Good fences make good neighbors... and they prevent headaches. Mallinckrodt, Inc., a Covidien company, the world's largest producer of acetaminophen, the active ingredient in many headache remedies, recognized the opportunity to team with its neighbor to the west, the North Wake Solid Waste Landfill.
Mallinckrodt worked with Wake County (landfill owner) and DTE Biomass Energy (project developer) to develop a project to pipe landfill gas (LFG) "under the fence" to a 33 million Btu/hr steam boiler, specifically designed to burn LFG. The boiler consistently and reliably met nearly half of the plant's 50,000 pound-per-hour steam demand.
The project's highlights include:
- Generates clean, renewable energy.
- Prevents greenhouse gas emissions.
- Generates awareness and demand for renewable energy.
In 2006, Mallinckrodt converted one of its existing natural gas-fired boilers to combust a mixture of LFG and natural gas, increasing LFG usage. The DTE boiler became a back-up unit at that point. In 2009, Mallinckrodt increased its LFG usage again, to ship some steam to a sister company next door.
