Waste Best Practices

Waste reduction and management

  • Foam dust
    • EPS foam dust can be recycled
    • Marko Foam densifies. Best to CNC cut with Marko
    • Firewire densifies foam dust into paver stones
    • Earth Technologies sends scrap foam to Marko Foam
    • Starboard uses molded boards, which reduces foam usage
  • Resin waste
    • T.Patterson uses drip trays to conserve resin
    • Firewire has calibrated resin mixing machines
    • Earth Technologies using vacuum bagging to reduce resin usage
    • Earth Technologies uses excess resin to make hand planes
    • Enjoy Handplanes used Re-Rez, which will allow waste to be significantly reduced in a number of ways
    • NOTES:
      • CI
        • Very hard to meter poly resin, because pumps use electricity and resin is so flammable. Is working on ways to reduce resin waste, but haven’t got it working yet.
        • Epoxy resin: very precise on the amount of resin used. Have spent the time to figure out the exact amount so that waste is minimized. Have figured out workflow that works by doing two boards at once. Uses drip trays to catch resin and further minimize waste.
  • Wood waste
    • Ventana uses scrap wood to make their boards
    • Firewire is making TT boards using scrap from prior boards
    • Wood Surf Co burns waste wood to make electricity
  • Acetone recycling
    • Which partner uses acetone recycling consistently and safely? (CI or Super?)
    • CI:
      • Uses distiller to recycle acetone. Captured “still bottoms” are hazardous waste and picked up by a special hazardous waste carrier every six months, and sold as a commodity and burned as fuel. Aaron will show me the certificate. Everyone must have an EPA waste ID number, which triggers inspection. This is a highly regulated process.
      • Acetone cleans tools: squeegee and brushes. Works on both poly and epoxy. Eats through buckets.
      • Most guys probably use one. Acetone needs to be super clean for it to work, so there would be too much waste if it wasn’t used.
