CDP Waste2Energy uses depolymerisation, a process for converting long-chained polymers into shorter-chained molecules to reduce complex organic materials into a renewable, synthetic diesel. The patent-pending process uses a purpose-designed plant that breaks large molecules, such as those found in plastics and wood, into smaller molecules found in liquid fuels. The liquid fuel that is produced is suitable for diesel applications, including power generation, shipping, farming and mining.
The CDP Waste2Energy process deals with waste that is a mixture of biomass and fossil fuel-derived materials from a variety of sources:
- Biomass, including waste plant material, timber, bio-derived residues like leaves and straw;
- Many kinds of plastics and synthetic petrochemical products (PP, PET, SBR, etc.);
- Fibrous materials, including paper & cardboard;
- Combined products incorporating plastics & paper components, such as coffee cups, labels and packaging, which is often difficult for conventional recyclers to utilise;
- Animal waste;
- Coal, crude oil, bitumen, old tyres and refinery residues; and
- Waste oil, fat and bio-solids, such as food wastes.
The CDP Waste2Energy process produces a renewable diesel fuel that:
- has a lower carbon emission footprint than conventional petroleum fuels;
- is produced at a reduced cost per litre relative to the refining of diesel from crude oil;
- is not strongly acidic (unlike oils produced using pyrolysis as an EfW process);
- meets the bio-fuel mandates in Queensland, Australia and New South Wales, Australia, for bio-derived fuel sources; and
- results in a reduction of engine wear and tear because of reduced fuel corrosivity.
- Low temperature and catalysts used – no noxious gases are produced by the process, unlike incineration or gasification which require treatments with scrubbers or other processes to reduce emissions.
- The CDP process deoxygenates the feed as it converts to fuel, requiring only minimal, conventional desulphurisation processes to then meet the ultra-low sulphur diesel specification.
- Does not consume any water, reducing the impact on the environment and community, unlike technologies such as gasification and other supercritical processes.
- A lower carbon footprint than other energy from waste processes as a consequence of the reduced energy requirement due to the relatively low reaction temperatures unlike other upgrading technologies such as pyrolysis and gasification.
CDP Waste2Energy has undertaken significant testing to ensure credibility of its process, including:
- Independent emissions testing reports for solids, liquids and waste streams generated.
- Extensive research in collaboration with the University of Queensland.
- Partnerships with credible and reputable international multi-discipline corporations to ensure effective project development that takes into account local community and environmental sensitivities.
- Transparency through the publication of research and testing results carried out under the academic scrutiny of the University of Queensland.
