Common waste streams generated from these activities include spent engine fluids, batteries, worn metal parts, and waste solvents. Marina operators have a number of options available to reduce or recycle these waste streams. Proper management of spent engine fluids such as waste oil and used anti-freeze will prevent these materials from contaminating nearby surface waters. Individual waste streams should be collected in separate containers and segregated from other waste streams including trash and debris. These measures will reduce the volume of waste to be managed and improve the recycling capability of the waste streams.
Marinas working together can implement a recycling program for their area using an outside service.
Waste solvents from parts-cleaning operations can be recovered by using an onsite distillation unit. In addition, there are offsite solvent recovery services available to the marina operator. Hazardous wastes from solvent cleaning operations can be completely eliminated by switching to an alternative cleaning method such as an aqueous cleaning system. Citrus-based cleaners are also an effective substitute. Worn parts and scrap metal can be sold to a parts remanufacturer or metal recycler.
