The Challenge:

The plastic industry is one of the world's largest consumers of oil; over five million barrels a day are used in the creation of hundreds of different polymers for consumers and industry. Cheap, lightweight, and extremely versatile, plastics have found their way into almost every product imaginable. These products, often designed for single use, will usually be disposed of in landfills along with other domestic and commercial wastes. Despite increased recycling efforts, we still incinerate more plastic than we recycle and even then 80% of the world's plastic still ends up going to landfills. 

The Greater Vancouver Regional District of British Columbia, like many other locations in North America, is trying to find sustainable long-term solutions to its waste management problems. Although some of the easier-to-recycle and in-demand polymers such as polyethylene and PET are baled and usually sent to the Far East for cheap processing, many other plastics such as silage wrap, multi-layer films or laminates, contaminated plastics, industrial waste, and the residual plastic waste from previous recycling operations are destined for landfill. There is currently no alternative sustainable use for these mixed waste plastics and considering the amount of oil contained within them, there exists a significant opportunity on a global scale to recover this value.

The Solution:

Klean Industries designs and develops facilities that convert waste plastics into high-quality oils. The systems use a continuous liquefaction technology that indirectly heats the plastic waste and a unique catalytic reaction to generate hydrocarbon gases which are then cooled and condensed to produce ASTM spec diesel as well as a proprietary blend of heating fuel. These oils not only exceed regulatory standards but can be used in any diesel engines, trucks, buses, trains, boats, heavy equipment, and generators with no engine modification. A Klean plant can produce approximately 950 liters of high-grade diesel fuel from each tonne of waste plastic. Different polymers can be processed together without any sorting and typical contaminants such as grit, paper, metal, food residue, and oils do not need to be removed before treatment. The advanced system has the capability to take high loads of PVC and PET along with the ideal polyolefin plastics without damaging the reactor or producing unacceptably high emissions. 

The technology originates from Japan, has been in commercial operation for over twenty years and there are now dozens of reference facilities that have the capacity of producing fuels at a rate of over five hundred liters per hour. Klean's distillate fuel is not only greener than virgin fuels, due to its reduced carbon footprint, but it is also a superior product due to its cleaner-burning properties and high cetane rating.

Klean is planning to establish the first plastic-to-diesel facility in British Columbia, which the company claims will not only be low impact visually but also environmentally, as emissions levels are just a fraction of those permitted. The company already has agreements to sell fuel products locally and has well-established relationships within the British Columbia fuel retailing and plastic recycling industry that provide feedstock and off-take opportunities.

Klean's new reactors are more proven, energy-efficient, and inherently safer than traditional process equipment, but have low operational costs and minimal maintenance. Klean plans to establish up to fifteen similar facilities across North America and Europe and is actively discussing opportunities with a number of organizations that currently dispose of large volumes of plastic suitable to the KleanFuel process on a build, own, and operate, joint venture, and partnership basis. 

The Outcome:

  • 5000 TPA of mixed plastics waste diverted from landfill
  • 5,000,000 liters a year of green diesel-grade fuels and heating oil generated from waste
  • 15,000 tonnes of carbon dioxide offset
  • Preservation of fossil fuels
  • New jobs and taxes generated from the green economy
This project addresses the SDGs by taking into account the following goals and associated targets. It contributes to ensuring sustainable consumption and production patterns by coming up with a sustainable waste treatment framework (Goal 12). Through a safe and inclusive waste disposal system, the SDG strives to protect ecosystems and prevent biodiversity loss (Goal 15).
