Land use: Even distribution on the soil of animal farming effluent, soil improver, fertilizer, plant health products, wastewater treatment plant sludge, etc.
Landfill: A facility designed to treat and store waste under optimum conditions of safety. In the European Union, there are three categories of landfills:
- Landfills for stabilized or inert hazardous waste (Class 1 in France);
- Landfills for municipal and similar waste (Class 2 in France);
- Landfills for HW (household waste) and non-hazardous industrial waste, that is, non-hazardous and inert waste (Class 3 in France).
Leachate: When landfilled, under the combined action of rainwater and natural fermentation, waste produces a liquid fraction called “leachate.” With a high organic mater and trace element content, this leachate cannot be discharged directly into the natural environment; it must be carefully collected and treated.
Lipofit: Grease concentrate produced by the Lipoval treatment process for greasy liquid waste. Lipofit’s characteristics are close to those of heavy fuel oil, except that it has a significantly lower sulfur content. Under regulations, it is considered as a fuel in its own right that can be used in facilities classified as 2910B (i.e., combustion units).
Lipoval: A separation process for greasy liquid waste mainly from restaurant grease traps (80%), but also from food industry and wastewater treatment plant oil removal units. The Lipoval process involves the dynamic separation of fatty waste into three phases: a fatty concentrate recoverable as a replacement fuel (Lipofit), solid sediment and a treated aqueous phase that can be released into the wastewater system.
