Collection and processing of organic residual waste

This indicator shows the amount of selectively collected organic waste streams used as input for composting or co-fermentation.

3.6 Mt

3.6 million tonnes input for biological processing

  • Organic-biological waste constitutes the largest fraction at 47%.
  • GFT and green composting are significantly lower in 2022.

What do we see?

In 2022, 3,566,548 tonnes of organic waste was collected separately. Throughout the years, we see a clear increase until 2020 that is mainly due to the larger fractions of organic biological waste and manure. The latter fraction in particular was a lot lower in 2021 and 2022 and this largely explains the lower overall figures in these years. In 2022, we also see a lower volume of VGF and green composting compared to 2021, with decreases of 12% and 16% respectively. The figure for green composting is the lowest in seven years. Green waste generation and processing are not easy to interpret or predict; weather conditions definitely play a role.



What’s the aim?

Besides preventively reducing food losses, the circular economy aims to valorise organic residual streams as much as possible. Examples include turning these residual flows into compost or using them as biofuels. Putting these streams to good use avoids the use of other raw materials. The aim is to get organic residual streams as high as possible on the value retention cascade. Their selective collection is crucial to enable high-quality processing.

What does this indicator measure?

This indicator shows the amount of collected organic residue streams used as input for composting or co-fermentation. The data for this indicator comes from Vlaco’s annual report.
