Ecological properties
Mechanical recycling
make new products from plastic granules
estages
Floating
Agglutination
Separation and crushing
Extrusion
Pelletising
Energetic recycling
produce electricity from incinerating plastics
Chemical recycling
make new materials from the original component of plastic residues
Classification
Thernostable plastics
Elastomers
Thermoplastics
origin
Natural plastics
are directly obtained from raw vegetable materials
Examples
Cellulose or latex
Synthetic plastics
are made from compounds extracted from petroleum, natural gas and carbon
Transformation of plastics
also called polymerisation
we can add
Fibreglass, textile fibres, paper, silica and
sawdust
to
reduce the production cost
Chemical additivies
to increase
flexibility
and to strengthen the polymers
Pigments
to give
colour
to the plastics
