Waste to Clean Energy 

Today, NuCoalTM is made from forest residues – the tops, limbs, and branches left on the ground after harvesting operations. These residues account for 15% of the whole tree after harvesting. Considered unusable by lumber mills and other processing facilities, forest residues are either left to rot on the forest floor or are collected and burned to prevent forest fires. In either case, forest residues are converted to carbon dioxide without providing any economic benefit. 


Where most forest owners see unwanted waste, we see opportunity. Forest residues can easily be collected as part of existing harvesting operations for energy purposes, creating a merchantable product for forest owners and low-cost, sustainable feedstock for the NuCoalTM process. By creating a renewable fuel from recycled wood waste, Integro maximizes environmental and economic benefits for all, such as:

Environmental Benefits

  • Cleaner, more affordable renewable energy
  • NuCoal creates dramatic reductions in greenhouse gas emissions that drive global warming by replacing coal
  • NuCoal cleans the air by eliminating harmful, coal-based pollutants such as NOx and SOx  
  • Healthier forests, fewer wildfires, and less landfilling
  • Using waste from existing industries avoids new demands on the environment

Economic Benefits

  • New markets for forest owners and farmers for waste with no previous use
  • Creates well-paying jobs in the forestry and renewable energy industries, many in rural communities
  • Increases energy security by reducing dependency on foreign fossil fuels
  • New export markets to Europe, where demand is greatest
  • Coal-fired power producers benefit from the lowest-cost, least capital intensive renewable solution available today

Sustainability Policy

Forest residues are the single largest source of biomass available for new uses today. In the southeastern U.S., tens of millions of tons of forestry residues can be economically recovered and sustainably used. Integro turns this wood waste into an environmentally beneficial fuel by adhering to strict standards of sustainability and requiring our suppliers to do the same.

Integro is committed to

  1. Sourcing our feedstock from forest owners who sustainably manage the quality of the air, water, and land,
  2. Maximizing the use of forestry waste whenever economically possible and using other sustainable feedstock as needed,
  3. Locating in areas where feedstock growth rates exceed drain rates after taking into account our operations,
  4. Locating in areas where at least 5 times as much waste is available than is presently used,
  5. Frequently evaluating our sustainability practices to ensure we create the greatest environmental benefit possible, and;
  6. Regularly performing third party environmental audits of our operation and those of our suppliers.
