Spill Trays and Drip Trays

Spill trays and drip trays at household waste recycling centres protect the site from leaks from stored containers and drums. They are an essential part of the infrastructure for storing liquid waste in line with environmental protection regulations.

They are essential equipment at stations accepting chemicals and used oils.

Site staff should check the spill tray regularly for spilt liquid and empty it when necessary, before it fills to its usable capacity. These checks should be recorded in the site's internal records, especially ahead of periodic external inspections.

Spill trays complete the full equipment of a household waste recycling centre.

The usable capacity of a spill tray should exceed the volume of the largest single container or drum placed at the station. This is the basic design rule for such protection and ensures that, even if the largest tank fails completely, the liquid will not overflow beyond the containment area. At stations holding several containers at once, the combined capacity of all tanks placed on the shared tray must also be taken into account.

The material is chosen according to the type of liquid stored. Polyethylene works well for oils and most operating fluids, while highly corrosive substances or solvents may require trays made of stainless steel or materials with higher chemical resistance, selected individually for the specific substance in line with its safety data sheet.

Modular trays that can be joined into a larger set make it easier to expand the station as the number of fractions accepted at the recycling centre grows, without replacing all the infrastructure at once. This solution is particularly valued by local authorities planning to extend the range of hazardous waste they accept gradually, as their capital budget allows.

Drive-on grids fitted to the tray make it easier to position drums and containers safely with a pallet truck, while protecting the tray floor from accidental puncture when equipment is being manoeuvred. A well-designed grid should be easy to remove so that the inside of the tray can be cleaned regularly.

For outdoor stations exposed to rain, a spill tray with a roof or an additional cover is worth considering to limit the build-up of rainwater in the containment area, as excess water reduces the tray's real protective capacity in the event of an actual leak from a stored container.

The number of stations with spill trays should be planned in line with the expected range of hazardous waste accepted. A recycling centre accepting oils, paints and solvents at the same time should separate these fractions onto different trays, as mixing different substances in one containment area may create an additional risk of chemical reaction.
