Green Cone Solar Digester Waste Food Scraps Decompose

Green Cone: In-Ground Solar Food & Pet Waste Digester

Developed in the UK, this solar digester uses the heat of the sun to generate high internal temperatures for faster microbial activity. The chamber created by the dual cones allows for passive convection currents to continually move fresh air through the system, providing the necessary oxygen to maintain aerobic conditions, which helps to mitigate foul odors. Protected, underground basket is difficult for hungry critters or curious pets to access - but easy to empty when filled with finished compost. The system provides sufficient capacity to digest 1.5-2 lbs of food waste per day (scraps from 3-5 adults). Includes starter accelerant and compost bucket. Amazing technology!  Staff recommended

  • 4-part plastic injection molded, outer cone is UV stabilized polyethylene
  • Ingenious design utilizes solar heating in the double-walled chamber to facilitate and accelerate the aerobic decomposition process within the digestion basket (2 cm distance between inner and outer cones)
  • The temperature gradients created by the double walled solar cone generate passive air movement throughout the system, maintaining the flow of oxygen
  • Aerobic conditions encourage growth of soil microorganisms and help mitigate odors associated with anaerobic decay
  • Once deposited in the below ground digestion basket, there is no possibility for unintentional access to the food waste by human activity
  • Basket is designed with slots which commence 7.5” (19 cm) below surface of ground
  • Hinged lid at top with a turnbuckle security latch protects the 8” access hole
  • Over 90% of the waste materials added will be absorbed as nutrient-rich water by the surrounding soil
  • Beneficial micro-organisms migrate freely between the surrounding soil and basket contents
  • Nutrient-rich water escapes through the basket slots into the ground, benefiting local plant life
  • Accepts all cooked and uncooked food waste including meat, fish, bones, dairy products, vegetables and fruit
  • Unit may be used and operated year-round – even in colder latitudes
  • Diverts and average of 20-30% of waste per household from the municipal waste stream
  • Recyclables are cleaner and more easily recycled due to the lack of food contamination
  • Self-enclosed design is pet, wildlife and child resistant
  • Minimal to no maintenance required
  • Meets all known relevant health, safety and environmental legislation
  • Allows food scraps to be removed from household daily, instead of weekly, reducing the build up of garbage can odors
  • Minimizes impacts on landfills – less need for addition space, and a reduction in methane generation due to anaerobic decomposition of food waste
  • Unit should be place in that part of the garden which receives the most amount of direct sunlight
  • Except for the powder that ships with the unit, do not use chemical activators or accelerants – they may disrupt the beneficial microbe activity
  • Not recommended for patios or porches
  • Stake or secure cones with ground pegs or mounded dirt in high wind areas
  • To help improve drainage, amend heavy clay soils with gravel, soil conditioner and compost
  • The water table must be below the bottom of the black digestion basket at all times
  • This system is designed for food scraps – do not add in yard waste
  • Compost residue in underground basket should be emptied into the garden every few years
Pet Poop: 

Pet excrement may be added in moderation, provided that the user takes the necessary precautions to protect against pathogens when emptying the compost residue (wear gloves, wash hands afterwards)

What is Included:
  • Green outer cone
  • Black inner cone
  • Underground digestion basket
  • Accelerator powder - a mixture of beneficial bacteria (psychrophiles (0-30˚C), mesophiles (15–45˚C) and thermophiles (45–60˚C)) on a cereal base which helps properly seed the unit when the system is first installed
  • 4 liter compost bucket for convenient emptying of food scraps
