IIncineration, recycling, putting into landfill ? Print E-mail

Pollution of nature

Between 60 to 85% of the waste collected on the littoral are plastics.

Incineration

It consists in burning waste in ovens at a temperature of 700°C to 900°C. This process transforms waste into volatile compounds and ashes. The pollution emissions are limited and controlled. The incineration of certain plastics is an important source of creation of dioxins (very stable dangerous compounds chemical, not easily degradable by the organization). However it offers an alternative to the putting into landfill because all cannot be recycled. The processes of separation, purification and working are still unsuited or too expensive.

Recycling

Recycling is in the course of research, some solutions were brought but there is the difficult problem of recovery, separation, handling, storage...

The rates of recovery and recycling of the plastics are very weak, just few % which constitutes a singularity compared to other materials of consumption: metal, glass, paper.

The plastic remains difficult to recycle. It is not a single material. Thousands of chemical formulas used for the various products obstruct considerably the recovery and the putting into landfill.The plastics which can be recycled are PP, PET and HDPE.

The manufacturers should Re-conceive their products, including packaging in order to make them recyclable.

Caution: the plastic products become sooner or later waste. Recycling does only delayed the inevitable incineration or putting into landfill. It leaves the open door to the increase of the production instead of truly replacing the first production.

The putting into landfill

Pesticides, dyes, heavy metals, stabilizers, additives are released in nature during its degradation into landfill. The accumulation of plastic waste into landfill became a global issue, particularly packaging and the plastic bags.
