Waister transforms food waste into biofertiliser, animal feed or biogas booster
- Published 14 December 2022; updated 29 April 2026; estimated reading time 2 minutes. Marked available worldwide; listed under Agritech and food production and Circular economy.
- Waister’s patented dryer uses mechanical fluidisation with air and superheated steam to process wet food waste. The page says it typically reduces waste weight and volume by more than 75%, turning roughly four of five truckloads into a dry, storable and transportable material.
- The dried output is described as usable as biofertiliser, an animal-feed ingredient or a performance booster for biogas plants. Product range is stated for waste volumes from 500 to 10,000 kg/day. Feedstock examples include waste from restaurants, hotels, retailers and food producers; the company also serves aquaculture, fisheries, breweries and other organic-waste producers.
- Waister says the system can reduce disposal costs and emissions associated with transporting or landfilling wet waste. Using dried output as a biogas booster is said to reduce methane emissions compared with landfill or composting. The article gives no independent lifecycle or emissions assessment, and food/feed uses depend on applicable safety and regulatory rules.
- Market context on the page forecasts the global waste-management market at about USD 1.49 billion in 2025 and USD 2.36 billion by 2033, with 6% CAGR from 2026–2033. The article attributes this to a market-research source; these are projections and the figure’s market definition may be narrower than general waste management.
- Linked to SDGs 3 and 12.
