A lithium battery recycling facility processing contaminated materials achieved safe, reliable emissions destruction and substantial energy savings by implementing Epcon’s high-capacity Direct-Fired Thermal Oxidizer (DFTO) with multi-stage heat recovery. The system is engineered to manage highly variable VOC emissions while reclaiming waste heat for process reuse, securing regulatory approval, and improving overall operating efficiency for this fast-growing sector.
Lithium Recycling – Thermal Treatment & VOC Abatement with Heat Recovery
Executive Summary
Project Overview
As lithium battery recycling expands to meet global demand for recovered materials, recycling facilities must manage complex, variable emission streams while controlling operating cost. A lithium recycling operation required thermal systems capable of treating VOC-laden exhaust from contaminated materials processing while meeting strict environmental requirements. The facility also sought a solution that improved energy efficiency, as thermal treatment and emissions control represent a major portion of operating expense.
Epcon engineered a DFTO solution designed for variable loads, safe operation, and heat recovery-driven efficiency.

The Challenge
Recycling operations often process changing material inputs, which can cause significant variation in VOC concentration and flow. The facility faced several critical issues:
- Managing significant variation in VOC concentration and flow from changing material inputs.
- Emissions systems needing to remain stable and compliant through these swings while maintaining safe operation.
- High energy demand, requiring an energy-optimization strategy to reduce fuel consumption.
- Need for an overall solution to support regulatory approval and long-term reliability.
The Solution
Epcon engineered a high-capacity Direct-Fired Thermal Oxidizer with multi-stage heat recovery, designed to treat variable VOC streams while reclaiming energy for process reuse.
