Waste Education

At DSI and LSI, we prioritize sustainable waste disposal, utilizing both incineration and modern landfill practices. Approximately 35% of our waste undergoes incineration, while our landfills adhere to stringent Subtitle D standards, featuring lined structures for environmental and community protection. Regular inspections ensure compliance, including leachate water collection to safeguard groundwater and wetlands. The collected water is treated at a facility for environmental preservation.

Despite higher energy recovery on the waste hierarchy chart, our modern landfill stands out, generating enough electricity to power 3600 homes daily. Operated privately, it requires no public taxpayer money, contributing significantly—upwards of half a million dollars—to the municipality for host fees, supporting general fund initiatives.

Former landfills, once capped with synthetic membranes, clay, and topsoil, are transformed into valuable community assets such as, parks, wildlife habitats, and recreational facilities. Continuous monitoring ensures environmental protection and the sustained integrity of these capped landfills. Landfill gas emerges as a reliable and eco-friendly energy source, endorsed by the EPA. Beyond embracing renewable energy, it reduces reliance on foreign energy, it offers constant output, predictability, and stability in fuel prices. With over 95% energy availability, landfill gas-to-energy projects contribute significantly to environmental sustainability, offsetting non-renewable resources. These initiatives play a crucial role in North America's pursuit of alternative energy sources and environmental well-being.

Liners form the primary barrier between the landfill’s content and the surrounding environment. State-of-the-art composite liners made from both synthetic and natural materials. The exact composition of these liners depends on the nature of the waste that will occupy the landfill itself. Most liners include a high density polyethylene (HDPE) geomembrane over a layer of recompacted clay at least two feet thick. The HDPE membrane is laid in sheets and heat welded by hand. Each seam is inspected and tested to prevent leaks. Quality control managers oversee every step of liner construction.
