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.

Panasonic develops highly efficient artificial photosynthesis system with gallium nitride semiconductor for conversion of CO2 to formic acid

Green Car Congress

This will make it possible to realize a simple and compact system for capturing and converting wasted carbon dioxide from incinerators and electric generation plants, according to Panasonic. The conversion efficiency of solar energy to chemical energy was 0.03-0.04%. Applied Physics Letters , Volume 100, Issue 24, id.

PNNL biocrude-to-diesel demo passes 2,000-hour catalyst stability milestone

Green Car Congress

The biocrude oil came from many different sources, including wastewater sludge from Detroit, and food waste collected from prison and an army base. The research showed that essentially any biocrude, regardless of wet-waste sources, could be used in the process and the catalyst remained robust during the entire run.

LanzaTech collaborating with Swayana to convert waste gases from ferroalloy production to ethanol

Green Car Congress

South African engineering company Swayana has signed a Memorandum of Understanding (MoU) with LanzaTech to collaborate on developing projects for the production of ethanol and higher value products from waste gases in the ferroalloy and titania smelting sectors. In all cases, however, the production of ferroalloys is energy-intensive.

MISC, Samsung Heavy, Lloyd’s Register and MAN partner to develop ammonia-fueled tanker

Green Car Congress

The energy conversion rate of this system is higher than that of biomaterial-based systems, but the production pathway cannot tap into potential energy sources such as waste biomass. This builds on the technology development pathway that MAN ES presented at the NH3 Energy+ Topical Conference at Pittsburgh in October 2018.
