Frequently Asked Questions

Below are answers to questions that we are frequently asked related to our renewable natural gas or chemical recycling technologies and projects. If you have a burning question for the team that’s not answered below, feel free to drop us a note.


How does anaerobic digestion work?

Anaerobic digestion is the process by which bacteria break down organic matter like manure or food waste in the absence of oxygen, and transform that waste into biogas. In our anaerobic digestion projects, waste is collected and loaded into a digester, which creates biogas. The raw biogas is then cleaned, upgraded, and compressed into pipeline quality renewable natural gas (RNG). That RNG is either transported through a pipeline or via trucks to local pipelines, where it is injected and sold. In addition to RNG, other renewable products generated by our dairy manure anaerobic digestion projects include biofertilizer, digested dairy fiber for use as cow bedding or as a peat moss substitute, and reclaimed irrigation water.

What is renewable natural gas (RNG)?

Renewable natural gas(RNG) is natural gas produced from organic waste materials food waste and animal and plant-based material. The major sources of RNG are landfills, animal manure, and solid waste extracted during wastewater treatment. The gas is deemed “renewable” because it is created by waste that is continuously produced, and is naturally occurring as part of the decomposition process. Anaerobic digestion captures raw biogas, cleans, upgrades, and compressed it into RNG.

What is pyrolysis?

Pyrolysis is the chemical decomposition of compounds caused by high temperatures. It is the plastics renewal process by which Brightmark Energy’s chemical recycling technology breaks down plastics into their core components so that these materials can be transformed into fuels and wax or back into the raw materials used to manufacture new plastics. 

Is your technology the same as trash incineration?

No, our plastics-to-fuel recycling technology does not use combustion, as is used in trash incinerators. Our technology uses the process of pyrolysis to break the chemical bonds in plastic in the absence of oxygen (incineration/combustion requires fire/oxygen) so that the raw materials can be recaptured and transformed into other useful products, like fuels and wax or even into new plastic products. It is a circular economy technology with minimal environmental impacts.

What are the benefits of recycling?

According to the U.S. Environmental Protection Agency, the benefits of recycling include:

  • Reduction in the amount of waste sent to landfills and incinerators

  • Conservation of natural resources such as timber, water and minerals

  • Increase in economic security by tapping a domestic source of materials

  • Prevention of pollution by reducing the need to collect new raw materials

  • Saves energy

  • Support of American manufacturing and conserves valuable resources

  • Helps create jobs in the recycling and manufacturing industries in the United States

What is chemical recycling?

Chemical recycling is any process by which a polymer is chemically reduced to its original monomer form so that it can eventually be processed (re-polymerized) and remade into new plastic materials that go on to be new plastic products. Chemical recycling helps us overcome the limits of traditional recycling.

When will construction on your Ashley, IN recycling plant be complete?

We expect that construction will be complete at Brightmark Energy’s Ashley, Indiana recycling plant in late 2020.

Are you hiring for jobs at the plant?

Yes, we are now seeking passionate, hardworking professionals at all levels to work in our Ashley, Indiana recycling facility when it opens in 2020. Check out our open positions and find out more about what it’s like to work for Brightmark Energy.

Where are your current projects?

We have projects nationwide, including in Washington State, South Carolina, New York, Wisconsin, and Indiana. We are seeking partners with an interest in developing anaerobic digestion projects throughout the country.

How can we work together?

Let’s talk about it! We are seeking partners with an interest in developing anaerobic digestion projects throughout the country, including dairy farmers and wastewater treatment plant operators. We are also interested in speaking with any localities with an interest in bringing a plastics renewal facility to their communities, or acquiring our proprietary plastics renewal technology for use in an existing recycling facility.

Are you hiring?

We are always looking for passionate, hardworking energy industry professionals. Check out our open positions and find out more about what it’s like to work at Brightmark Energy.
