Waste management, its collection, recycling and disposal is a challenge faced by everyone.  The management and safe disposal of unwanted ocean plastics, industrial wastes and household refuse is a complex and challenging problem.  Nex Energy Systems Asia (NESA) presents a solution to improve waste management and landfill reduction by effectively converting the many different forms of waste as raw material feedstock for conversion into renewable and sustainable energy, by employing an advancement in waste gasification pyrolysis called thermolyzation.

NESA represents the Kunststoff – und Umwelttechnik GmbH (KUG) technology, a patented slow pyrolysis gasification technology.  The KUG gasification system uses thermolyzation in a patented 3 stage reactor system, in an oxygen free environment.  The three stage oxygen free reactors improve the quality of the gas output (a higher BTU rating than comparable pyrolysis technology), reduces the toxins within the syngas output, reduces the tar content by the additional cracking in the later stage reactions, and enables the gas to be directly used in a gas powered electrical generator thereby minimising energy losses enroute to final power generation.

The KUG technology is a breakthrough technology that increases the efficiency of waste to energy (WTE) systems to the point of making them unequivocally economical to install and manage at nearly every landfill site, creating sustainable electricity for local the community.  The mass energy balance and carbon balances are both very positive and will contribute to local the local power grid and the national carbon accounts.

Additionally the conversion of syngas to fuels is already a proven technology, and NESA is presenting the KUG syngas as a unique chemistry for improved conversion to diesel, aviation fuel and hydrogen as compared to other pyrolysis syngas technologies. NESA will continuing to work with its development partners to test and build a “plastics to fuels” plant and demonstrate its economic viability at scale



To positively impact on the amount of waste material safely converted into usable energy creating a more sustainable low carbon future.


Communities and countries alike, will benefit from NESAs advanced conversion technology as a source of sustainable energy supply from waste streams as feedstock


NESA’s technology partners are leaders in their field.  Partnering with KUG, brings to the fore a leading gasification technology, producing higher quality syngas, with better toxin control and fewer energy losses.

What We Build

The Energy & Technology For a Low Carbon Future

Electrical Generation

40 TPD of generalized Municipal Solid Waste (MSW) = 2.15 MW / hr of Electrical Output = 51.6 MW / day Electrical Output = More than 17,000 MW of annual Electrical Output

Carbon Savings

40 TPD generalized Municipal Solid Waste (MSW) = up 100 ton / day of carbon savings when replacing electricity otherwise produced by a brown coal power station


Modular system allows scalable sizing Module sizes built on: 40 TPD, 80 TPD, 160 TPD

Waste to Fuels

Industrial plastic wastes offer the greatest opportunity for waste to fuels generation. NESA is actively working to build its first waste to fuels plant based on plastic as a waste stream

Clean Tech Investment

Patents and Investment Guarantees


The KUG system has US and German-European patents.  NESA holds the license to sell and operate the KUG technologies in Asia, Australia and New Zealand.

Investment Guarantee

All new technology developments require certain guarantees and assurances.  The NESA project offering which uses KUG technology is project guaranteed by Munich Re insurance.  Details of the depth of the Munich Re coverage can be disclosed and confirmed with investors and client partners.

A syngas generator warranty can be void if the incorrect component gas is supplied to a generator.  KUG syngas (without added refinement) has been tested and guaranteed for direct supply to the following gas generator manufacturer systems; Siemens AG, GE Jenbacher, Bayer, Duetz and MWM (a division of Caterpillar). 

A project partnership with NESA is investment guaranteed from the technology to end electrical output. 


Bi Product Strategy

Co-benefits of Waste to Energy technologies

The NESA waste to energy approach enables direct generation of electricity from syngas, as well several bi-products which have direct commercial and environmental benefit.  The type and volume of bi-products is determined by the waste input, for example a predominantly biomass input will have a higher level of char bi-product as compared to a predominantly plastic input. 

Bi-products such as char, coke, carbon black and charcoal are produced and can be commercially sold or redirected back into the gasifier to increase the electricity output per ton of input waste. 

Depending on the end user jurisdiction the use of char to improve soil carbon capture has added carbon capture benefits beyond the carbon value of the char alone and can further benefit national carbon accounting balances, when implemented at scale.

When using MSW as the feedstock, the incorporation of heavy metals and toxins is inevitable in the waste stream.  The KUG gasification process can capture and concentrate those heavy metals and toxins and lock them into a small volume waste output that can be properly managed at a registered toxic management facility, not a traditional open landfill, at risk of toxic leachate.  Mass excavation and gasification of hazardous open landfill sites, exhibiting dangerous levels of leachate can convert what is an environmental hazard into a controlled smaller toxic concentrate to be managed by a registered facility. 


Waste to energy systems are a firm part of the waste management hierarchy and require deliberate action at the national and local scale to better manage them as part of the circular economy.
