Source Reduction - Periodic inventory assessments to assure volumes on hold are reduced to minimum needed.
2017	Source Reduction:: W29: Other changes in inventory control	Methods to Identify SR Opportunities: T03: Materials balance audits	W29: Reduced standby inventory to lower volumes stored on-site. Source Reduction - Periodic inventory assessments to confirm storage volumes and maintain correct balance for meeting with production.
2016		Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.	Source Reduction: Source Reduction - Lab cleanout of old processes to lower actual chemical stock on-site in 2016. Barriers to P2: B7 - No known substitutes or alternative technologies. - Currently the oligonucleotide synthesis process and relevant R&D does not have an alternate chemical product.

TRI Pollution Prevention Glossary

The Waste Management Hierarchy

The waste management hierarchy established by the Pollution Prevention Act (PPA) guides waste generators toward the best options for managing wastes. The preferred option is to prevent pollution at its source, but for waste that is generated, the preferred management methods are recycling, followed by burning for energy recovery, treatment and, as a last resort, disposing of the waste.

Source Reduction includes activities that eliminate or reduce the generation of chemical waste.
Recycling includes the recovery of a toxic chemical in waste for reuse.
Energy Recovery includes the combustion of toxic chemicals in waste to generate heat or electricity.
Treatment includes the destruction of a toxic chemical in waste.
Disposal or Other Releases includes toxic chemical quantities entering the environment.

The PPA requires facilities to provide the following details about each chemical they report to TRI:

A breakdown of production-related waste managed. This includes all amounts of the chemical released directly to the environment or otherwise managed as waste, other than waste generated by one-time events not associated with normal production processes (e.g., fires or remedial actions).
A production ratio or activity index to provide context for reported toxic chemical quantities. For example, if a chemical is used in the manufacture of refrigerators, the production index would track the number of refrigerators produced and could be used to help gauge how much of the chemical is being released per unit of production.
Any newly implemented source reduction activities, reported using "W-codes" (e.g., "W41: Increased purity of raw materials")

Facilities may also provide optional Pollution Prevention Information describing their source reduction, recycling, or pollution control activities.
