Some greenhouse gas emissions are present, but they are lower with bokashi composting than with the traditional composting technique.
Yes, but greenhouse gas emissions are significantly lower in comparison with traditional composting. Research shows that bokashi composting retains almost 60% more nutrients, which would otherwise be released in the form of greenhouse gases during traditional composting [Hitman et al.,2013]. Research that compared traditional (aerobic) composting to bokashi composting showed that the amount of CO2e produced per ton of starting material is ten times lower in bokashi composting [Hitman et al., 2013]. Some major gases that appear in smaller quantities are CO2, CH4 and NO2.
