Steps to recycling cooking and vegetable oil

How can cooking or vegetable oil be recycled and reused?

The cooking or vegetable oil recycling process is dictated by the type of oil (i.e. cooking or vegetable oil) that is being recycled.

In a recycling processor, a process referred to as anaerobic digestion takes place, which breaks down the oils into a gas that can be later used as an alternative energy. Some cooking or vegetable oils can be recycled into:

  • Biofuel and biodiesel products
  • Cosmetic products 
  • Livestock feed

Can I pour cooking or vegetable oil down the drain?

As you may have picked up from the points discussed above, you should not pour your cooking or vegetable oil down the drain. Pouring oils down the drain may lead to blockages both domestically and also across main city sewage systems.

Is it okay to dump cooking oil outside?

Disposing of cooking or vegetable oil outdoors is not sustainable in terms of waste disposal. Pouring oils down the drain may lead to blockages both domestically and also across main city sewage systems.

Oils dumped outdoors may lead to animal harm and death, according to the EPA. “Vegetable oils, and animal fats share common physical properties and produce similar environmental effects”. 

The report goes on to reveal that “wildlife that becomes coated with animal fats or vegetable oils could die of hypothermia, dehydration and diarrhea, or starvation.”

Are cooking or vegetable oils bad for the soil?

In large amounts, cooking and vegetable oils may lead to problems in both soil and compost. Oils may kill plants or even prevent more plants from growing in the future, depending on the type/quality of soil.

Is composting an option?

You should only consider composting cooking oils (in very small amounts) that are vegetable oil-based, i.e. olive oil, sunflower oil, corn oil etc. This is due to the way in which aerobic processes occur in composting, and how conventional cooking oils affect this. 

In general, however, a compost pile is not the best choice for an oil disposal.
