4ft Homestead ProtaPod Grub Composter

4 Foot Prosumer ProtaPod (Body Only)

Prosumer / Homestead ProtaPod Composting System: 4 foot polyethylene bodies only. These have the bioconversion capacity of 4-5+ BioPod Plus units and can accept 20-25+ lbs per day. This special 2013-14 production run will not include the old metal stand and problematic drainage kit. If you have a source of food waste, offal or manure, you can quickly offset your purchases of store-bought feed by growing huge quantities of grubs for your chickens or fish. Self-reliance meets sustainability meets recycling meets insect farmer!

These are the original GEN I ProtaPods bodies with some drainage support enhancements - they are being made available to DIY setups in limited quantities only. They no longer include filters, collection jars, tubes, etc. We can now nest up to 10 pods on a single pallet. Use matala, perforate plates or coir fiber mats with gravel underneath to promote bottom drainage. When designing your drainage layer, use a maximum diameter of 809 mm. In order to maintain maximum flexibility with both imperial and metric plumbing fixtures, we no longer pre-drill the bottom drainage hole(s). Please call or email for a shipping quote. Each pod is 24 lbs.

Conference calls covering setup and operations are available to ProtaPod clients at no additional cost.  Comes with a 30+ page e-manual.

Divert AND recycle all residential, commercial and institutional food scraps from the municipal solid waste stream BEFORE trash collection

  • Mitigate germs and odors associated with garbage receptacles by diversion of scraps into pod
  • Remaining recyclables in waste stream have lower levels of contaminants due to separation of organics, thus improving overall recycling rates and waste diversion ratios
  • Keeps critters out of backyard compost bins and trash receptacles by removal of kitchen waste
  • Eliminates the need for insinkerators while decreasing the quantity of organic biosolids that must be processed at water treatment facilities
  • Reduces anaerobic decay in landfills, the primary source of anthropogenic methane, a greenhouse gas 20+ times more potent than CO2
  • Saves energy and lowers the carbon footprint by decentralizing waste pickup


Significant reduction of fresh manure and carcasses in both volume and weight at commercial livestock operations

  • Recapture valuable proteins & lipids as renderable, self-separating biomass
  • Low cost production of sustainable aquaculture / aquaponic feed without depletion of pelagic ocean fisheries
  • Nutritional food for most varieties of domesticated poultry
  • Enhances backyard habitat for insect-loving migratory song birds using specialty feeder
  • A live, high quality supplemental food rich in calcium that is ideal for herps and ornamental fish
  • Live grubs may be supplied to regional bait shops for resale to anglers
  • Friable compost high in cellulose easily transformed by vermiculture into lucrative worm castings or utilized raw as a value-added soil amendment
