  • Methods of Analysis

    Soil grinding time is from 1-4 minutes per sample. Fine soils vs. large hard soils that need to be pounded smaller first. Clean soils without debris vs. with debris that needs to be sieved out. Material size runs from 100 grams to 2 kg. Any material smaller than 100 grams is ground by mortar and pestle. All other samples that are not dried and

  • Carbon dioxide removalWikipedia

    Carbon dioxide removal (CDR) also known as greenhouse gas removal is a process in which carbon dioxide gas (CO 2) is removed from the atmosphere and sequestered for long periods of time. These methods are also known as negative emissions technologies as they offset greenhouse gas emissions from practices such as the burning of fossil fuels.

  • Methane (CH ) Safety

    Methane is an odourless gas and is lighter than air. Because methane is lighter than air it tends to rise and accumulate near the higher stagnant parts of enclosed buildings and tightly closed manure storage pits. It is most likely to accumulate during hot humid weather. Methane is extremely difficult to detect without gas detection instruments.
