion and clean-up policies. 13. Encourage and reward users for trying out dark mode. 14. Question font weights, stock photos, parallax, 4K-videos. 15. Question collected data, if it’s used and when it’s deleted. Individual actions can drive changes at scale. But they need a momentum. And momentum often comes through small changes: better defaults, reused filters and templates, reduced time on task. That’s also just good usability — and can have tangible impact for users and businesses at scale.
