Waste to Energy Applications

Public Sector Landfill

There is growing international focus on reducing landfill with many countries around the world implementing Zero Waste to Landfill strategies. Governments and businesses have made the reduction of waste to landfill a priority.

The GrahamTek Waste to Energy technology offers a solution to support these Zero Waste to Landfill strategies, and prevents most hydrocarbon plastic and rubber based waste streams from going to landfill. Our technology reduces volumetric landfill mass by up to 97%, which reduces the cost of sending waste to landfills, the costs of managing landfills as well as limiting the need for new landfills.

The EU Commission on Waste Management has presented legislative proposals for higher recycling rates. The goal is to recycle at least 70% of municipal waste by 2030, while the packaging industry is required to achieve 80% reduction. Currently on average 40% of waste is recycled in the European Union.

Private Sector Landfill

Private Sector landfill owners make money from operating landfills and storing waste in a landfill airspace. With growing urbanisation landfill space either needs to be increased or existing landfill space needs to be optimised. 

The GrahamTek Waste-to-Energy system allows for landfill owners to increase their revenues by “doubling-up” on gate fees charged for landfill waste while using the GrahamTek Waste-to-Energy system to produce Fuel Oils or Electricity from the waste streams already received at the site. This has a compounding effect for landfill owners as it reduces the Operating Expense for landfill and extends the airspace life of the landfill as only 5% or less of the waste stream is eventually landfilled.

Medical Waste

The GrahamTek technology is uniquely qualified to dispose of medical hydrocarbon waste (excluding anatomical waste). The typical medical waste stream consisting of sharps and surgical material can be processed directly in the system as the elevated temperature of the system is sufficient to kill pathogens. In development testing this waste stream resulted in some of the highest yield for fuel oils, with additional byproducts such as steel and glass.

Waste Tyres

Waste Tyres are bulky, and 75% of the space a tyre occupies is void, so that the landfilling of scrap tyres has several difficulties:

  • Whole tyre landfilling requires a large amount of space
  • Tyres tend to float or rise in a landfill and come to the surface
  • The void space provides potential sites for the harbouring of rodents

Shredding the tyre eliminates the above problems but requires high processing costs.

Because of the above difficulties and the resulting high costs, tyre stockpiles remain a difficult waste stream globally. Waste tyre stockpiles have large potential associated risks these are; Health Risk (due to Rodents, mosquitos), Fire Hazards (difficult to ignite but equally difficult to extinguish once burning). The GrahamTek Waste-to-Energy system can be installed near existing tyre stockpiles and provide a means to process the existing stock pile and new waste tyres delivered to the stockpile.

Marine Eco Clean-ups

The ocean remains one of the most expansive, mysterious and diverse places on Earth. Unfortunately, it is being threatened by pollution; marine life is dying, and as a result the balance of the whole oceanic ecosystem is threatened. If we are to preserve our oceans, drastic measures have to be taken in order to combat this pollution.

Plastic is the most common element found in the ocean. It is harmful for the environment as it does not get broken down easily and is often mistaken for food by marine animals.

There is an island of garbage twice the size of Texas inside the Pacific Ocean: the North Pacific Gyre off the coast of California is the largest oceanic garbage site in the entire world. There, the number of floating plastic pieces outnumbers total marine life in the immediate vicinity by six to one.

The GrahamTek system can be ship based and therefore used on the ocean as a mega waste recovery unit to remove these plastics from the ocean while generating Fuel Oils.


Scrap Plastic and E-Waste

Bulk plastics from vehicle scrap recycling, household and industrial appliance disposal as well as old computers and office equipment take up a large volume of landfill space. The GrahamTek technology can process these waste streams with up a 95% reduction in landfill space and with waste to fuel yields in excess of 63%.
