Anaerobic digestion (AD) is a well-established technique for the production of renewable energy (biogas) and the management of organic wastes such as sewage sludge, manures and crop wastes. However, many digester designs still incorporate heating elements within the tank itself (or in the floor or the walls), an outdated design which causes a number of…

HRS Heat Exchangers has welcomed the recent publication of two recent papers by the European Biogas Association (EBA) which highlight the importance of digestate in the overall sustainability profile of anaerobic digestion and biogas energy. HRS has long argued that if biogas energy is to fulfil its potential, then the benefits of using digestate as…

The current world political situation has highlighted the need to reduce our reliance on imported natural gas, and the key role that anaerobic digestion and biogas can play in these ambitions, as well as the importance of domestically produced organic biofertiliser in maintaining food production.
