Degradation and Landfill Mechanics
Inside the Landfill
EPI’s film is made degradable with the TDPA® technology. The film will start to degrade through the exposure to heat, mechanical stress and/or sunlight. Upon burial in a landfill, the film will continue to degrade because of the heat and the mechanical stress inside a landfill.
As degradation proceeds, EPI's degradable films will lose their mechanical properties. They will eventually become brittle and fragmented and allow the biogas and leachate to flow to the gas and leachate collection systems.
The degradation of EPI’s films will produce non-toxic by-products.

Biogas/Leachate Movement
The use of improper waste covering materials such as low permeability soil and non-degradable film could lead to the formation of impermeable barriers within the landfill. These barriers would result in undesirable lateral migration of biogas/leachate, thus affecting the effectiveness of biogas/leachate collection.
Because EPI's films are degradable, they will allow the biogas/leachate to flow through for collection.
