Questions

What’s the difference between Biogas and RNG?

BIOGAS is a biofuel which is produced when organic matter breaks down. When organic matter decomposes it releases BIOGAS comprised of roughly 40 percent carbon dioxide and 60 percent methane. The BIOGAS can be captured and used to create heat and electricity. It can also be purified and processed to remove the carbon dioxide into bio methane, also known as renewable natural gas (RNG).

RNG is a highly refined BIOGAS which is interchangeable with fossil natural gas in most applications.

Does BIOGAS use existing natural gas infrastructure?

BIOGAS cannot be added directly to natural gas infrastructure, however refined products like RNG can be added to traditional pipelines and infrastructure for use by residential and commercial customers for heat, electricity or anything natural gas is used for. Nothing changes for consumers. All natural gas powered appliances can use RNG.

What makes BIOGAS Carbon Neutral?

BIOGAS is carbon neutral because it uses methane which would have otherwise been released into the natural environment. The combustion of BIOGAS and RNG releases biogenic carbon dioxide which is the carbon absorbed from the atmosphere as organic material grows. This means the process is not increasing the overall carbon dioxide concentration in the atmosphere..

How can BIOGAS benefit my industry?

BIOGAS can help you meet your carbon reduction strategies and also assist with meeting your corporate sustainability mandates. BIOGAS is a locally sourced, low-carbon solution for industry and municipalities that generates on-site renewable energy while improving organic waste management in a closed loop process.

Is BIOGAS used in place of fossil fuels?

Refined products like RNG are chemically identical to fossil natural gas. RNG can supplement fossil fuels as a source of heat or for electricity generation and heat. RNG is a product added to existing natural gas pipelines to supplement the supply and to reduce the carbon intensity of conventional natural gas.

How does BIOGAS affect GHG and climate change?

BIOGAS reduces GHGs and addresses climate change in two ways. First, BIOGAS products provide a method to capture methane which would have otherwise been released into the atmosphere untreated. It is important to address methane emissions because methane is 84 times more potent than carbon dioxide over a 20-year period. Second, the methane captured in the form of BIOGAS is used as a renewable fuel and displaces the consumption of fossil fuels.

What are the environmental impacts of BIOGAS?

There are many environmental benefits from BIOGAS processes. BIOGAS is generated from organic waste and diverting organic waste from landfills preserves space in municipal landfills that extends their lifespan. The organic waste is usually processed close to the point of generation with the nutrients and clean energy being directly utilised by the local communities, boosting the economy and ensuring sustainability.

What can BIOGAS be made from?

BIOGAS is created from organic waste including agricultural waste, residential and commercial food processing waste, wastewater treatment plant materials, landfill waste and other select organic materials.

How much BIOGAS is created from waste?

The anaerobic digestion process can divert thousands of tonnes of organics from landfills to create energy. There will always be inputs to create BIOGAS because it is created from organic waste routinely produced from industry and households.
