Use of Alternate Feedstocks
Although the focus is on waste plastic and RDF feedstock, a number of other materials can be used in our pyrolysis and/or gasification systems (including scrap rubber tyres and various forms of biomass - such as woodchips and palm kernels).
SCRAP RUBBER TYRES
- As ECI look to channel more of the plastic derived oil to a further refinement stage of processing, bulk supply chain relationships as developed with the earlier stage industrial / manufacturing sector clientele, could be maintained by the introduction of a substitute line in the form of bunker fuel / heating oil produced from waste rubber tyres.
Oil from waste rubber tyres is not deemed suitable for further refining to diesel and other value-add fuels due to the prevalence of contaminates, colour and odour related issues. However, as a heating fuel source, it actually commands a slightly better price than that from plastic – due to its higher viscosity & thicker state (i.e. burns better / more efficient).
Although oil yields from scrap tyre feedstock are markedly less than that from plastic (45 % v 75+ %), values which attach to recovery & sale of other materials from the production process (carbon black; metal) still render the exercise economically viable.
Accepting the pyrolysis process is basically similar, and ECI has access to vast quantities of discarded tyres, it is nevertheless the case that this additional revenue generating potential does not presently warrant our direct attention given the focus on waste plastic derived fuel production within the context of pyrolysis conversion.
In terms of gas production from scrap rubber tyre feedstock, however, ECI plan to make use of this heating source (in substitution of propane gas) to support the operation of a multi-system pyrolysis facility planned for Saraburu (Thailand) – via a direct feed from a JV Partner gasification plant operation.
- In line with an expanded processing capability aligned to the development of our 3rd generation of conversion technology, ECI expect to be in a position where the range of material input could also include the following:
Municipal Solid Waste (MSW)
- Auto Shredder Residue (ASR): plastics, rubber & fabrics, etc. from vehicles
- Organic Waste: wood chips, crude oil sludge, paper pulp sludge, etc.
- Medical Waste from hospitals, clinics & related environments
- Electronic Waste: computer boards, mobile phone cases, etc.
- Different types of plastics, including: Mixed Plastic (HDPE, LDPE, PE, PP, Nylon, Teflon, PS, ABS, FRP) and Multi Layered Plastic
