Low maintenance and wear and tear on plant components.No, or little mechanical pre-treatment of the biomass is necessary.Robust, innovative technology with low maintenance and downtimesĪdvantages compared to the wet digestion systems include:.Absolutely insensitive to impurities and contaminants (e.g.Designed for biomass with high solid and dry content.This is regarded as the new generation of biogas technology. Upcycles low-grade organic waste into a high-value energy sourceĭry Anaerobic Digestion with a Biogas Digester has proven to be the optimal technology for the utilization of these organic residues and wastes, which are predominantly available worldwide in a solid and stable form.This is a solution for two of the largest and most difficult to decarbonize sectors of transportation (mobility) and the natural gas grid (regional energy supply).

Methane is 25 times more potent than the greenhouse gas CO2, which is considered the main driver of global warming.īiogas being upgraded (cleanse impurities, separate CO2 from CH4) to Renewable Natural Gas (RNG) is to the natural gas grid as wind and solar are to the electricity grid. In its production, Biogas is emission-neutral and avoids climate-damaging methane emissions from landfills. Organic residues and waste, from the municipal collection (organic waste, green waste), from animal husbandry and breeding, as well as agriculture and arable farming, from the food industry and gastronomy, become clean, renewable energy, valuable organic fertilizer, and compost for healthy soils. Today’s raw material sources are green in the sense that they are renewable and carbon-neutral.
Waste incineration and landfill are representative of the globally prevailing linear economic system and contradict the principle of sustainability. Biomass is probably the most underestimated natural and never-ending resource in the world. The increasing substitution of fossil fuels, such as natural gas, by biogas, would dramatically improve the climate balance. Digestate can be a source of revenue or cost-saving. With appropriate treatment, the digestate can be used in many useful applications, as a nutrient-rich fertilizer, as an organically enriched compost, or simply as a soil improvement, in which case the farm can use it as a fertilizer on the fields. This can be sold and injected into the natural gas distribution system, compressed and used as vehicle fuel, or further processed to produce alternative fuels, energy products, or other advanced biochemicals and bioproducts.ĭigestate is the leftover material after the digestion process. Also, biogas can also be purified by removing the inert or low-value components (CO2, water, H2S, etc.) to produce renewable natural gas ( RNG). Like natural gas, the energy contained in biogas can be used to generate heat and electricity. Outputs from Biogas Digester: Biogas and Digestateīiogas consists of a relatively high percentage (50-75%) of methane (CH4), the main component of natural gas, as well as carbon dioxide (CO2), hydrogen sulfide (H2S), water vapor, and traces of other gases. Co-digestion can increase biogas production from low-yielding or difficult-to-digest organic waste. Co-Digested substrates include manure, food waste, or crop residues. Several types of organic materials (feedstocks) can be mixed together in one digester. These digester tanks contain complex bacterial cultures that break down (digest) the waste to produce biogas and digestate, which is the end product of the Anaerobic Digestion (AD) process. Anaerobic Digestion in a Biogas Digester is the process in which bacteria biodegrade organic materials – such as solid animal manure, bio waste, and food waste – in the absence of oxygen (o2).īiogas production in a Biogas Digester is done in gas-sealed units called digesters, which are designed and built in different forms and sizes depending on the types of feedstock and loading amount.
