To many experts, it makes more environmental
and economic sense for households and businesses
to separate their trash into recyclable categories such
as glass, paper, metals, certain types of plastics, and
compostable materials. This source separation approach
produces much less air and water pollution and costs
less to implement than MRFs cost. It also saves more
energy, provides more jobs per unit of material, and
yields cleaner and usually more valuable recyclables.
In addition, sorting material educates people about the
need for recycling.
