Markets

Land Clearing/Forestry Debris

Land clearing generated forestry debris are often ground and trucked off-site when a strong enough beneficial use market exists. When no markets exist, these forestry debris present a liability, being left to decay.

ROI’s ENVIROSAVER™ AND CARBONATOR™ can easily carbonize whole unprocessed debris such as tops, logs, brush, slash, and stumps right on site. The end product of the carbonization, biochar, can be applied back into the soil from which the forestry debris were cleared. This enhances the quality of the forests’ soil, promoting quicker reforestation by creating a simple carbon negative process.

Municipal Yard Waste

Throughout the world, green vegetative organic material like brush and leaves is buried in landfills whole or after being processed through grinders. This organic material takes up valuable landfill space which breaks down to biogas containing methane. If not captured, this potent greenhouse gas contributes to global warming.

With ROI’s ENVIROSAVER™ and CARBONATOR™, green vegetative organic material is easily converted into a beneficial end-product that can be sold or used on-site. This will greatly increase the overall quality of other recycled products such as topsoil and compost, and can also be used at landfills to assist with odor control.

Construction and Demolition Waste

Similar to yard waste, construction and demolition waste is often deposited in landfills. For example, the US Environmental Protection Agency (EPA) estimates that the United States generates more than 135 million tons of construction and demolition waste annually. This makes C&D the second largest component in the US waste stream.

The EPA has determined that after all other recycling means have been met, there is still 17.3 million tons of clean wood waste entering landfills. Land clearing debris, pallets, crating materials, construction and demolition lumber waste are classified as C&D waste because of its limited value and lack of beneficial use markets.

Utilize an ENVIROSAVER™ or CARBONATOR™ to reduce overall volume while converting this waste stream into a marketable end-product. ROI’s air curtain burner equipment helps facilities generate an additional revenue stream from debris.

Primary & Secondary Mill Residues

ROI’s ENVIROSAVER™ 400 with its Fine Debris Hopper/Feeder System provides mills the ability to convert or even eliminate debris such as bark, chips, and sawdust- utilizing the material as its one and only fuel source for carbonization.

The ENVIROSAVER™ 400’s large hopper for bulk feeding and automatic feeder provide operators time to tend to their other tasks around the yard while the ENVIROSAVER™ is operating.

Other larger materials such as slash and unprocessed logs and stumps can be disposed of by loading directly into the combustion chamber of the ENVIROSAVER™ 400 when the hopper/feeder system is not being used.

Agriculture

Through increased regulation restricting and even outlawing open burning in some regions, along with more advanced farming techniques over the last few decades, there has become an increased volume of organic waste. Because of the ENVIROSAVER and CARBONATOR’s design features debris from the harvesting process of vineyards, cotton, fruit, and nut tree waste can now be converted in to biochar, offsetting or even eliminating in very high fertilizer costs.

ROI’s track mounted systems with automatic biochar extraction gives our customers the ability to carbonize their crop waste in the fields, or at a centralized location. Large debris such as fruit and nut trees can be removed from the soil and placed directly in to the systems primary combustion chamber, converting entire orchards in one pass in to a high value soil additive.

Natural Disasters

Immediately after a disaster, the desire for life to return to normal as quickly as possible often results in a rapid clean-up and consolidation process. The consolidated debris represent an environmental liability that often needs to be ground and/or trucked to a landfill.

The majority of material can often be converted or eliminated right at the centralized locations, after pick-up, using our ENVIROSAVER™ and CARBONATOR™ model carbonizers.

Local, State and Federal agencies can reduce costs substantially by using our systems to convert or even eliminate disaster debris. ROI’s air curtain burners provide an environmentally-sound solution by converting a waste stream into a revenue-generating product while utilizing ROI’s carbon negative process to convert their disaster debris into biochar.

Municipal Solid Waste

Carbonizing anything other than clean wood waste should only be done as an alternative to other inferior disposal methods. Unfortunately, MSW and Construction and Demolition debris are often disposed through open burning, ocean dumping, or unsightly and unhealthy neglectful methods. It is ROI’s corporate philosophy to promote the best option through whatever methods are available, including recycling and production of high-quality Refuse Derived Fuels (RDF). However, we recognize the use of our systems, in many times, represents the only practical environmentally-improved option to current methods. We have designed and produced our systems to be extremely efficient at combusting these types of wastes.
