Metal Chip Recycling Case Study: How a Mexican Manufacturer Reduced Costs & Passed Environmental Audits

Explore our metal chip recycling case study: A pump manufacturer in Mexico reduced costs, recycled coolant, and passed audits with the help of a custom briquetting line.

In metalworking, machining processes generate large amounts of metal chips (swarf) — often accounting for up to 20% of the raw material. These chips not only take up valuable space but also leak cutting fluids, leading to environmental audit failures and high disposal costs.

This metal chip recycling case study highlights how XX Company in Chihuahua, Mexico, adopted a swarf briquetting line to solve oil leakage, improve recycling profits, and meet sustainability goals. Here’s a breakdown of the challenges they faced and how our solution delivered results.

【Customer Challenges: Space, Cost, and Environmental Compliance】

The customer, a long-established Mexican pump manufacturer, faced four major challenges:

Challenge 1: Recycling Long Iron Swarf

Monthly volume: 20–30 tons

Needed: 1–2 tons/day capacity

Goal: de-oiling + briquetting for furnace charging

Problem: loose piles of iron chips occupied valuable floor space

Challenge 2: Nickel-Containing Cast Iron Chips

Nickel content: 18%

Monthly volume: 12–16 tons

Needed: production briquetting line by March 2026

Challenge 3: Copper Chips with High Coolant Content

Monthly volume: 5 tons

Problem: direct melting produced heavy smoke & frequent filter changes

Needed: copper chip de-oiling + briquetting

Challenge 4: Engine Block Crushing

Size: 1400 × 965 × 1240 mm

Weight: 1343 kg/unit

Monthly processing: 300–400 tons

Goal: crushing + impurity separation with a large engine crusher

【Our Metal Chip Recycling Solution: A Fully Automated Line】

We engineered a modular metal chip recycling solution, combining multiple machines into one swarf briquetting line:

Chip Crusher – breaks long tangled swarf into manageable fragments

Centrifugal De-oiler (Coolant Recycling Machine) – reduces residual oil to <5%, recovered for reuse

Metal Chip Briquetting Machine – compresses loose chips into dense, furnace-ready briquettes

Coolant Recovery & Filtration Unit – filters and reuses cutting fluids, prevents secondary pollution

AGV Loader – automates chip loading/unloading, reducing manual labor

(Image ALT example: “Centrifugal de-oiler processing copper chips in Mexico factory”)

【Measurable Results and Cost-Saving Benefits】
1. Slashed Storage Needs and Logistics Costs by 90%

Compression ratio: 10:1

Reduced storage footprint by 90%, lowering transport expenses

2. Boosted Recycling Revenue by $150–450 per Ton

Briquettes sell at a premium compared to loose chips

Increased profitability from recycled materials

3. Saved Tens of Thousands Through Coolant Recycling

Cutting fluids filtered & reused

Significant reduction in annual coolant purchase costs

4. Passed Environmental Audits with Zero Leakage Issues

Leak-free briquettes, no oil spillage

Smooth compliance with strict regulations

5. Enhanced Furnace Efficiency & Metal Yield

Briquettes melted faster with less oxidation

Higher metal recovery rates and lower energy consumption

Why They Chose Us: Engineering Expertise in Action

Our engineering team conducted a complete waste stream audit:

Identified chip types & monthly volumes

Calculated ROI for de-oiling + briquetting

Designed a custom line layout adapted to their facility

Delivered a turnkey system with Schneider PLC controls and premium components (Siemens motors, Rexroth hydraulics)

This ensured a low-maintenance, high-reliability solution, customized for the customer’s long-term success.

【Customer Feedback】

“Before, swarf piles took up valuable space, and disposal costs were high. Now, iron and copper chips are processed daily, oil is recycled, briquettes go straight into our furnace, and profits are up. Best of all, we passed our environmental inspection without issues.”
– Operations Director, XX Company
