Garbage

Anything that costs less to dispose of than it’s worth commercially.
In many cases, these materials are the same being handled by manufacturers in the production of goods but because of supply chains, technology, and often subsidized capture and transportation industries, recyclable materials are often worth less than virgin materials. In addition, this includes only traditional financial costs and not social or environmental costs and benefits. As these costs are accounted for or offset, more material now considered garbage can become viable alteratives to virgin material.

    If life-cycle or external costs of disposal are considered, then disposal may be more expensive than re-use or recycling in many cases.
