Overview Unavoidable food waste is increasingly becoming a resource instead of a waste stream. Organic material contained within leftover food waste collected from homes, food manufacturing and retail represents a significant sustainable energy source. When treated by anaerobic digestion, it produces a methane rich biogas. Rather than disposing of organic food waste to landfill with the resultant green-house gas emissions, biogas from anaerobic digestion of organics can be used to generate electricity, biomethane and even compressed for vehicle fuel. Food waste presents a number of challenges to treatment technologies; high levels of contamination in the form of plastic, metal and glass packaging along with grit can cause significantly impact digestion plant performance if not handled properly. Plant impacts can range from reduce digester production, plant downtime and additional operational and maintenance costs, all leading to losses in revenue. Benefits The Monsal ADT Re:Sep 2 process offer the following benefits: • Capable of treating waste streams with contamination levels up to 30%, higher when throughput is reduced. • Modular and scalable design capable of treating small or large flows • Produces ideal digestible slurry, easily handled and resulting in maximum conversion into biogas • Capable of treating both liquid and solids waste inputs • Widest range of feed stocks including source segregated food waste, residential, commercial and industrial wastes and organic slurries Active removal of grit and settleable material from produced slurry through integrated hydrocyclone • Greater than 95% organic material capture through the high efficiency separation of organic and contamination streams • Proven robust and long life system

Figure 2: Monsal ADT Re:Sep 2 Process Applications Monsal ADT Re:Sep 2 process can treat a wide range of feed materials from very high dry solids material to slurries and liquids and with contamination levels up to 30% by weight, including: • Source segregated food waste from households • Commercial waste from restaurants & cafeteria • Waste from food manufacturing including packaging • Liquid wastes and slurries • Slaughterhouse waste and many more Improving Food Waste Treatment In order to treat food waste, the associated contamination such as food packaging, bones and inorganic hard particles...
