Designing Out Waste in Dry-Type Transformer Manufacturing

In dry-type transformer manufacturing, the standard use of epoxy resin generates significant waste, with industrial drums typically discarded as hazardous material after a single use.

At Daqo Transformer, we saw an opportunity to redesign this process – reducing waste without compromising product quality or performance.

In collaboration with our resin suppliers, we implemented a closed-loop return-and-reuse system for epoxy resin drums. After each use, drums are collected, professionally cleaned, rigorously inspected, and reintroduced into production under strict safety and quality protocols.

To ensure full transparency and control, each drum is digitally tracked throughout its lifecycle via mobile and web-based platforms. Reuse is only authorized after meeting predefined inspection criteria, guaranteeing consistency and operational safety.

Measurable impact from a practical initiative

This systematic approach has delivered clear, quantifiable results:

• More than 1,300 industrial drums avoided from disposal each year

• Over 20 tons of hazardous waste eliminated annually

• Zero impact on transformer performance and production efficiency

Recognized as a regional benchmark for zero-waste industrial practices, the program is now promoted locally as a reference model for sustainable manufacturing.

By embedding waste reduction into everyday operations, Daqo Transformer demonstrates how sustainability can be practically and systematically integrated into manufacturing – delivering controlled, repeatable, and measurable environmental and operational benefits.
