How To Reduce Waste In Construction
Waste can be reduced simply by using no more than is needed. This can take careful planning to execute properly, but committing to a mindset that is intentional about how material is used and in what amounts is an essential starting point. It's impossible to not create any waste, so do your best to reuse it.
