Leachate
Leachate is the liquid that forms when water passes through waste materials, like in landfills or composting facilities. Think of it like tea - when water filters through waste, it picks up various substances along the way. Managing leachate is a crucial part of waste management because this liquid can affect the environment if not handled properly. Companies in recycling and waste management need specialists who understand how to collect, treat, and monitor leachate to protect the environment and comply with regulations.
