Bulrush paludiculture: a new cash crop for rewetted peatland
British materials company Ponda is working to make bulrush commercially valuable enough that farmers will flood their fields again rather than drain them. Its product, BioPuff, is a plant-based insulation spun from bulrush fiber and sold as an alternative to goose down and petroleum-based synthetic fill. Ponda recently secured a £2.35 million grant from the United Kingdom's Department for Environment, Food and Rural Affairs to scale production, underwriting a 30-hectare site and a 30-month project to grow bulrush on rewetted peatland alongside J&K Barnard Farms, Liverpool John Moores University, the Lancashire Wildlife Trust, and the outdoor label Berghaus. The approach is part of a practice known as paludiculture — growing food and fiber on wet peat instead of draining it — which keeps land in production while halting the carbon release caused by drained farming. Peatlands cover about 3% of Earth's land surface but store more than 500 gigatons of carbon, according to peatland scientist Franziska Tanneberger of the Greifswald Mire Centre. Stella McCartney has padded her Falabella bag with BioPuff and in October 2025 presented a plant-based feather technique at her spring-summer 2026 show in Paris.
Biobased polymers outperform polyolefins in tensile strength
A research group led by Professor Kotohiro Nomura at Tokyo Metropolitan University, working with the Osaka Research Institute of Industrial Science and Technology and the University of Shiga Prefecture, has developed biobased poly(ester amide)s derived from inedible bio-renewables that exhibit superior mechanical properties in film form compared with commodity plastics such as polyethylene and polypropylene. The polymers are made from non-edible vegetable oils, amino acids, and sugars using olefin metathesis polymerization, and can be converted back into starting monomers through transesterification reactions for chemical recycling, while also displaying self-healing properties at ambient temperature.
Engineered microbes programmed to seek and break down microplastics
Synthetic biologists based in Cambridge have engineered living cells that swim toward microplastics and break them down, building on a 2016 discovery of a bacterium capable of digesting polyethylene terephthalate. The new research uses chemotaxis — rewiring cells to sense the chemical signature of plastic particles and move toward them — while enhancing the degradative enzymes the microbes produce. The work remains confined to the laboratory, and its authors frame it as a proof of concept rather than an imminent remediation tool. Environmental scientists have long argued that prevention, not cleanup, is the decisive lever on plastic pollution, and international negotiations on a treaty to curb plastic production remain contentious.
Food-waste recycling cuts climate impact but risks soil plastic accumulation
Diverting US household and commercial food scraps from landfills to composting and anaerobic digestion could cut the climate impact of US food-waste management by an estimated 89–99% compared with current landfill-dominant practices, according to a US-wide integrated mass-balance and life-cycle assessment published in Nature Food. The same study found that organics recycling could lower associated nitrogen loading to downstream waterways by roughly 49–54% and phosphorus loading by 78–98%, though land-applied composts and digestates would offset less than 2% of annual US mineral nitrogen and phosphorus fertilizer consumption. The authors warn that, without redesigning food packaging, the system could release about 20,000 tonnes of plastic per year into US agricultural soils, creating a long-term accumulation risk for persistent polymers that escape pre-treatment sorting. The study is by Porterfield, K.K., Schambura, M.N. and Roy, E.D.
