Gasification is often confused with incineration, although they are totally different processes. Incineration is the actual combustion or burning of solid fuels, which takes place at higher temperatures, combusts the material completely, and does not produce a carbon-rich EcoChar.
Gasification solution
The main component of our gasification solution is our down-draft fixed-bed gasifier. This patented design is generations ahead of wood-fueled systems and is engineered to support a variety of fuels, including manures and other biomass.
The gasification process takes place in the primary unit, in an oxygen-starved environment, thus controlling nitrous oxide (NOx) formation. The low-pressure system allows for gasification with no or minimal carryover of particulate matter from most fuels.
Processing syngas
The main product of gasification is carbon monoxide (CO) with some hydrogen and methane gasses, called synthesis gas (syngas). The syngas composition is fuel dependent, with temperatures typically ranging between 800-850 °C. As soon as the syngas leaves the gasifier and flows into the thermal oxidizer, ambient temperature air is introduced to oxidize the syngas, with the CO being converted to carbon dioxide (CO2). Retention time in the oxidizer is 1.2/2 sec (depending on local legislation). In this process a hot air stream is produced (energy content between 5.5-6.1MWth) of about 1000°C.
Output hot air
The ability to use the thermal energy product as direct heat, steam or electricity is a simple matter of adding equipment. The modular design makes construction quick and easy, and the addition of components is comparatively simple.
Output EcoChar
The solid output of the system is called EcoChar. Temperature control and retention time are critical in the quality of EcoChar, and these factors may vary depending on its application. In our gasifier temperature and retention time can easily be controlled to ensure the required output (for both the carbon monoxide and the quality of the Ecochar).
Web-based remote controlled
The system is web-based remote controlled, allowing off-site operation of the system if desired. This provides tremendous flexibility and oversight to the owner and the ability for real time troubleshooting which can eliminate downtime. The system has PLC controls which can be interfaced to most existing systems, and provides a wide range of flexibility in operating parameters and the ability to control the system to provide the proper amount of energy for the customer’s needs – both when and where they need it.
Other fuels are:
The input of the gasifier is a fuel with the moisture content of maximum 20-30%. If the fuel/input has a higher moisture content a pre-drying step has to be taken. I necessary this pre-drying step will be included in our gasification solution.
Soil improver: EcoChar is valuable for improving stability in soil. EcoChar deposits the carbon and nutrients from the source material back into the ground. Due to the absorbent nature of the char, EcoChar will enrich the soil, but in a form that is not susceptible to nutrient leeching/run-off.
Animal bedding: EcoChar can hold more than its own weight of moisture. EcoChar is highly effective at moisture and ammonia reduction, leading to a more pleasant environment and healthier animals. In poultry houses, weight gain consistently increased due to reduced ammonia and moisture content. An ammonia reduction of 30% was observed when using char in horse stalls.
Animal feed ingredient: EcoChar has a high content of P, K, Ca en Mg.
Water and active coal filtration: The ability of EcoChar to filter and absorb fine particulate makes it perfect for use in removing unwanted contaminants from water sources.
Heavy metal remediation: Research shows that the amount of different metals captured by EcoChar is higher than by an activated carbon product.
Air treatment: Activated carbon is an essential part of most odor filtration devices. EcoChar has been proven to be effective in odor reduction, and is viable as a filter medium. For example, EcoChar proves to be effective in the cleaning out of small pet cages such as guinea pig and rabbit. After the addition of EcoChar to their litter, the need for cleaning was reduced from every two days, to every two weeks.
Economic value EcoChar:
• Increases plant growth and improves performance over time
• Guarantees less ‘soak-away’ from high-quality nutrients
• Lowers the amount of fertilizers and nutrients needed

Our gasification solution can be used to take care of your waste streams and convert them into multiple revenue streams. Each project varies by fuel type, project size, and needs of the host facility. There are multiple value streams applicable that have a positive influence on the economics/ ROI of our gasification system. These are the key to a short payback period. Mavitec Environmental provides economic modeling to help you evaluate your potential projects, and not only solve your waste disposal problem but make it a feasible project.
