ROI’s New Carbon Negative Process for Woody Debris Recycling

Whilst it is currently popular to proclaim, “Reduced Carbon Footprint” or “Carbon Neutral process”, neither will have a positive impact on our environment. The only solution is that we must become Carbon Negative to combat our own emissions and developing economies emissions increases throughout the world.

There’s currently more than 52,000,000 tons of clean wood and vegetative debris entering US landfills per year, which is a clear indicator that existing clean wood and vegetative debris recycling markets are saturated. Not utilizing this valuable resource in a beneficial manner is neglectful and harmful to our environment.

Other processes only reduce the mass transforming debris into a more manageable form for transportation. Doing so increases the amount of times the material’s handled, therefore increasing the processing cost and carbon footprint when no markets are available.

Making sure a process footprint includes the entire process, not segmenting or leaving out an important step is very important to calculating the real processing carbon footprint. Composting for instance, a popular wood recycling option, requires the following steps to manufacture an end product.

ROI’s patent pending Carbon Negative Process is the only available Single-Step recycling system that reduces the processing carbon footprint to less than neutral, having a net effect of removing CO2e emissions from the atmosphere, rather than adding it. All other available processes add CO2e emissions, some much more significant than others. The CARBONATOR™ carbon negative technology properly reduces volume by approximately 90% while recycling these debris into a valuable end-product, a high-grade Biochar, which has similar properties to activated carbon. This end-product is currently used in many markets to assist with reducing other processes carbon footprint and further benefiting our environment.

The following required processing steps are large contributors of CO2e and PM emissions and therefore must be included in the processes carbon footprint.


  • Material be hauled to a composting facility
  • Material must be ground either pre or post arrival
  • Ground material needs to be windrowed
  • Windrowed material needs to be rotated or aeriated regularly
  • Windrowed material must be watered
  • Finished product must be screened
  • Overs require handling
  • Associated decomposition producing methane
  • Finished product must be bagged and palletized or loaded in bulk and hauled off site

The Importance of ROI’s Carbon Negative Process


Carbon dioxide equivalent or (CO2e) is a term for describing different greenhouse gases in a common unit. For any quantity and type of greenhouse gas, CO2e signifies the amount of CO2 which would have the equivalent global warming impact.

Carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) make up the vast majority of greenhouse gas emissions. For any quantity and type of greenhouse gas, CO2e signifies the amount of CO2 which would have the equivalent global warming impact released during the combustion of fossil fuels, such as coal, oil, and natural gas, during processing activities. A long- term sustainable solution to global warming and climate change requires that we eliminate or substantially reduce the amount of (CO2e) being emitted into the atmosphere.

What is a Processes Carbon Footprint?

The total amount of greenhouse gases produced to directly and indirectly support human activities, expressed in equivalent tons of carbon dioxide (CO2).

How is Your Carbon Footprint Calculated?

A carbon footprint is measured in tonnes of carbon dioxide equivalent (CO2e). The carbon dioxide equivalent CO2e allows the different greenhouse gases to be compared on a like-for-like basis relative to one unit of CO2.

What does it mean to Reduce Your Carbon Footprint?

Reducing your carbon footprint means that you reduce the amount of carbon dioxide that is emitted due to your daily processing activities.

Why is it important to understand a Processes Carbon Footprint?

Although greenhouse gases do occur naturally, human activity contributes a great deal to greenhouse gas emissions. Your carbon footprint or your impact on the environment measures the greenhouse gases that you are responsible for creating.

Is Your Process Carbon Positive, Neutral, or Negative?


What does it mean to have a Carbon Positive Process?

(your process adds to atmospheric carbon buildup) Emitting sequestered carbon into the atmosphere. For example, using carbon-based resources such as coal, crude oil and natural gas that have been sequestered in the earth for millions of years and emitting the carbon into the atmosphere.

What does it mean to have a Carbon Neutral Process?

(The level of atmospheric carbon does not change through your process) Taking plant-based carbon removed from the atmosphere through the process of photosynthesis and emitting this carbon back into the atmosphere. For example, the carbon emitted from the burning of trees back into the atmosphere. (the fossil fuel energy used to cut the wood debris and handle, are all carbon positive.)

What does it mean to have a Carbon Negative Process?

(your process causes a reduction in atmospheric carbon) Processing plant-based carbon that originated from the atmosphere through photosynthesis and sequestering the carbon by converting to biochar. For example, biochar is created from the carbonizing of biomass and sequestering the biochar (carbon) in agricultural soils. (Additional neutral benefits can be increased based on biochar applications. In an agricultural use, offsetting chemical fertilizer use further increases the processes carbon negative attributes.)
