Real-world monitoring of air quality using low cost air quality sensors
The emergence of sensors capable of measuring the gases and particles that make up air pollution, especially in cities and industrial areas, has driven many academic studies which evaluate the sensors and compare performance against reference methodology. Such projects provide valuable and thorough assessment, but they currently work slower than the pace of low cost sensor system development. In addition, EU and US authorities are developing methodology appropriate for certification of such systems. In the...

ABC Digestate Standard Testing And Certification Program
The American Biogas Council launches its digestate standard initiative this fall. Benefits and “how-tos” of program participation are focus of ABC’s Workshop at BioCycle REFOR16. What is digestate, how do you describe it to regulators or market it to customers? That’s the critical digestate knowledge gap addressed by the American Biogas Council‘s (ABC) Digestate Standard Testing and Certification Program (Program). The final version will be unveiled at the ABC workshop on Monday,...
