Source Reduction:: S25: Other process modifications made[-15-24%]

Methods to Identify SR Opportunities: T04: Participative team management
|
S25: Rinsewater from washouts was collected and held to be reused in future campaigns. Source Reduction - Attempted to combine campaigns to reduce washouts and waste water generation. |
| 2020 |
Source Reduction:: W58: Other process modifications[-15-24%]
|
Methods to Identify SR Opportunities: T04: Participative team management
|
W58: Rinsewater from washouts was collected and held to be reused in future campaigns. This activity was limited as the stored washwater is susceptible to bacteria growth while in storage. Source Reduction - We also attempted to combine campaigns to reduce washouts and waste water generation. |
| 2019 |
Source Reduction:: W14: Changed production schedule to minimize equipment and feedstock changeovers
Source Reduction:: W52: Modified equipment, layout, or piping Source Reduction:: W67: Improved rinse equipment design |

W14: We have 2 Clients that use Carbaryl in their formulation. We worked with both Clients and are now scheduling these production runs together to eliminate washouts between the campaigns. W52: We purchased new process tanks in 2019 that are polished stainless. This allows for much easier cleaning and reduction in rinse water generation. W67: Upgraded our high pressure washers to reduce volume of rinse water generation. |
| 2018 |
Source Reduction:: W14: Changed production schedule to minimize equipment and feedstock changeovers[-5-14%]
|

W14: Combined several runs into single campaigns to reduce washouts and rinsewater. |
| 2016 |

Source Reduction:: W68: Improved rinse equipment operation |

W19: Combined several Carbaryl campaigns together to reduce washouts. W68: High pressure washers installed to decrease waste water generation during cleaning process. |
| 2015 |
Source Reduction:: W14: Changed production schedule to minimize equipment and feedstock changeovers[-5-14%]
Source Reduction:: W71: Other cleaning and degreasing modifications[-5-14%] |
Methods to Identify SR Opportunities: T04: Participative team management

Other Environmental Practices: Recycling - Rinse water from washouts is collected and recycled back into succeeding production runs. This activity helps to reduce the amount of waste generated for the year. |

W71: We modified the cleanout procedure to utilize high pressure washers(high pressure, low flow) to conduct cleaning of tanks and piping. This has reduced the amount of washwater generated during the cleaning cycles. Source Reduction: Recycling - We are continuing to combine campaigns of Carbaryl at our facility to minimize the number of washouts required each year. By combining 2 production campaigns into a single run, we reduce our annual cumulative waste by 10%. |

W14: Combined multiple campaigns into a single run to minimize wash water generated. W19: Held out water from the product during processing and then added it at the end to "flush" the system clean into the finished product. Simplified the cleanout and much less water was generated. |

W14: Smaller campaigns were combined into larger ones to reduce the amount of rinse water containing Carbaryl. Source Reduction - Rinse water containing Carbaryl is captured and held on-site for recycling into future campaigns. This minimizes waste sent to off-site incinerators. We also have combined runs over the year that has reduced the number of washouts. |
| 2011 | Other Environmental Practices - Carbaryl rinse water from the process is collected and used in future production runs. This minimizes off-site treatment of Carbaryl. | ||
| 2010 | Other Environmental Practices - All rinse water from the Carbaryl process is captured and held on-site in full containment areas. All of this rinse water is then consumed during the next Carbaryl campaign. The only disposal of Carbaryl to an offsite facility is the PPE(personal protective equipment) and trash contaminated with Carbaryl that is used in the processing steps. This waste is captured into drums and shipped off-site for treatment. | ||

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.

- 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")
