What’s the Difference Between Biogenic and Non-Biogenic CO2
To be able to report biogenic CO2 how to measure it.
? , operators must understand The current net increase of atmospheric CO2 is mainly due to
the combustion of fossil fuels (non-biogenic carbon) because its carbon was not part of the Earth’s carbon cycle before it was combusted.
On the other hand, biomass carbon (biogenic carbon) is part of the natural carbon cycle. The combustion of biomass material (including forest-derived and agriculture-derived feedstocks) does therefore not result in a signifi cant net increase of atmospheric CO2
if new biomass is grown again. carbon cycle.
Biogenic carbon offers signifi cant advantages over non- biogenic carbon. Using biomass as a fuel helps maintain a constant level of carbon in the environment. Its emissions remain part of the biogenic carbon cycle. Therefore, biogenic CO2
plays an important role in balancing Earth’s natural By differentiating between biogenic and non-biogenic-CO2
operators can effectively quantify GHGs, and the credits needed to offset carbon footprint.

There has been an increasing interest for the quantifi cation of biogenic CO2
When combusting mixtures of fuels which originate from fossil fuels (including plastics and textiles combusted in EfW plants), and biogenic (food waste or organic origin), current
technology prohibits the exact ratio of biogenic and fossil CO2 in the total CO2
that is emitted through the stack gas. Three Possible Approaches
1. Waste Sampling – Currently used at many EfW sites for contractual and Ofgem purposes but this method isn’t pleasant for workers having to manually pick through various waste. This approach is time consuming, and some would argue that results aren’t fully representative of the sample.
2. Software Based Approach – The software helps customers to improve their environmental performance by quantifying their greenhouse gas emissions. It calculates various parameters including CEMS data and relies on the difference between O2
determines the biogenic content of the waste and proportion of biogenic CO2
consumption and CO2 from the plant.
3. Extractive Onsite Sampling – Samples are collected from the automated sampler, processed, and sent to a laboratory that undertakes carbon-14 spectrometry.
The robust and reliable sampling method is becoming increasingly popular with EfW operators because the continuous sampling technique is fully representative of the feedstock and therefore, produces consistent results.
The results provide operators the confi dence of submitting accurate results to offset against carbon emission allowances.
