Compositional Analysis Services - Brochure

Compositional analysis provides a detailed breakdown of the materials within any waste or product stream.Within the waste and recycling sector process streams are often complicated mixtures of materials. Understanding the composition is vital for designing new separation facilities such as MRFs or MBTs, assessing local authority collection services or understanding consumer behaviour with regards to waste disposal. Analysis is only worthwhile if the results are statistically representative. This means the method of sample collection and the correct sample size are specific to each material type and the average weight of individual items in the waste stream.Axion has developed a range of techniques to ensure samples are representative and that the results are statistically meaningful. We apply the correct methods to each task and have perfected a portable software-based tool which allows any sampling or measurement task to be checked for accuracy and reliability “right on the job”. Sorting can be carried out either at an external site where we will plan and manage the trial, supplying all necessary equipment, or samples can be transported to our Salford based plant for analysis. Axion have carried out compositional analysis for both private and public organisations. Typical material streams previous analysed include:• Household dry mixed recyclables• Residual black bin bag waste• Commercial and industrial waste• Construction and demolition • Waste Electronic and Electrical Equipment (WEEE)• Food waste (Back of store) •• MBT and MRF products such as:HDPE/PET bottlesPots tubs and traysMetalsRDF and SRF News and pamphlets, card and mixed paperResiduals CA-11/13-1.0 © Axion Recycling Limited, 20130.005.0010.0015.0020.0025.001 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23Percentage Point Change Sample number Percentage Point Change in Composition Graph illustrates that variability reduces as sample size increases. © Axion Recycling Limited, 2011Compositional analysisContact us:Please call Axion Consulting for further information:+44 (0) 161 426 7731info@axionconsulting.co.ukAxion Consulting Ltd., Unit 2, Tudor House, Bramhall, Cheshire SK7 2DGwww.axionconsulting.co.ukWho is Axion?Axion Consulting develops and optimises processing and collection methods to recover value from waste resources for a wide range of clients within the recycling and process industries. Axion specifies, designs and commissions innovative process plants for companies in the recycling sector, advising on plant design and equipment selection. We also help with process optimisation and staff training once plants are operating.We have a team of enthusiastic process engineers and project managers that can draw on extensive experience in the recycling and process sectors with special expertise in mixed waste and biofuels.What makes us different?We have designed, built and now manage our own advanced technological resource recovery plants. Our consulting is based on a combination of practical experience and scientific knowledge.Our experience Over the past ten years Axion Consulting’s Process Engineers have seen numerous examples of sampling and analysis methods being employed to provide critical process control data which is then used by site managers to make important commercial decisions.On many occasions the design of the sampling method, the frequency and size of the samples being taken are inadequate for the required level of confidence in the results. Often the ‘sampling method’ is chosen by site operating staff based upon a loose guess about what feels right. The selected material sample is then transferred to an analytical laboratory where further sub-samples are taken at random and complex preparations carried out to allow an expensive instrument to be applied and yield a ‘key number’ as the end-result. Management later reports that the test results are ‘varying wildly’ and ‘cannot be relied upon’.
