How can you minimize the carbon emission

how can you minimize the carbon emission in your machine.

I think optimizing the right power for each machine, I have seen lot of people using 2.2 kw motor for shredder that is really too much.

You could use thin materials such as plastic bags directly into barel press or heat press.

Thank you for your suggestion fabirihotmail-com . But what if our goal is to have a portable machine for plastic heat press without using shredder? Do you have any idea ?
