Chalmers team identifies two main challenges for bio-hydrocarbon fuel production from cheap sources

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have identified two main challenges for renewable biofuel production from cheap sources: lowering the cost of developing microbial cell factories; and establishing more efficient methods for hydrolysis of biomass to sugars for fermentation.

Rhodium Group estimates US GHG fell 2.1% in 2019, driven by coal decline

Green Car Congress

Emissions from buildings, industry and other parts of the economy rose, though less than in 2018. Natural gas generation made up much of the gap last year, as it has consistently in recent years, due to extremely cheap gas prices. Direct emissions from buildings increased by 2.2% year-on-year.

Optimizing Fume Control for Robotic Welding

Green Car Congress

Manufacturers engaged in robotic welding of automotive parts must have an effective air quality system in place to meet OSHA (Occupational Safety and Health Administration) regulations. If these systems are not well designed, manufacturers may be wasting energy and putting their plant out of environmental compliance. Source: Robovent.
