Non-recycled plastics (NRPs), which make up 12.4 percent of municipal solid waste (MSW), have high value as a feedstock for conversion to energy or fuel because of their potentially significant heating value. (Source: Gershman, Brickner & Bratton/US EPA)
Ann, this was really interesting. The other product of the process, shown in the last slide, is ash. Did your sources say anything about it, such as what volume / weight percentage is it compared to the original feedstock, or if the ash has a use, its toxicity?
I agree, Rob, and Ann has been on top of this. I really like to see the efforts around re-use of material, especially plastic, that would otherwise just become landfill or ocean pollution. If this material was created and used then it makes sense that it can be deconstructed and reused. Thanks for keeping a close eye on these efforts.
Thanks Elizabeth and Rob. This is an area that interests me a lot, because it hits so many different targets: getting non-recycled plastic out of the environment, using waste creatively, re-using some already produced and very expensively-produced energy sources, and making non-petroleum-derived fuel.
TJ searching the PDF of the report on "ash" produced these statements: "The combustion process and cleaning of the gases produce fly and bottom ash, further processed to remove metals for recycling. The ash can be used as alternative daily cover at landfills or as construction aggregate." There's also some further discussion of how ash is created and handled within different up-/down-cross-draft gasification systems.
Elizabeth, I am concerned about the tons of plastic and other wastes being discharged at sea instead of used for energy. I wonder if a gasification plant could be constructed aboard cruise ships, providing fuel energy as well as reducing the overboard waste.
This seems like a very good solution to the problem of plastic but any idea about what is approximate cost of setting up a gasification system and the running cost? It can be a key factor in determining the feasibility of this process?
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
SABIC's lightweighting polycarbonate glazing materials have appeared for the first time in a production car: the rear quarter window of Toyota's special edition 86 GRMN sports car, where they're saving 50% of its weight compared to conventional glass.
Design engineers play a big role in selecting both suppliers and materials for their designs. Our most recent Design News Materials Survey says they continue to be highly involved, in some ways even more than the last time we asked to peek inside their cubicles.
Daihatsu is one of the first carmakers to customize car exteriors using 3D printing's mass customization capabilities. Effect Skins -- small exterior bumper and fender panels in different colors and textures -- can be ordered for its Copen convertible.
Several new products in this group of new adhesives, coatings, and sealants are formulated to protect sensitive electronic components, or to seal components of commercial and military aircraft. Others are designed to operate in tough, messy, dirty oil & gas operations, or for rotary applications and motors.
