Basics
- This page aims to outline the development of a workflow for the Production, Storage, and Use of Refuse Derived Fuel at a small scale
- Although somewhat similar to Small Scale Waste Incineration , this page aims to mainly use only clean burning materials
- Also care to optimize use as fuel is prioritized over maximizing Variety of MSW it can process/efficiency
Equipment
Fuel Preparation
- Paper Shredder (Preferably one that cam handle a full sheet of Corrugated Containerboard )
- A Paper Pulping Setup
- A Bin, Water, and an Immersion Blender or Drill Bit Attachment should work fine, although more complex setups may be worth looking into
- Potentially a Moisture Content Meter
- Additives/Binders such as Starch
- Scissors / a Reciprocating Saw if cutting pre-shredding is needed, or in leu of a shredder
- Final Pressing Equipment for the Prepared Fuel Mixture Such as
- A Paper Log Press or Paper Briquette Press
- Easiest to acquire, especially if a manual device is used, also heavily proven to not be picky)
- A Pellet Mill / Pelletizer
- Higher Quality End Fuel, although requires more precise control of Moisture Content and Particle Size / Mesh Size
- A Boilie Roller / Automatic Boilie Maker
- There doesn’t seem to be any examples of this being attempted, but using a similar consistency mix, but for fuel instead of Fishing Bait may work well
- This could get a form factor similar to Wood Chips or Wood Pellets , but less picky in fuel properties
- This would almost certainly require usage of a Binder however
- A Paper Log Press or Paper Briquette Press
- A Solar Solid Fuel Dryer would be of use, although not required
- Torrefaction or Charring into Charcoal may also be useful
Fuel Use
- It could be used for a Fire Pit, although use for Heating to Electricity Generation is preferable
- A Rocket Stove , Rocket Mass Heater , Thermoelectric Stove are all good lower cost options
- Gasification could be done
- Using the Charcoal Gasifier , assuming it can run on the fuel shape, would be doable given the TRL of that design
- Entrained Flow Gasification of the slurry itself would be an interesting route to explore
