Now, the city has a plan to make the McCommas landfill the first in Texas to use biotechnology to rapidly produce methane gas
If the plan works, it will essentially turn the landfill into a giant compost pile that could produce enough natural gas to serve the needs of some 16,000 homes.
“Even though it looks like we’re just burying trash, it’s really a huge science project,” said Ron Smith, assistant director of the city’s sanitation department. “It’s probably going to end up being the largest in the country.”
The Hierarchy of Waste Management
1. Reduce (Minimization) 2. Reuse 3. Recycle 4. Recovery of energy from waste by composting, anaerobic digestion, incineration etc. 5. Landfilling
