Environment

Belleson takes every effort to reduce waste and be environmentally friendly:

  • We use RoHS components
  • We use lead free solder
  • We reuse shipping boxes
  • We reuse packing material, bags and other "one-time usage" items
  • We return plastic component tubes to distributors (even though they say don't)
  • We use biodegradable material where possible

If you receive your regulators in a box or envelope that has had a label removed and another added, you can feel good knowing you just helped our future generations a tiny bit.
