Work has begun to expand methane collection, containment and monitoring after the potentially explosive gas was found seeping from a closed landfill in western Michigan.

The Grand Rapids Press reports that work started last month to collect the gas leaking from decomposing waste underneath the soil at Kentwood Landfill near Grand Rapids.

Crews worked to drill a 94-foot-deep (28.6-meter-deep) hole into the soil, sediment and mostly decomposed garbage Sept. 5. The holes are designed to draw methane from deep and shallow underground areas of the old landfill.

Grand Rapids building $30 million bio-digester

As locally owned Founders Brewing Company continues to grow so has its stream of highly concentrated food waste.  In response Grand Rapids' wastewater division is preparing to build a new bio-digester at its water resource recovery facility to handle that waste. The bio-digester, including a new pipe and sludge treatment system, is expected to cost the city nearly $30 million.

The city's environmental services manager, Mike Lunn says, while that is a lot of money to spend, the bio-digester financially was the lesser of two evils.

Kent County

Kent County officials now have a plan for dealing with methane gas migration at a west Michigan landfill.

Back in August, Kent County officials were busy investigating ways to resolve the migration of methane gas from a closed Kentwood landfill.

Gas detection equipment was installed and air quality tested. There were meetings open to the public.
