PRODUCING BIODEGRADABLE MATERIAL

These are materials that are

broken down through natural

biological processes

slide3

Biodegradation is the chemical breakdown of materials by a physiological environment

Plastic bags: 12 a 20 years. Cristal bottle: cerca de 4000 years. Wooden socks: 1 a 5 years. Orange peel: 6 months. Banan peel: 2 a 10 days. Roap: 3 a 14 months. Milk boxes(Tetra PACK): 5 years. Wooden sticks: 2 a 3 years.

re use
RE-USE

It´s to use an item more than once

(for the same function or for a new function)

RE-USING

Advantages:

  • Save money
  • Save energy
  • Save resources
  • Reduces disposal needs
  • Disadvantages:
    • Requires cleaning and transportation
    • Products need to be more durable
    • Some products need to be less energy efficient ( infant auto seats)
recycling
RECYCLING

Recycling differs from reuse in that it breaks

down the item into raw materials which are

then used to make new items, as opposed to

reusing the intact item.

For all these we think that the

way to go is:

producing biodegradable material
