Reduce emissionReducing emission is important in order to contribute to a sustainable development. The production efficiency and how well you are utilizing your raw materials affects your emissions.
In order to reduce your emission you need to know the current status and the sources of emission. Start by mapping todays’ situation: what is the size of your emissions to water, air, landfill and recovery? This can be detected by sampling.
Many companies measure their emissions to water through the analysis of COD (chemical oxygen demand) or BOD (Biological Oxygen Demand), and possibly nitrogen and phosphorus. It can be challenging to connect BOF or COD to shrinkage of raw materials, but if you know what goes down the drain and how much the relevant components contribute to BOD / COD, you can get good estimates of shrinkage to drain. I have identified shrinkage of 1.4 million $ / year for a company by mapping emissions. By gaining control of your emission, you can achieve significant savings.
I have also prepared an IPPC (Integrated Pollution Prevention and Control) report for a customer, where all emissions and waste were described and quantified. Part of the scope was to compare their processes to BAT (Best Available Technology) and do benchmarking. You can read more about this IPPC project.
Monitoring programIn Norway, emissions are regulated through the corporate discharge permit. The Norwegian Environment Agency requires that Norwegian companies document their emissions to soil, air and water to ensure that they are within the requirements of the permit.
In 2010 came a demand from The Norwegian Environment Agency to establish a monitoring program in order to achieve emission control. Lean Tech was hired by Allnex to create a Monitoring program for emission to air. The work included calculation of the various emission sources contribution to the total emission. The uncertainty related to the various emissions was also determined. The monitoring program focused on achieving the lowest uncertainty for the greatest emissions. When preparing a monitoring program it is important to consider the normal production conditions and the natural variation of the emission in order to achieve representative sampling. Seasonality needs to be taken into account, and measurement uncertainty for the analyses carried out must be determined.
