DMG® is the thermal conversion of carbonaceous organic materials – converting complex molecules to simple, safe molecules.

This conversion process evolves in the presence of a managed oxidant combined with the application of intense, indirect thermal energy. When the material is introduced to the DMG® System it almost instantly reduces to EcoSynthesis Gas, a product rich in hydrogen and other commercially desirable chemical precursors.

  1. Materials with high calorific values – e.g. tyres, plastics, woody bio-mass, municipal solid waste, and hospital and hazardous waste – are shredded and then separated into recyclable materials and refuse derived fuel (RDF).
  2. RDF is passed through the purged bin feed system to remove excess air.
  3. RDF moves through the rotating ultra-high temperature thermal conversion chamber at atmospheric pressure in a non-combustive environment. The reactor, operating at above 1,000°C, breaks down the RDF, converting it into EcoSynthesis Gas.
  4. The EcoSynthesis Gas passes out of the reactor and any remaining solid residue, which is safely sequestered and managed is removed and disposed of according to local environmental compliance requirements.
  5. The EcoSynthesis Gas is used both to power the DMG® process and for the creation of targeted end-products. Excess thermal energy generated may be used to heat the site. EcoSynthesis may be converted to chemical precursors, compressed hydrogen, syndiesel or other fossil fuel substitutes suitable for transportation. As EcoSynthesis is broadly analogous to natural gas, it can be used as replacement for heating or use in industrial furnaces.

PowerHouse’s DMG® System works with multiple waste streams, municipal, commercial, and industrial. Ideal target feedstocks include waste plastics and end-of-life tyres. The DMG® System can be configured to accept a variety of feeds: Biomass, mixed plastic wastes, hazardous materials, shredded tyres, or most any other waste not destined to compost or anaerobic digestion.

Purpose-built DMG® Systems are being engineered exclusively for the economical elimination of highly toxic waste in focused arenas like pharmaceutical manufacturing, chemical production, or other industrial applications.

Auto Shredder Residue (“ASR”) is another niche market that is extremely interested in DMG® due to the cost of eliminating the non-recyclable components of automobile dismantling. Our ability to convert the nonrecyclable organic components of the ASR allows us to process those organics into EcoSynthesis, provide power for the operation of the dismantling operations and create useable precursors for newly developed product lines.

The advantages of DMG® are multifold. In addition to a reduced carbon dioxide footprint compared to incineration, our DMG® process results in little to no leachable residue, ash or char – a significant problem faced by pyrolysis and lower temperature combustion-based systems. DMG® is NOT a “combustion” reaction – rather it is a proven thermal conversion process with significantly different physical chemistry resulting in the production of EcoSynthesis Gas, a product rich in hydrogen and other commercially desirable chemical precursors.

Other processes on the market today produce significant levels of highly toxic and potentially carcinogenic cyclic molecules. Those toxins are imbued in the residues and ashes of lower temperature systems and require that the ash and residue be land-filled for hygiene and safety.

Our system’s complete molecular conversion capabilities allow us to manage expensive toxic waste-streams and to capture the majority of both the physical and chemical energy value of the initial feed. Any resultant residue is minimal and easily managed through well-established means.

The Commercial Engineering that has led to the DMG® System has been designed to operate under extremely rigorous conditions. Utilizing a number of advances in material science, the DMG® System has evolved from its roots of a 100% ceramic thermal chamber into its Commercial design today – which utilizes a number of exotic materials, rated to temperatures of well above 1000°C, in the newly designed thermal conversion chamber. By recycling the heat generated within the system, the process is able to dramatically reduce the parasitic drag effect of operation, leading to an extremely efficient process that can operate continuously in the most strenuous of environments.

Controlling the entire DMG® process is a key to the successful production of EcoSynthesis Gas, a product rich in hydrogen and other commercially desirable chemical precursors – and is a significant component of the PowerHouse IP. Through the management of multiple temperature envelopes to the timely injection of oxidant, the control system is “self-managing” with multiple sensors and feedback systems to ensure the utmost in efficient, and most importantly, safe, operation.

The DMG® System continues to be enhanced as new breakthroughs in electronic technology material science occur. An on-going regimen of continued testing and trialing is envisioned for our operations at the Thornton Science Park with the G3 Process Demonstrator as well as new, bench-scale, operating units. The efficiency of the process has been improved over two-fold in the past 18 months alone.

The lead time in any project depends on the complexity of the application required by the customer, the feedstock, and the existing infrastructure. There is a bespoke engineering, construction, and commissioning component of the delivery of any DMG® System ordered. Our current estimate is approximately 9-12 months from payment of deposit to completion of commissioning and handing the operating plant over to the Owner/Operator.

Each system will be comprised of a number of modules, depending upon the application. One can work with the rule of thumb that a 25 tonne per day DMG® System will cost approximately £8M for a greenfield site. A DMG® System co-located at an existing site could be 30%-40% less depending upon the site engineering requirements.

Payment terms will be negotiated on a case-by-case basis, however, one may expect a 30% deposit payment to be required with milestone-based payments to be made as the DMG® system is engineered, constructed, installed and commissioned.
