Making a Difference with Xerochem

Challenge
A large U.S. manufacturing facility generated recurring volumes of spent sulfuric acid that were historically neutralized on-site and discharged through routine wastewater operations. This approach required significant labor, reagent consumption, and ongoing treatment infrastructure, resulting in elevated monthly operating costs and limited operational flexibility.

Our Approach

• Performed an independent materials viability review of the sulfuric acid stream
   
• Evaluated compatibility with secondary industrial reuse markets
   
• Coordinated laboratory screening and downstream acceptance requirements
   
• Developed transportation criteria to enable off-site redistribution
   

Outcome

• Transitioned the stream from on-site neutralization to off-site reuse
   
• Reduced total program cost by approximately 50%
   
• Eliminated labor-intensive treatment steps
   
• Established a repeatable reuse pathway with long-term scalability

Challenge
A U.S. manufacturing facility generated recurring volumes of phosphoric acid that were historically shipped in intermediate bulk containers for off-site treatment. The program required complex logistics coordination and resulted in elevated monthly disposal expense.

Our Approach

• Conducted an independent materials viability review of the phosphoric acid stream
   
• Evaluated reuse pathways aligned with neutralization and secondary industrial applications
   
• Coordinated analytical review and downstream acceptance requirements
   
• Developed a transportation framework to support consistent off-site reuse
   

Outcome

• Converted a legacy disposal program into a beneficial-reuse pathway
   
• Reduced monthly program cost more than 70%
   
• Eliminated RCRA classification for the material stream

Challenge
A U.S. manufacturing facility accumulated multiple tanker loads of surplus hydrogen peroxide used in a passivation process. The incumbent waste vendor was unable to identify viable transportation or cost-effective management options, placing the project at risk of extended on-site storage and significant unplanned expense.

Our Approach

• Performed an independent materials viability assessment of the surplus oxidizer
   
• Identified multiple qualified transportation providers
   
• Evaluated reuse and secondary market redistribution pathways
   
• Coordinated technical acceptance between generator, carriers, and end-users
   

Outcome

• Avoided landfill disposal previously estimated at approximately $440,000
   
• Implemented a redistribution solution that reduced total project cost to approximately $42,000
   
• Eliminated extended on-site storage risk
   
• Demonstrated the value of market-based materials strategy over traditional disposal

Challenge
A U.S. specialty chemicals manufacturer generated hydrochloric acid as a routine byproduct and historically managed the stream as hazardous waste through off-site treatment. This approach required manifesting under RCRA and resulted in regulatory burden with limited operational flexibility.

Our Approach

• Conducted an independent materials viability review of the hydrochloric acid stream
   
• Evaluated secondary industrial reuse applications aligned with reagent-grade tolerance ranges
   
• Coordinated technical acceptance with downstream processing facilities
   
• Developed a non-hazardous shipping framework to support beneficial reuse
   

Outcome

• Transitioned the material from RCRA hazardous waste to beneficial reuse
   
• Enabled shipment under bill of lading rather than hazardous waste manifest
   
• Maintained program cost parity while reducing regulatory exposure
   
• Improved long-term outlet stability through reuse integration
