Grease traps

Grease traps stop solid grease and light waste particles from entering our waterways and landfill. They need regular maintenance to ensure optimal functionality and prevent events like blockages, overspills and flooding.

Depending on the size of your business, grease traps should be serviced between two and six times annually.

REMONDIS conducts safe and responsible grease trap cleaning services, where waste collected is recycled into mulch and compost and then reused as new products.
