What we do

WE TRANSFORM ORGANIC WASTE INTO BIOGAS
 
 

CIRCULAR ECONOMY

We transform waste into energy and biofertilizer, closing the natural cycles, taking advantage of all the components of the waste for the generation of new food. Our plants meet the highest industry standards to achieve our purpose.

Waste valorization

We valorize energetically household and industrial organic waste through anaerobic digestion.

 

With this technology we are able to transform the organic matter contained in organic waste into energy in different forms, such as electrical energy, thermal energy or biogas, which is a biofuel with characteristics similar to natural gas.

 

Biofertilizer Production

We supply the digestate to various farmers in the vicinity of the site areas as a biofertilizer and/or soil improver for agricultural use.

 

It is done by incorporating the material into the soil, an application that makes the micro and macronutrients contained in the digestate available to the vegetation for its use, thus promoting the circular economy together with sustainable agriculture.

Energy production

Through anaerobic digestion, we transform the chemical energy contained in organic waste (organic matter) into a biofuel called biogas.

It consists mainly of methane (CH4), which is a component containing the chemical energy transformed into a gas.

BIOGAS

Biogas is a biofuel that is generated as a result of the decomposition of various organic substances in oxygen-deprived conditions by a large number of bacteria. 

The energy contained in the chemical bonds is released and stored mainly in methane (CH4), which together with carbon dioxide (CO2) is the main component of the biogas generated. The other substances, present in lower percentages, are carbon monoxide, nitrogen, hydrogen and hydrogen sulfide.

* Anaerobic processes, like many other biological systems, have a variety of relevant parameters, for example, they are strongly dependent on temperature, pH, the nature of the substrates, among others.

ANAEROBIC REACTORS

The bacteria involved in this process, called methanogenic bacteria, is very sensitive to pH variations, so the optimum conditions for the process to develop are at a stable pH of around 7.0-7.2. Low pH values reduce the activity of methanogenic microorganisms, causing the accumulation of acetic acid and H2. As the partial pressure of H2 increases, propionic acid degrading bacteria will be severely inhibited, causing an excessive accumulation of high molecular weight volatile fatty acids, particularly propionic and butyric acids, which will decrease the production of acetic acid, leading to a decrease in pH. If the situation is not corrected, the process will eventually fail.

The biochemical characteristics of these wastes must allow the development and microbial activity of the anaerobic system. The microbiological process requires not only carbon and nitrogen sources, but also mineral salts such as sulfur, phosphorus, potassium, calcium, magnesium, iron, manganese, molybdenum, zinc, cobalt, selenium, tungsten, nickel and other minor salts.

There are several ways to obtain biogas, there is the capture through wells drilled up to 30 meters deep in landfills, landfills or similar. And it can also be obtained through anaerobic digestion reactors, finding in these a variety of technologies.
