The Designer's Compass: Navigating the Sustainable Material Wild West 1 The Designer's Compass - Part 1: The Carbon Equation: Decoding LCA and Tackling Plastic's Waste Crisis 2 The Designer's Compass - Part 2: Threadbare Truths and High-Heat Emissions: Balancing Reuse in Textiles and Metals 3 The Designer's Compass - Part 3: From Forest to Fired Clay: Re-evaluating Renewable and Mineral Resources 4 The Designer's Compass - Part 4: Beyond the Bin: Carbon Capture and Nature's Toolkit for Future Materials ← Series Home Key Takeaways Wood offers negative carbon footprint through carbon sequestration: About half a tree's volume consists of carbon pulled from the atmosphere, often exceeding emissions from processing. Responsible forestry certification is non-negotiable: FSC and PEFC certifications ensure sustainable harvesting, but designers must also verify against the IUCN red list of endangered species. Engineered wood utilizes waste streams but requires formaldehyde scrutiny: NAF (No Added Formaldehyde) materials using alternative binders are essential to minimize toxic VOC emissions. Paper recycling is finite and requires continuous virgin fiber input: Cellulose fibers degrade after 4-6 recycling cycles, necessitating constant renewal of the material pool. Surface finishes and coatings determine end-of-life recyclability: Painted or lacquered wood is not widely recycled or compostable, making water-based coatings the sustainable choice. The Designer’s Compass - Part 3: From Forest to Fired Clay: Re-evaluating Renewable and Mineral Resources Designers often gravitate toward two fundamentally different material origins: resources derived from natural growth and those derived from the earth’s mineral base. Plant-based materials, like wood and paper, draw their appeal from renewability and carbon sequestration. Mineral-based materials, like ceramics and glass, offer unparalleled durability and inertness. Both categories present unique sustainability challenges that designers must navigate. Understanding the supply chain complexity, from forestry practices to high-heat manufacturing, allows designers to make informed choices. ...

The Arithmetic of Decarburization: A Hard Look at the Energy Revolution ← Series Home The Resource Question We’ve established that decarbonizing Austria requires roughly 166 TWh of carbon-free electricity. But how much renewable energy can Austria actually produce within its borders? This question requires careful analysis. There are many ways to define “potential”: Theoretical potential: How much energy is physically available (e.g., total solar radiation) Technical potential: What fraction can be captured with current technology Economic potential: What can be deployed cost-effectively Reduced Technical Potential (RTP): What can realistically be built given all constraints ...
