We all make trash -- landfills will always be needed to accept trash that cannot be recycled or converted. Modern methods for solid waste disposal on land are difficult to explain and often misunderstood. Many people believe a landfill is a hole in the ground where our trash is dumped and left.
EnviroScape Landfill demonstrates how modern landfill systems of today differ from "dumps" of the past. The model and activities show
- leachate accumulation;
- collection and management in a landfill cell . . .
- including recirculation and off-site treatment;
- liner failure; and
- use of back-up detection and collection systems;
- closure of a completed landfill cell with a capping system; and
- comparison of a modern landfill system to old-style disposal.
EnviroScape Landfill comes with the groundwater liner
to show protection of the aquifer by modern systems as compared to contamination from the "dump."
EnviroScape Landfill is a wonderful tool for helping
people of all ages understand how a modern landfill works.
- Rain is simulated on an active landfill cell on the model, so the viewer can follow the flow of the rain through the solid waste.
- The leachate is collected and then recirculated from the tanks back through the trash or transported from the tanks to a wastewater treatment
plant (the treatment plant is not actually shown on the model.)
- Solid waste is represented with sponges and the leachate collection pumps and wells are represented with clear tubing and spray pumps.
- A landfill cover is also provided to show how rain flows off the impermeable cover or "cap" to stormwater retention areas.
What Users Say . . .
"People depend on landfills for solid waste disposal and at the same time object to landfills in their backyard because of a fear factor. The EnviroScape Landfill model helps reduce the fear factor by demonstrating the basic concepts of modern landfills. This demonstration conveys scientific concepts and practices used for environmental protection and helps make environmental studies more interesting and exciting."
N.C. VASUKI, P.E., DEE, Chief Executive Officer,
Delaware Solid Waste Authority
"The EnviroScape Landfill model is an excellent tool for demonstrating to children and adults how a modern landfill
functions as well as the importance of appropriate solid waste management methods."
