This is no doubt a reflection of the fact that new biogas projects are much more frequent than new landfill projects. Instead of paying to have their garbage hauled away to a landfill, many companies have preferred to invest in biogas systems that produce energy while reducing waste. Communities often push back on initiatives to start up large landfills in their regions, while they might be more favorable to biogas initiatives. Biogas projects are more tenable because they are smaller scale and do not consume large tracts of valuable land. By design, biogas digesters are covered and are therefore not as offensive to neighbors or attractive to vermin.
