ORDER DIRECT  (USA - 48 States Only)

WE ARE FULLY STOCKED AND SHIPPING REGULARLY:  We are keeping 2021 prices the same in 2022, 2023 and 2024 - at least for now!

SHIPPING: Units ship via Fedex Ground from North Carolina.  We will email you a tracking number as soon as the order is processed in 1-2 business days.  This includes a digester kit and Installation / User's Guide.  We ONLY ship to the lower 48 contiguous states.  

BULK ORDERS: If you have a group that can team up on the purchase a bulk quantity of these, it becomes very affordable to ship them via LTL Truck Freight when you reach a quantity of only a dozen (12).  Just reach out and we will assist with a quote.

PET POOP:  We know a lot of people use these for DIGESTING PET POOP  - we now have a Pet Waste Digester Powder Kit developed specifically to breakdown fecal waste - the menu pull down allows you to select that choice for an additional $7.  It comes with 4 oz. of powder, a special yellow lid and a different jar label so you will not get the digester jars confused.

YARD DEBRIS: Green Cones were not developed to handle yard waste and we understand you may have a lot of organic debris that needs to be composted.  We are now able to ship INSIDE the Green Cone a yard waste composter for $66 called the Compost Sak.  It is soft bodied and can be moved around from place to place.  Shipping price is not affected with the addition of a Compost Sak.

ITEMS THAT MAY SHIP INSIDE GREEN CONE:  We have a few HOMESTEAD GEAR PRODUCTS left over from our online store days that are heavily discounted.  If you want anything, please review and let us know and we can tell you if it will fit. We can send you a quick payment request and ship it with your Green Cone order for free (assuming it fits)!

COMPOSTABLE SCRAP CARRIER BAGS:  Not all food waste bags are usable with the Green Cone - these should perform well in most if not all climate zones: ECOSAFE COMPOSTABLE BAGS

PRODUCT INFORMATION

Picture
Originally developed in the UK for breaking down and composting food waste, this in-ground, solar digester uses heat from the sun to generate high internal temperatures for faster microbial activity. In addition to providing insulation, the air 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.  Depending on the year of production, these have been fabricated in Canada (Ontario), the US (New Jersey) and currently in the UK (Leeds).  Designed to operate effectively in both warm and cold climates.

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).   The Green Cone may also be used to effectively break down solid pet poop and during emergency situations, human solid waste.

PLEASE NOTE:  The top bar on the outer green cone piece is for stability during the manufacturing process.  Some have been pre-removed at the factory, while others still have them attached.  If yours comes with one, you may remove it or keep it attached - it does not affect the performance either way.  Use gloves when handling the black and green cone parts, as they have sharp inner surfaces.

DIGESTER ENZYME POWDER (US Only)

The enzymatic digester / beneficial microbe mix will assist with breaking down food waste in your Green Cone.  It is optional and absolutely not required, but it will definitely assist with the decomposition process, especially in colder climates, winter months, and soils with low microbial activity.  Specifically, the powder includes 4 principal enzyme types (lipases, anylases, proteases and cellulases) and both mesophilic and thermophilic bacteria on a cereal base (tan) or salt base (white). Both work identically.
