BIOGAS solutions

Transforming waste into valuable energy.

In today’s world, industries are under increasing pressure to adopt sustainable solutions that minimize environmental impact and optimize resource use.

One of the most promising solutions is the production of biogas from wastewater – a process that not only reduces environmental impact but also creates a valuable energy resource.

What is biogas?

Biogas is a mixture of gases produced during the breakdown of organic matter in the absence of oxygen.

It can be generated from: agricultural waste, sewage sludge, food waste, municipal and green waste.

It primarily consists of: methane (CH4) (50–75%) and carbon dioxide (CO2) (25–50%), with trace amounts of other gases like hydrogen sulfide (H2S) which can be toxic, corrosive, and dangerous to both health and equipment.

How is biogas used?

Methane, the main component of biogas, is a potent energy source that can be used for electricity and heat generation, direct heating applications, and even as a vehicle fuel.

Biogas is commonly used in: wastewater treatment plants, organic waste digestion facilities, landfills, where gas is collected and utilized.

The concentration of hydrogen sulphide in biogas can vary from 250 ppmv up to several volume percentages; it has an offensive odour of “rotten eggs” at concentrations as low as 50 ppbv and is toxic at concentrations above 100 ppmv.

At some applications H2S must be removed before the biogas can be given for utilization, for reasons of health, safety, environment and due to the fact that hydrogen sulphide gas is corrosive and can damage equipment like gas engines, boilers, piping, etc.

Desulphurization of the biogas is also required when biogas is upgraded to natural gas quality for injection into the gas grid
