Recycling Nature: How Nature’s Byproducts Are Shaping Materials
Every year, agriculture and aquaculture production generate mountains of waste that never make it back into use: rice husks left over from harvests, seashells discarded by the seafood trade, sawdust and offcuts piling up in sawmills. Most of it ends up burned, buried, or forgotten. Left to decompose in landfill conditions, organic waste releases methane, a greenhouse gas more than 25 times more potent than CO2. A new wave of material innovation is proving that this waste isn't waste at all, it's raw potential.
Materials from Natural Waste
Companies are now transforming these agricultural, industrial, and food-industry byproducts into usable, sustainable materials, using processes that produce low-to-zero VOC emissions and avoid the environmental costs of virgin material extraction. Rice husks, for example, are being compressed into durable panels for furniture. Seashells, crushed and mixed with a mineral matrix, are transformed into seastone terrazzo for tabletops, bar fronts, and walls. Sawdust and wood scraps, once destined for landfill, can now be used as a material for 3D printing, enabling the creation of complex organic shapes. In each case, the byproduct gets a second life, cutting production costs while reducing the industry's environmental footprint.
Rice Husk Board
Rice Husk Board
Rice husk board is a material made from locally sourced agricultural residues and rice-milling waste, instead of virgin forest products. As an alternative to traditional MDF, it also helps reduce the open burning of agricultural waste. Production involves low emissions and eco-efficient manufacturing methods.
Rice husk board can be used for furniture, walls, countertops, bar fronts, and more. It can also be machined for custom textures and cuts, or shaped into 3D and sculptural objects.
The material uses a proprietary, natural, bio-based adhesive binder that is completely formaldehyde-free and contains zero volatile organic compounds (VOCs). It's manufactured using 100% renewable energy, with a zero water footprint.
Rice husk board is available in two fire-resistance grades, with the higher-rated version enhanced by blending in mussel shell to achieve a Bs1d0 rating. Both variants are certified for natural biological durability, offering fire-retardant and water-repellent properties, and are highly resistant to termites, woodworm, and fungi.
To recycle the material, no chemical separation is required. At the end of its life, the board can be mechanically shredded and remanufactured into a brand-new board, making it 100% circular.
Recycled Digital Wood
Timber is the most commonly used material in architecture and design, yet it's also one of the largest waste producers, generating significant offcuts and scraps before it ever reaches a final product.
Recycled Digital Wood is a material made from wood residues sourced from offcuts, sawmill waste, and construction or demolition waste. These residues are mixed with a dry, magnesium-based Sorel cement binder and shaped using a 3D printing technique called Selective Cement Activation (SCA), which selectively deposits a saltwater activator onto a bed of the material.
Wherever the saltwater touches, the material hardens into a flame-retardant, solid structure, while the unused loose wood powder can be fully recycled into the next production run, making this a zero-waste production technique.
This additive manufacturing approach opens up new design possibilities, offering the freedom to create almost any shape through digital modelling and generative design exploration.
Seastone Terrazzo
Seastone terrazzo offers a new type of terrazzo made from seashells, oyster, scallop, mussel, and others, combined with a mineral mixture that makes it safe for the environment, unlike traditional terrazzo, which is made with a petroleum-based binder such as epoxy resin. The natural texture and colour of the seashells give unique aesthetic results.
The material can be made into furniture, countertops, bar fronts, and walls. It has very low water absorbency, making it durable and easy to clean.
Recycling seashell waste also reduces the large volumes dumped by the seafood production industry.
Design Without Waste
There are many other sustainable materials that work as alternatives to traditional ones. The push to use recycled natural materials isn't simply about reducing waste, it's also about offering a unique beauty and flexibility that synthetic materials can't provide, with each production run yielding its own unexpected result.
We work with architects and designers to help their work become more sustainable without sacrificing aesthetics or beauty, bringing their vision to life in a way that's more responsible for the environment.
