Table 324 Operating Costs And Savings Associated With Waste Minimization Projects

Reduced waste management costs

This reduction includes reductions in costs for: Offsite treatment, storage, and disposal fees State fees and taxes on hazardous waste generators Transportation costs

Onsite treatment, storage, and handling costs Permitting, reporting, and recordkeeping costs

Input material cost savings An option that reduces waste usually decreases the demand for input materials. Insurance and liability savings A waste minimization option can be significant enough to reduce a company's insurance payments. It can also lower a company's potential liability associated with remedial cleanup of treatment, storage, and disposal facilities (TSDFs) and workplace safety. (The magnitude of liability savings is difficult to determine).

Changes in costs associated with quality

A waste minimization option may have a positive or negative effect on product quality. This effect can result in higher (or lower) costs for rework, scrap, or quality control functions.

Changes in utility costs Utility costs may increase or decrease. This cost includes steam, electricity, process and cooling water, plant air, refrigeration, or inert gas.

Changes in operating and maintenance labor, burden, and benefits

An option can either increase or decrease labor requirements. This change may be reflected in changes in overtime hours or in changes in the number of employees. When direct labor costs change, the burden and benefit costs also change. In large projects, supervision costs also change.

Changes in operating and maintenance supplies

An option can increase or decrease the use of operating and maintenance supplies.

Changes in overhead costs Large waste minimization projects can affect a facility's overhead costs.

Changes in revenues from increased (or decreased) production An option can result in an increase in the productivity of a unit. This increase results in a change in revenues. (Note that operating costs can also change accordingly.)

Increased revenues from by-products

A waste minimization option may produce a by-product that can be sold to a recycler or sold to another company as a raw material. This sale increases the company's revenues.

single, dramatic implementation, but by a series of small improvements implemented over time. Therefore, the last step is to renew the program.

Waste assessment should be documented as simply as possible. Capturing waste reduction ideas that were proposed and rejected may be useful in future iterations of the program. However, writing reports is not necessary.

Meeting minutes and worksheets used for analyses can be structured in such a way that merely collecting them in a folder is enough documentation.
