Why is there a need to recycle?

Saves natural resources Minimize material usage

Saves energy Recycling of aluminum takes 95% less energy than new

aluminum from bauxite ore.

Saves clean air & water Reduces carbon emission (Kyoto Protocol)

Saves landfill space Materials that go into recycling do not go into incinerator and

landfill

Soda Blasting

Sodium bicarbonate appliedagainst a surface using compressedair.

Non-destructive method

(Cleaning, paint stripping, andetc.)

Does not harm the substrate.

Does not produce heat on surface,avoid warping.

Can be used on plastic, metal,glass
