Reiden Emery – Toray Industries, Inc.

Biochemistry | California Polytechnic State University

WASI Project:Hazardous waste reduction and cost savings

Industry:Carbon and Graphite Manufacturing (NAICS: 335991)

Project 1: MEK tank connection

Toray ships Methyl ethyl ketone (MEK) offsite for treatment and disposal since the MEK dip tanks are not connected to the distillation unit. This incurs additional costs to the organization.

The WASI intern identified a pollution prevention project to recycle their waste MEK, reduce the amount of MEK shipped out for disposal, and nearly eliminate the amount of virgin MEK purchased. This is achieved by plumbing the MEK from the dip tanks to the distillation unit.

Using 3D modeling software, the WASI intern created a piping layout and consulted with maintenance and manufacturing engineers at Toray to ensure project feasibility. With their agreement, the intern compiled a list of necessary parts by referring to the existing n-methylpyrrolidone (NMP) dip tank connections and drawings, researching prices, and ensuring the correct parts were ordered.

Project 2: Solvent usability testing

The WASI intern established an easy test to determine the usability of the solvent in the dip tanks and to establish a solvent replacement schedule based on need.

Both the MEK and NMP dip tanks were flushed and replaced every two weeks for ease of operation.

The testing and analysis focused on the NMP tanks which became dirty more quickly.

The test measured the specific gravity of the solvent at various resin saturations, using the most difficult resin to dissolve. Measurements were taken at the operating temperature of the tanks to ensure easy replication for technicians. The WASI intern found that measuring specific gravity could be a viable option for measuring the usability of wash tanks, but further testing is required.

Project 3: Compacting hazardous waste

The WASI intern compiled data to determine if a compactor would reduce the cost of hazardous waste disposal. They looked at:

Current waste accumulation.

Shipping and disposal costs, and projections.

The cost-benefit analyses conclude that purchasing a compactor is the best course of action for reducing costs.

The company has focused on sustainable manufacturing for more than 30 years and constantly looks for better materials and ways to cut energy use and create less waste. Current manufacturing processes prioritize efficiency over the conservation of valuable materials. This prioritization cost the company a previously unquantified sum of money that could instead be invested into more environmentally and financially beneficial business practices.

Canyon Creek’s emphasis on sustainability led them to look at the large quantity of wood scraps they were generating. Wood remnants that are larger than 9 x 5.5 inches are considered “usable scrap” and are recyclable. If a wood remnant is smaller than 9 x 5.5 inches, it is considered “scrap” and is not recyclable. The “scrap” is ground up and turned into wood chips or sawdust for easier transport out of the facility. Previously, Canyon Creek sold this waste as biofuel to a papermill that is now closed, so they are trying to minimize the amount of waste and find alternate disposal options.
