ReFood steps on the gas.
The process by which biomass is converted into biogas in the absence of oxygen occurs naturally in moorland habitats, for example. The organic material used in ReFood biogas plants, however, consists of biological waste such as food waste or the contents of fat separators.
Inside the biogas plant’s fermenter, microorganisms initially split the complex carbohydrates, proteins and fats into simple organic compounds like sugars or fatty acids by means of hydrolysis. Environmental variables such as temperature and pH are important factors. Millions of bacteria convert these intermediate products into acetic acid and then into biogas, which comprises more than 65 per cent methane gas depending on the quality of the fermented substrate. The methane gas is then used in combined heat and power (CHP) plants to produce electricity and heat.
Bioenergy for a green future
ReFood provides customers in industry, the retail trade and restaurant chains with a safe processing method by fermenting food and kitchen waste in its biogas plants. Converting methane gas into electricity also makes a significant contribution to protecting the environment and conserving resources. Even the fermentation product itself becomes a high-quality, organic fertiliser for agricultural use after processing.
ReFood is well placed to meet future requirements in the energy market. Other environmentally friendly biogas plants are at the planning stage in Germany, France and the UK or are already under construction. ReFood demonstrates farsightedness both as a reliable waste disposal and processing partner and as a producer of dependable renewable energy.
