Module 4.51: waste reduction and recycling
Reduce, reuse and recycle: 3 R's
Source reduction: see also Tesla manufacturing: "best part of any car is the part you can delete"
also reusable containers, buying inprogressbulk for(e.g. health food store)
also reusable containers, buying in
Reuse: easiest example is shopping bags, also cups here at the elab
Recycling: can be closed loop (carpet, asphalt) or open loop (PET bottles in to garments or decking-TREX)
- Tough ones: glass and paper
- Glass needs to be melted to be reused, we don't do this in Hawaii, so there is a carbon footprint to transporting it to be recycled
- Paper is easier, but uses water to recycle, and again, has a carbon footprint for transport in Hawaii.
- Amazon boxes are a prime example...
- Composting: degrading naturally: if just paper, good for worms (e.g. Willie's garden)
- If food, can be a rodent issue (e.g. VC garden)
- Both are aerobic processes, so need to be well ventilated or "turned"
- Egg farm downhill from HPA: another example
