IN-VESSEL ODOUR AND LEACHATE FREE COMPOSTING SOLUTIONS

HotRot Organic Solutions designs, builds, installs and commissions complete turnkey organic waste treatment plants. Modular, scalable equipment options are suited to new green field sites or as an upgrade/extension to an existing waste processing facility.

Specialised applications of HotRot technology provide solutions for source separated organics (SSO), sludge or biosolids; diapers (nappies) and absorbent hygiene waste (AHW) for municipalities, waste collection and processing companies and commercial and industrial organic waste producers (e.g. food processors, breweries, etc).

HotRot equipment is ideal for on-site composting of food and organic waste at zoos, universities and other institutions, remote work camps (mining and, oil and gas projects) and local communities. HotRot offers a complete integrated solution from waste collection, pre-processing and sorting, through to composting and end-product use.

HotRot plants come with a contractual odour free guarantee and a system that is simple to operate, requires minimal space, labour and maintenance. As an added benefit, HotRot plants are also leachate free.

  • HotRot Solutions

    Composting solutions for municipal source separated organics (SSO), biosolids or sewage sludge, diapers and AHP, and organic waste at remote sites.

    • High efficiency composting of kitchen and garden (leaf and yard) waste. Quality compost requires quality inputs: just as “you can’t make a silk purse from a sow’s ear”, you can’t make quality compost from mixed municipal waste. Some people will argue with this statement but HotRot stands by it.

      --END--

      It is often suggested that collecting mixed waste is cheaper and easier than collecting source separated materials (organics and recyclables) but there are a number of studies that do not support this. --END-- No matter how good post-collection separation is, organics and recyclables recovered from mechanically separated MSW will be contaminated. Any savings in collection are lost in cost and complexity of sorting equipment and reduced value of recovered materials (compost and recyclables). Traditional recycling countries (such as China) have recently (August 2013) indicated that they will stop accepting dirty plastics for recycling. To maximise value of recovered resources, municipalities should consider at least a three-bin collection system; one bin for organics (for composting), one bin of dry mixed recyclables and a third bin of residuals for landfill or alternative disposal. The three-bin system also lends itself to weekly organics collection and alternate bi-weekly collection of recyclables and residuals.

    • Innovative composting of biosolids using natural and synthetic bulkers. Sludge or biosolids composting is traditionally done off-site at a dedicated composting facility. This generally involves significant transportation, reducing overall environmental benefits. --END-- HotRot’s fully enclosed, small footprint, composting system lends itself to composting of biosolids on-site at the wastewater or sewage treatment plant. Both primary and secondary sludge can be composted but material should be dewatered or solar-thickened as much as possible. --END-- A HotRot sludge composting system can be integrated seamlessly into the operations of a wastewater treatment plant. HotRot also offers the ability to replace traditional organic bulking agents (shredded wood or garden waste) with a fully reusable synthetic bulker.

    • Reducing costs and environmental impacts at mine sites and oil and gas projects. HotRot systems have been employed at remote camps in Northern Canada, West Africa, Asia, Australia and the Pacific. --END-- Work camps at mines and oil and gas projects, or indeed large infrastructure projects, can become large self-contained communities. Their locations tend to face specific challenges when it comes to obtaining fresh fruit and vegetables and disposing of waste. --END--Remote camps often produce a disproportionately high amount of food waste per head. This waste can be difficult and costly to dispose of and represents a true resource that could be used for the supply of produce to the camp or local community or assisting with wider site restoration or reforestation.

      The HotRot technology is simple to operate, robust and uses minimal power while transforming putrescible organic waste, which is smelly and attracts vermin, to stable pleasant compost (soil-like material).

    • A complete system and business model for collection and processing of diapers and absorbent hygiene waste. More than 19 billion disposable diapers (nappies) are used annually in the US alone - enough to circumnavigate the globe more than 90 times.

      --END--

       While diapers and absorbent hygiene waste (AHW) do contain plastic and other non-compostable materials a large portion is organic. The super absorbent polymer (SAP), which makes up more than 30% of a fresh diaper, was initially developed by the US Dept. of Ag. as an additive to improve the moisture holding capacity of soils and is commonly used in commercial composts such as potting and tub mixes. --END--

      Alternative diaper recycling systems have relied on deconstructing the diaper and recovering materials for recycling. They have relied on complex machinery and thus have required large quantities of diapers and AHW to be economic. HotRot offers an economic scalable commercial solution that is suitable for global use.

    • Compact composting systems for processing organic waste on-site. The ability to compost organic waste on site and then utilise the compost produced offers organisations such as zoos, universities and specialist processors (e.g. breweries) the ability to truly close-the-loop.--END-- On-site composting is the most efficient form of organic waste recycling, eliminating greenhouse gas emissions from waste transportation and haulage and traditional disposal such as landfill. --END--Composted material can be used for landscaping or crop production: HotRot client Sierra Nevada Breweries grows vegetables for its own on-site restaurant and uses compost on an organics hops field as part of a closed loop philosophy.
