Mechanical disintegration of sewage sludge
Water Science and Technology, 2001 Mechanical disintegration can be used for an accelerated and improved anaerobic digestion of excess sludge. The hydrolysis is the limiting step of this process. Mechanical disintegration can be used to disrupt the cell walls and to cause the release of the organic material from the cells.

PLANTS, PEOPLE, PLANET, EarlyView.The UK's horticultural industry is shifting from reliance on unsustainable peat‐based growing media to products that contain alternative constituents, including coir, bark, wood fibre and composted green waste. Some peat‐alternatives carry an elevated risk of harbouring plant pathogens, including the potential to introduce novel pathogens from overseas,

Process safety at anaerobic digestion sites and its workplace impact: A rapid review
Process Safety Progress, EarlyView.Abstract Anaerobic digestion (AD) is important for the developing green/circular economy and is widely used to process different organic wastes and to capture emitted methane. This greenhouse gas can then be used to generate energy. There are over 700 operational AD facilities across the United Kingdom, excluding water treatment plants, a number ...
