Sustainable Use of Wood Fiber, ECO-CERTIFIED

Solidium MDF is one of the most environmentally responsible building materials available to design and construction professionals, product manufacturers and consumers.


Made almost entirely of residual by-products produced from the manufacture of Southern Pine lumber, Solidium panels are a true demonstration of sustainability.

In fact, the Del-Tin Fiber, El Dorado, Arkansas, manufacturing facility that produces Solidium is certified to the Eco-Certified Composite (ECC) Sustainability Standard CPA ECC 4-11. Developed by the Composite Panel Association (CPA), the ECC Sustainability Standard is voluntary and designed to recognize manufacturers who practice responsible wood fiber management.

Certification requires meeting a rigorous set of comprehensive environmental qualifications to use the program grademark. Verification is accomplished by an on-site facility audit, ongoing record-keeping and annual follow-up audits.

Formaldehyde Emissions STEP ONE

The first qualification for certification specifies that panels produced must comply with the California Air Resources Board (CARB) Airborne Toxic Control Measure 93120 with regard to formaldehyde emissions.

All Solidium products meet this requirement and are included in one of these categories listed on our ECC certificate:

  • Thin Medium Density Fiberboard – M12 Product Category (CARB Phase 2)
  • Medium Density Fiberboard – M22 Product Category (CARB Phase 2)
  • CARB Executive Order – No Added Formaldehyde (NAF) – N-10-082

Sustainability Standards STEP TWO

In addition to CARB compliant formaldehyde emissions, certified production facilities must meet at least three of these environmental qualifications:

  1. Carbon Footprint – requires that the cradle-to-gate carbon footprint of panels manufactured at the facility be offset or smaller than the value of the carbon stored in the panels stated in terms of kg-CO2 equivalents of greenhouse gas (CHG) emissions and calculated by using the CPA Carbon Calculator. Our Solidium-manufacturing facility meets this qualification.
  2. Local and Renewable Resource – requires a minimum of 85% of the total of all annual wood fiber used by the facility to be sourced no further than 250 miles from the production facility. Our Solidium-manufacturing facility meets this qualification.
  3. Recycled/Recovered – requires the use of at least 75% of recycled or recovered fiber to manufacture panels as calculated on a percentage basis of total dry material weight. Our Solidium-manufacturing facility meets this qualification.
  4. Sustainability – requires the plant to demonstrate that at least 97% of the fiber furnish received on site to manufacture panels was either made into completed panels or other non-waste products. Percentages are to be calculated in terms of total dry material weight. Our Solidium-manufacturing facility meets this qualification.
