Sustainable Egg Tray Program — European Retail Chain
Client Background
A leading European supermarket chain with 800+ locations across Germany, Austria, and Switzerland. The client was phasing out EPS foam egg trays across all private-label egg products to meet 2025 sustainability commitments and comply with the EU Single-Use Plastics Directive.
Challenge
- Replace 12 million EPS foam egg trays per year with a compostable alternative at cost parity
- Match existing automated packing line specifications (stack height, weight tolerance, dimensional precision ±0.5mm)
- Achieve EN 13432 industrial compostability certification within 90 days
- Maintain egg protection performance — zero increase in transit breakage rate (baseline: 0.3%)
Our Solution
- Material: Recycled newspaper pulp with food-grade water-resistant coating — fully compostable, cost-competitive with EPS at volume
- Design: Custom 10-egg tray mold developed from client CAD specifications; 3-round sampling completed in 18 days
- Production: Dedicated production line with 1.2M trays/month capacity; in-line QC at pulp mixing, forming, drying, and finishing stages
- Logistics: Nestable design reduced shipping volume by 40% vs EPS trays; FOB Shenzhen, consolidated ocean freight to Hamburg
Results
- 100% EPS replacement: All 12M trays/year transitioned to molded pulp within 4 months
- Cost neutral: Unit cost within 3% of EPS after volume scaling — offset by reduced waste disposal fees for the retailer
- Certification: EN 13432 certified in 72 days — 18 days ahead of schedule
- Breakage rate: 0.28% — actually lower than EPS baseline (0.3%) due to improved cushioning geometry
- Ongoing: Program expanded to 6-egg and 4-egg tray variants; now at 18M+ trays/year

Custom Molded Pulp Inserts — North American Electronics Brand
Client Background
A mid-size consumer electronics brand based in California, shipping 250,000+ units/year of smart home devices. Their existing packaging used die-cut EPE foam inserts — effective but non-recyclable and increasingly penalized by retailers with sustainability scorecards.
Challenge
- Design molded pulp inserts that match EPE foam's drop-test performance (ISTA 1A, 30-inch drop)
- Fit within existing outer box dimensions — zero change to downstream packaging or warehouse workflow
- Achieve per-unit cost within 10% of EPE foam at 250K annual volume
- Integrate with automated insertion equipment running at 45 units/minute
Our Solution
- Design: Engineered ribbed structure with variable wall thickness (1.5mm–3.0mm) for targeted impact absorption; 5 rounds of drop-test iteration
- Material: High-strength recycled kraft pulp blend with anti-abrasion surface treatment to protect device finish
- Production: 4-cavity mold for parallel forming; 80,000 units/month with 15-day lead time
- Testing: ISTA 1A certified by third-party lab; 100% pass rate on 30-inch flat drop, edge drop, and corner drop
Results
- Drop-test performance: Passed ISTA 1A on first submission — zero device damage in 30-sample test
- Cost: 7% above EPE foam at initial 250K volume; projected to reach parity at 500K+ with mold amortization
- Retail impact: Client's sustainability scorecard improved by 18 points, qualifying for preferred shelf placement in a major US retailer
- Ongoing: Now running 3 device SKUs; exploring molded pulp outer packaging for the next product generation
