ADVANCED SUBSTRATE TECHNOLOGIES

AST develops a method that combines waste from biogas plants and the need for fungal substrates. The method entails that the utilization of energy potential in biogas plants can be increased from the current approx. The method includes facilities for optimized utilization of partially degassed biomass for the production of growth media for fungal production, phosphorus fertilizers and increased bioenergy. The concept uses partially degassed biomass for the production of fungal substrates. The a... bility of the fungi to degrade cellulose, hemi-cellulose and the like in biomass is used to ensure increased and efficient utilization of the total energy potential of the biomass. The use of AST mushroom substrate in pill form will, unlike conventional substrate, be stockfast, easier to handle and provide significantly improved working environment during production as well as be cheaper to manufacture. The plant concept consists of a number of well-known technologies composed in a new and innovative way, ensuring the highest possible energy recycling. AST production unit can be implemented as an addition to a biogas plant or fungus production plant. The AST solution is based on applied patents relating to methods for treatment and utilization of organic matter and biomass in a single plant concept. The concept includes anaerobic fermentation (fermentation without oxygen) followed by separation of degassed biomass with fiber fraction production. After drying and conditioning, the fiber fraction is the basic raw material for the production of substrate for the cultivation of fungi. After fungal cultivation, the spent substrate can be recycled as biomass for the production of biogas.More
