What Are the Negative Effects of Used Cooking Oil on the Environment?

Nowadays, environmental pollution is a very important problem. Very often we seem to forget that our daily actions have an impact on the environment. Used cooking oil poured into the drain can have the following harmful effects that should be considered:

  • As we all know, oil does not mix with water, but it remains on the surface and forms something like a barrier layer that prevents the water from oxidizing properly. This leads to the death of the animals that live in it. Some of the oil sticks to the gills and scales of the fish and animals can suffocate and die.
  • Used cooking oil clogs pipes if you pour it in the sink. When mixed with chemicals from cleaning products, it forms a hard layer that traps residue and bacteria. This leads to bad odors in the drains and increases the risk of pests such as cockroaches and rodents in the kitchen. You should also keep in mind that repairing a clogged drain is expensive.
  • If you dump used cooking oil in the garden for a long period of time, this dirt will make the soil infertile.
