Computer Disposal

Waste management is a major issue with millions of computers being disposed of every year. Here are some tips to help the environment.

1. Donate your old working computer to a school or charity. They might be able to keep it going for a bit longer.

2. Give your non working system to a trade or electronic school.

3. Dispose of it thoughtfully to a recycling agent.

At high levels this substance can be harmful to human health and well being but the evidence as yet is not clear on how harmful it can be in causing cancer. It can cause lung disease  where people are exposed to the substance in high concentrations.

Mobile Phones

Mobile phones are very similar to larger computers, they possess the same chemical elements. The phones are not biodegradeable yet most of the substances inside can be recovered for further productive use. Recycle at your local pick up point like the one listed below to prevent harmful chemical concentrations entering the environment.
