Norwaste has been in Trondheim and conducted two extensive pick analyses for Trondheim Renholdsverk AS (TRV). The purpose of the analyses was to examine the composition of household waste, the proportion of residual waste that is sortable, and misplacements in the source-separated fractions. Part of the assignment was to examine the distribution between food waste and non-usable food waste. The first analysis was conducted in the fall of 2021, where approximately 6.3 tons of cardboard and paper, plastic, glass and metal, and residual waste were sorted into 53 fractions. At that time, Trondheim did not have source separation of food waste. After the analysis, TRV implemented a source separation system for food waste in selected areas. To measure the effect of the measure, a similar analysis of household waste was planned for February 2022. Despite there still being food waste in the residual waste, the results show a decrease from 45% to 33% of food waste in the residual waste after the introduction of the food waste collection solution. In addition to pick analyses of household waste, Norwaste has conducted analyses of municipal operational waste in Trondheim municipality. Here, waste from kindergartens, schools, and health and welfare houses was examined.   Previous Next
