Over 25 years of biogas from waste – processing and fermentation for waste of every kind
BTA recognised early on that separating waste as fully as possible into different fractions and processing these appropriately are prerequisites for the sustainable, economically viable treatment of waste. This is why, since 1984, BTA has spent a total of eight years developing and optimising the BTA® process, which combines the hydromechanical treatment of waste with the anaerobic fermentation of organic fractions in a pilot plant.
Benefits of the BTA® process:
- flexible adjustment to biological, municipal, food and industrial waste
- high operating safety and low costs due to elimination of foreign materials before fermentation
- maximum biogas yield owing to the defibration and concentration of more than 90% of the degradable biomass as suspended organic matter
- valuable synergies for disposal and incineration thanks to the reliable elimination of organic material from light and heavy-weight fractions
- possibility of producing high-quality, marketable compost.
Foreign materials, such as plastics, film, wood, stone and metal, are eliminated in the BTA® Waste Pulper in one single step using process water. Organic material is dissolved and reduced to fibre, and forms a valuable suspension. Any remaining settleable inert material in the suspension (sand, glass splinters) is reliably separated in the BTA® Grit Removal System.
As a result, the fermenter content can be fully mixed by biogas recirculation without the need for moving parts, ensuring low maintenance requirements and high operational reliability. The BTA® process is unique in the efficiency of its foreign material separation and safe fermentation.
BTA International has 40 reference plants worldwide and 25 years of experience in the entire waste-to-biogas process chain. We offer reliable components and complete plants for the mechanical and biological treatment of waste (MBT), industrial and organic waste, and waste processing in water treatment plants.
