Auditing, Controlling & Sorting (ACS) Services


Waste is a subjective and inaccurate term as waste to one person is not waste to another. It can be quantified by size or weight, but there is a big difference between both approaches. Organic waste for instance is much heavier when it is wet, while plastic and glass bottles can have different weights but the same size. Furthermore, the definition of waste and what falls into waste categories also varies from country to country, making the complete picture even more complex. Because of the inconsistencies, extrapolation of data from one country to another or from one waste type to another is not possible. Therefore, and as waste identification is regularly used to determine and, if possible, optimize waste collection and treatment, precise and reliable data on the composition is in those cases of utmost importance. In this context, OWS offers services in determining the composition of waste with the precision and discipline of a laboratory.

Analyses on plastic, glass, metal, paper, organic waste, mixed waste,… have been performed several times. Also the technical analysis and evaluation of the waste treatment processes and installations is a part of the services of ACS.
