A study demonstrated that solid recovered fuel created from nonrecycled plastics and other waste can power energy-intensive commercial and industrial operations. (Source: Balcones Resources/University of Texas at Austin)
Definitely an interesting idea to create fuel from non-recycled plastics. But while there are obvious energy benefits, what about the emissions and environmental/human safety factor? I, for one, am not a fan of breathing in what would seem to be plastic residue.
Beth, SRF is created by compression, not by burning. The emissions discussed here are from the normal operation of the cement kiln, not from creating the fuel. Cement kiln emissions were lower using this fuel than using coal.
The idea is to use a resource that's being wasted and would otherwise end up producing C02, plus get a cleaner-burning fuel. SRF is more common in Europe and other countries, but less so in the US, as we discuss here http://www.designnews.com/author.asp?section_id=1392&doc_id=242808
Thanks, Nadine. This is a different type of fuel than JBI makes. It's a solid recovered fuel (SRF) that mixes plastic and other waste, mostly paper-based, via compression into pellets that can be burned. As we reported here http://www.designnews.com/author.asp?section_id=1392&doc_id=242808 JBI does something quite different: plastics to fuel (PTF) using pyrolysis (thermochemical, not burning), which creates fuel oil out of plastics via chemical, not mechanical, processes. Regarding commercialization, I don't think anything in particular is keeping these technologies from the market. They've all been in R&D for awhile and are in process of being scaled up. North America is considerably behind Europe in this field, partly because (I've been told) we've had more room for landfills so less motivation.
Thanks for the clarification on the different processes Ann. I was referring to the fact that both use post-consumer trash or recyclables to make fuel. I should have been clearer.
How is Europe ahead of North America using this? I haven't heard of any large-scale use of this type of fuel.
Most new or expanded landfills in the US are placed in extremely poor communities. I don't think we have the space. I think it's that marginalized areas are easily manipulated here. It's hard to focus on protecting the environment when the kids are hungry.
Nadine, to clarify, these do not use recyclables, but items that can't be recycled. To answer your question, during the reporting for this feature article on fuels from plastic: http://www.designnews.com/author.asp?section_id=1392&doc_id=242808 I learned from industry experts that solid recovery fuel (SRF) and/or refuse derived fuel (RDF) processes, which mix paper with plastic, are more common in Europe, but not yet so in North America. I also learned that, in general, because there's much less landfill space--due to much smaller geography and higher population density per square mile--Europe is farther along in R&D and also deployment of turning plastics into fuel, meaning prevalence, not scale of deployment.
The carbon emissons are only 1.5 % ? that is pitiful. This is probably within experimental error. why bother with this approach? Is SO2 that big an issue to scrub? I suggest it is misleading to take huge landfill numbers and mulitply by some small possible not even real % and claim that recovering energy from SRF s is equal to 700,000 homes /yr.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
