Environmental Impacts
• Provides clean runoff with very low turbidity
• No soil, chemicals or fertilizers to contaminate the water
• Obtain control over gas collection sooner than later (“close as you go”)
• Reduces overall surface emissions
• Lowers the production of leachate with incremental closures
• Durable system construction designed to safely convey internal gas
pressures, reduce unwanted releases and avoid slope stability issues
• Requires no irrigation, fertilizing, seeding or mowing
• Reduces environmental carbon footprint by up to 80%
