Read about our approach to external linking. “Under the EPA’s bioreactor research and development rule, you can apply for a permit to build an R&D [research and development] landfill,” Sullivan says. However, the airflow rates required do vary greatly and need to be set by experts, in the knowledge of the rates of possible ingress at the site, under the maximum gas generation periods (normally during the highest rates of falling atmospheric pressure). Here in Texas, we figure 20 - 25 years. Inert Waste Disposal – Is My Waste Inert? The exceptions to this requirement are small landfills that receive less than 20 tons of solid waste per day, and facilities that can demonstrate that there is no potential for the migration of hazardous constituents from the unit into the groundwater.

This technique has been used in the construction of many warehouses, supermarkets, and sports facilities. It is also essential that if services such as electricity, gas, water, drainage, telecoms related etc, penetrate the slab (or raft) that they are also sealed in a satisfactory, and truly permanent, fashion.
