Anaerobic Digestion

Anaerobic Digestion or AD, is a series of processes whereby microorganisms are used to breakdown organic substances into usable products in a oxygen free environment. Traditionally, AD is carried out on ’wet’ waste such as pig slurry or sewage. It produces useful products such as methane gas which is then used in an engine or turbine to produce electricity. ‘Waste’ heat is recovered from the exhaust of the engine / turbine and used to heat the process as AD works best in a warm environment.

Autoclaves

An autoclave processes waste with the aid of steam, rendering it sterile while reducing its mass volume by up to 60% of the original mass.

This process is also an efficient method of seperation of unsorted waste to aid recycling.

The Ultra Green autoclave system is powered by our waste pyrolysis units. Traditionally, autoclave systems consume significant quantities of energy to power them, and leave residue which has to be disposed of - often to landfill.

Biogasifiers

Gasification is a process that thermally decomposes biomass into its natural gaseous state of hydrogen and carbon utilizing a controlled amount of oxygen. Using carefully calibrated conditions, long-chain molecules are broken down into large quantities of heat and a high energy content combustible gas known as syngas - a combination of carbon dioxide and hydrogen.

Pyrolysis

Pyrolysis is the cornerstone of Ultra Green’s waste to energy capability, providing us with a valuable tool to allow our clients to regain value from their waste in the form of electricity and heat.

Pyrolysis is a technology whereby material is heated in the absence of oxygen to produce a useful syngas consisting of methane, hydrogen and carbon monoxide. As the material is heated in the absence of oxygen, traditional contaminants such as Nitrogen Dioxides, Sulphur Dioxides and dioxins are not produced as the required oxygen molecules are not available.

RAS Systems

Modern sewage plants are normally associated with intricate processes and complicated technology that require skilled labour and equipment. The costs involved in this type of operation can be expensive, especially in remote locations or in areas that cannot afford to provide new outfall sewage pipes to connect communities to the existing waste water treatment plants.
