Using fallen city trees for greener urban building – Springwise

Spotted: According to one study, rural and urban communities across the US lose around 36 million trees every year, whether that’s due to felling, disease, or weather-related damages. Once they’ve fallen or been cut down, the majority of these trees are chipped, burnt, or simply sent to rot in landfill. This represents a huge waste of potential resources and economic opportunity. One startup that’s hoping to change that is Washington-based Cambium Carbon.

Instead of allowing fallen or cut-down trees to go to waste, Cambium partners with local sawmills and other organisations to turn them into Carbon Smart Wood – a high-quality, carbon-negative building material with various purposes, including decking, siding, fencing, millwork, and lumber. To regenerate land and ensure the long-term of America’s forests, the company allocates 15 per cent of its profits to the planting of new trees, targeting historically underserved and low-canopy areas.

Cambium Carbon also tracks all incoming material through its transparent supply chain software, Traece. With the Traece system, end users can also access information on their Carbon Smart Wood manufacturing, as well as helpful data on the carbon impact, which can be used in a company’s climate reporting as they work to meet sustainability goals.

Numerous companies have seen the potential in Cambium, with Carbon Smart Wood already incorporated across various sites like Maryland’s Guinness Brewery, the Patagonia store in Baltimore, and the National Geographic headquarters in Washington. Furniture retailer Room & Board has also used the material to craft unique coffee and side tables.

There are many other innovators making use of wood to create beautiful, eco-friendly products – including a waterproof wood composite for use in bathrooms and another material made from wood waste.

Paper made from fallen leaves

Spotted: The global e-commerce packaging market is expected to reach a total market value of almost $100 billion (around €92 billion) by 2027, a huge increase from the 2020 value of $35 billion (around €32 billion). Many retailers recognise the high environmental costs such a volume of packaging incurs and are actively seeking recyclable, reusable, and compostable alternatives.  

Paper is often considered a better option than plastic, yet some innovators are seeking ways to avoid deforestation by finding alternative sources of cellulose. One of the most successful so far is Valentyn Frechka and his company, Releaf. As a young student in Ukraine, Frechka spent years studying cellulose to find an alternative way of making paper. After testing fallen leaves, he began working on the technology that is now the base for Releaf, an international distributor of paper and paper packaging.  

Releaf paper is made exclusively from collected biowaste and recycled fibre. The new manufacturing process uses 15 times less water than traditional paper production and reduces carbon emissions by 78 per cent. Much of the feedstock for the company’s products comes from urban street cleaning teams.  

After collection, the leaves are cleaned, dried, and then turned into granules for long-term storage. The granules are stable, allowing the company to keep raw materials on hand for steady production cycles. Releaf produces paper ranging in weight from 70 to 300 grammes per square metre, along with a range of wrapping papers, bags, and e-commerce envelopes. Not only does the Releaf process relieve pressure on the world’s forests – it also helps city governments sustainably dispose of biowaste that would otherwise clog street drains and sewage pipes.

Other paper innovations Springwise has spotted recently include a single-use paper cup with integrated lid and a recyclable paper-based alternative to plastic bubble wrap.
