What is biogas?
Biogas is NOT A FOSSIL FUEL - it is produced by anaerobic fermentation of residual waste from livestock (dung, manure and uneaten food), food industry byproducts (fruit and vegetable scraps residues meat, fish and dairy, brewery waste, food waste and much more), industrial effluent from waste water treatment plants, or agriculturally-cultivated geenleaf biomass.
With the construction of biogas plants, agriculture plays an important contribution to the supply of energy from renewable sources and the disposal of organic waste. The digestate product from the cycle of biogas can be used as high quality fertilizer that closes the agronomic cycle.
Biogas is produced by anaerobic digestion of organic materials in a Sealed Fermenter. This fermenter transforms organic materials into biogas using Methane-producing Bacteria through a complex biological process at about 38-55 °C. More than half of the resulting gas is Methane (CH4); the rest is Carbon Dioxide (CO2).
As much as the CO2 produced is NOT derived from mined or pumped-out hydrocarbons, deposited underground, it produces no CO2-FOOTPRINT thus Bio-Methane is conditionally considered a CLEAN FUEL. The CO2 produced is a valuable feedstock which could be combined with hydrogen and used in numerous productions of valuable hydrocarbons as fuels, polymers, medicines, fertilizers, paints, fibers, etc.
The anaerobic digestion process can be divided into three different types depending on the operating temperatures:
Psychrophilic: 15-30 °C > long-term, low gas yield, sensitive fermentation process,
Mesophilic: 30-45 °C > medium-term good gas yield,
Thermopylic: 45-60 °C > short-lived, very good performance of gas production.
Biogas advantages
-Energy derived from non-fossil natural and renewable sources
-Production of green electricity and thermal energy
-Possibility of access to incentives (tax breaks, green certificates, energy sales, energy saving)
-Reduction of atmospheric emissions of CO2
-Use of digestate as fertilizer of high quality
-Nitrogen removal from sewage
-Perfect integration in the agronomic cycle
The technology applied by our company allows to cover all power requirements with modularity in digesters (single or multiple), producing biogas exclusively from renewable sources.
Types of plants are being offered, which use urban organic waste (F.O.R.S.U.), agricultural waste (manure, slurry), animal waste products and crops ( corn, rice, straw, green biomass, etc.).
The system featuring anaerobic plants is the result of a continuous technological evolution, which has the aim to manage in the best way substrates with complexed biologically characteristics and physically heterogeneous, in order to obtain the maximum yields.
The key element is represented by the extreme flexibility in the management of the biomass in the fermentation step which, through a centralized pumping station, allows to transfer it from one tank to another at any time, so as to obtain a biologically stable and flexible process .
The primary and secondary digesters are designed to have very efficient mixing characteristics with extremely low consumption, hindering in this way the inert deposits on the bottom, and allowing to manage with high precision the temperature of the digestate in mesophilic or thermophilic mode.
The loading phase of liquid and solid biomass is designed with the aim to obtain a pumpable mixture to be introduced into the system directly to the central pumping station and then sorted to the digesters.
The plus of our system
From project to construction
PILOT TESTS WITH VARIOUS MIXTURES OF PRODUCTS
We offer design, realization, management and control services for plants, with customized solutions aimed at maximizing efficiency at the lowest costs possible. Dependability is the product of experience and of accurate verification of variables. This is why pilot tests are the pillar and guarantee of success for the project.
We use a laboratory for pilot testing and feasibility studies, also in the field. It also performs:
Fermentation tests,
Analyses of the quality of the various substrates,
Verification of the digestate and any treatments required.
