E-Waste is a Cybersecurity Problem, Too

Cars That Think

million metric tons of electronic waste in 2019, up more than 21% over five years, according to the United Nations’ most recent assessment. Only about 17% of that e-waste was recycled, and what happens to the rest can be detrimental for both human health and privacy. The conversation has been edited for length and clarity.

China researchers hydrotreat waste engine oil and scrap tire oil blend to produce diesel- and jet-range fuel

Green Car Congress

Researchers at Henan Polytechnic University in China have hydrotreated the oil derived from hydrothermal liquefaction of scrap tires (STO) with waste engine oil (WEO) using five different activated carbon-supported noble metal catalysts—Pd/C, Pt/C, Ru/C, Ir/C, and Rh/C—for the production of liquid fuels. —Liu et al.

Study shows uncovers how beetle gut microbes serve as reactor for fuel production

Green Car Congress

A paper on the study is published in the journal Nature Microbiology. This wood passes through the beetle’s complex digestive tract and is finally excreted as its waste product, politely termed frass. We study them because they are a natural model biorefinery.

Study: alcohol, biomethane and ammonia are the best-positioned fuels to reach zero net emissions for shipping; OPEX, not CAPEX challenge

Green Car Congress

A study by A.P. The joint study evaluates the interplay between economic performance of zero-emission vessels (ZEVs), technology readiness of fuels, associated machinery configurations, as well as safety and environmental considerations, all in the context of the wider energy system and the dependable production of future fuels.
