Plywood scarp may be used for low cost furniture . However small plywood pieces or damaged plywood due to environmental effects are also available in large quantities creating problems of disposal. It can be used as fuel. But it is not environment friendly.
It is not easy to find a broad spectrum recycling focus paper about plywood. Maybe this thesis and its references will help: https://www.theseus.fi/bitstream/handle/10024/117719/Salmela_Miisa.pdf?sequence=2&isAllowed=y
Please note that plywood scrap should never be used as fuel in household or domestic heaters and appliances. It may contain glue and other chemicals that are toxic to human beings. It is ok to use as RDF in cement plants and power generation plants.
Plywood scraps can be recycled into recycled plywood. An outline of the process is at the link below.
Crushing of waste wood and used recycled plywood:
- Clamps, bolts, chains, etc. are removed from waste wood.
- The waste wood or used recycled plywood is crushed into wood chips 30 to 50 mm in size.
- Through magnetic separation and metal detection steps, nails, staples, stainless steel, aluminum foil and other foreign matter are removed.
- Wood chips are further crushed into smaller chips.
- Used recycled plywood crushed into wood chips is processed by a defibrator into wood fibers...
Production of recycled plywood:
- The center layer of plywood is formed from a mixture of wood chips and plastic flakes.
- The surface layers of plywood, which cover the center layer, are formed from a mixture of wood fibers originating from recycled plywood and plastic fibers.
- The mixture of wood material and plastics is heated and pressurized to form plywood (by hot pressing forming).
- The formed plywood is cooled and cut to specified sizes.

Tank you. Very interesting. Pity the end-product was not profitable.
