Gasification is the gasification of non-organic waste and dry biomass, in particular agricultural and forestry residues, to produce syngas by heating at high temperatures. The syngas is processed into green biogas for gas consumption and as a fuel for electricity generation. Each gasification plant operates an average of 8,000 hours per year and processes approximately 7,500 tonnes of waste per year. Converted, depending on the composition of the input, this produces 1.2 to 2 Mwh of electricity per hour.

The green gas produced is a substitute for fossil natural gas and therefore makes a positive contribution to the climate. The positive contribution is optimised because by capturing the CO2 during the production of electricity. The green gas is used to drive generators to generate electricity or it is used as a fuel such as traditional natural gas.

Government, businesses and private individuals are urgently looking for replacements for natural gas. In the long term, hydrogen can take on this role. Green gas can already directly replace natural gas. It has exactly the same combustion properties.

The gasification process is shown schematically as follows:

The process

Upon receipt of the waste and residual flows from agriculture and forestry, drying takes place up to 90% dry matter. The gasification plant can use the lowest quality waste materials, not being recyclables such as glass and metal, as input in all possible sortings. Pollutants can be processed. There is no chimney, but there is an emergency flare to burn gas that does not meet the requirements.

After heating, the raw syngas produces a mixture of carbon monoxide, carbon dioxide, methane and hydrogen. After a cleaning step, the tar components have disappeared. The syngas is stripped of dust particles via filters.

In the next step, the syngas is converted to methane and upgraded to green gas in such a way that it meets the requirements to be offered as a gas to be used. The process also produces additional heat. This heat can be used for heating or drying processes.

In addition to green gas, carbon dioxide (=CO2) is available in pure form. 

In summary, there are four products with a value: hydrogen gas, green gas, CO2 and warmth.

Why our BlueRevo technology:


A new fermentation process has been developed for all non-gasified waste: Hogen Technology This process makes it possible to use residual flows, such as agriculture, horticulture and forestry, and household biomass as co-fermentation material. This makes the process cheaper and raw materials are widely available.

The technology used is aimed at breaking down (hard) cellulose and lignite (the most important components in manure, grasses and wood).

Thanks to a sophisticated mixture of inputs (water, manure and residual flows), Hogen Technology has a higher yield than more traditional digesters. The residue is sold as a fertilizer (bio-fertilizer) for application in agriculture and horticulture.

The process with the ‘Hogen’ technology is as follows: 

Crushing the input to the short fibres with the ‘hydropulper’

Hydrolysis to break open the cellulose membranes

The plug-flow reactor with four separate zones with special bacteria that effectively convert the biomass into biogas

After pressing the residual material, the water returns to the system and the dry matter (completely odourless) can be used as fertiliser

An installation for the processing of 75,000 tons of waste per year at 8,000 production hours results in a converted output of approximately 5 MWh per hour at an average input composition.

In summary, there are four products with a value: green gas, CO2, warmth and BioFertilizer.

Schematically, the process looks like this:


The LeachBuster® is an innovative and state-of-the-art technology that can treat a wide range of high solids waste streams (up to 50% solids) in polluted water without the need for pre-filtration or staging. The system can be tuned to its contents to generate clean water streams with a broad spectrum of purity, depending on the use of recycled water. The LeachBuster® system is also capable of removing heavy metals such as arsenic, selenium and the like from drinking water. Up to 99% of the water can be recovered from most wastewater streams for reuse or back into the environment. The results with the LeachBuster® system exceed government mandates for the treatment of high solid/multiple polluting waste streams such as raw wastewater, industrial wastewater, landfill percolate, digestion plants or animal waste. The system does not use chemicals and the concentrated solids can be processed in various environmentally friendly ways.


    Wastewater transformed into reusable water and resources creates a clean environment and offers economic opportunities

    Because the leach-buster can be used decentrally, on-side, it results in considerable cost savings

    Significant cost savings by reusing treated and recycled water

    Recovered materials are collected for reuse elsewhere

    Preserving nature by conserving water and avoiding new pollutants in our natural resources and communities


CO2 capture and storage (internationally abbreviated to CCS of carbon capture and storage), also known as carbon capture, is the capture and storage of carbon dioxide gas released during the combustion of (fossil) fuels. By capturing and storing the greenhouse gas CO2 resulting from the combustion of these hydrocarbons in reservoirs, this CO2 does not end up in the atmosphere.

The CO2 captured can be used industrially, such as in the oil industry and beverage manufacturers. Below is a sketch of improved oil extraction with CO2 technology.
