G. CENAAS 2014 / 2015
Recycling is a process to change materials into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw
materials, reduce energy usage, reduce air pollution and water pollution.
PAPER RECYCLING
Paper recycling is the process of turning waste paper into new paper products. There are three categories of
paper that can be used as feedstocks for making recycled paper: mill broke, pre-consumer waste,
and post-consumer waste.

PLASTIC RECYCLING
Plastic recycling is the process of recovering scrap or waste plastic and reprocessing the material into useful
products, sometimes complete different in form from their original state.

GLASS RECYCLING
Glass recycling is the process of turning waste glass into usable products.
Glass waste should be separated by chemical composition, and then,
depending on the end use and local processing capabilities, might also have to
be separated into different colors.
OBJECTS MADE WITH GLASSRECYCLED
The consumer throws glass into a recycle bin.
Glass is taken from the bin and taken to a glass treatment plant.
The glass is sorted by colour and washed to remove any impurities.
The glass is then crushed and melted, then moulded into new products such as bottles and jars.
The glass is then sent back to the shops ready to be used again.
Glass does not degrade through the recycling process, so it can be recycled again and again.
GLASS RECYCLING
ALUMINIUM RECYCLINGAluminium recycling is the process by which scrap aluminium can be reused in
products after its initial production. The process involves simply re-melting the metal, which is far
less expensive and energy intensive than creating new aluminium through
the electrolysis of aluminium oxide, which must first be mined from bauxite ore and then refined
using the Bayer process.

WOOD RECYCLING
• Wood recycling is the process of turning waste timber into usable products. Recycling timber is a practice that was popularized in the early 1990s as issues such as deforestation and climate change, prompted both timber suppliers and consumers to turn to a more sustainable timber source.
