Analysis of Picked up Fraction Changes on the Process of Manual Waste Sorting

The problem of proper organization of waste management systems is becoming more and more significant these days. In Poland, regulations requiring municipalities to achieve by 2020, 50% recovery of weight fractions such as paper, metal, plastic and glass are the main factor contributing to the need to undertake new activities in the field of waste management. Waste processing takes place in complex technical systems. Modern waste processing systems are characterized by low efficiency. Currently, it is estimated that the efficiency of installations dealing with the sorting of waste does not exceed 35%. In 2015, the authors of the article carried out waste morphology in the city of Wroclaw (only selectively collected waste). On its basis, the authors established that fractions suitable for re-use accounted for 77% of the total weight of waste sent to processing plants. Despite the significant development of systems for automatic identification and sorting of waste in recent years, systems using mainly human labour are still very common. The main goal of this article is to analyse the impact of changes in the type of waste picked up on consecutive workstations on the value of indicators used to evaluate the process of manual waste sorting.
