Our automated waste collection system sorts, collects, and reuses waste for purposes such as waste-to-energy and recycling, reducing pressure on landfills. We use advanced technology that has proven to be highly efficient and has the potential to significantly reduce our carbon footprint. This breakthrough could pave the way for a cleaner and more eco-friendly future in our cities. With automation in waste collection, resource circularity is a reality that we can experience in our daily lives.


  1. Sorting – the key to successful waste management By collecting multiple waste fractions, users can contribute to higher recycling rates and promote circular resource use in their municipality.
  2. User recycling engagement and awareness With the ReFlow app, users receive guidance on sorting recyclables, as well as feedback on their recycling performance and impact on the environment.
  3. Waste to energy, fuel and fertiliser By better sorting waste streams at source, Envac systems can help to generate energy from municipal waste.

Recent studies conducted by Envac’s partner, LocalLife, among a niche focus group have demonstrated that ReFlow can lead to:

reduction in waste generation
increase in plastic recycling


New Envac systems are being installed in Stockholm neighbourhoods to meet customer feedback. The ReFlow system will initially serve up to 600 apartments and expand to 6,000 apartments within eight years in the neighbourhood.

More than 50,000 additional daily users of Envac system in 2022 compared to previous reporting year.

With a sorting capacity of 150,000 tonnes annually, the installation sorts five household waste fractions in coloured waste bags: PMD, textile, kitchen, garden, and residual waste.

ReFlow solution free version with all new Envac installations and upgrades will be offered in the future.

Optical waste sorting optimised in Belgium

The region of Limburg, Belgium, now benefits from Envac’s optical sorting system, which has been operational since 2022.

This facility is responsible for accepting, storing, transporting, and sorting household waste bags with high efficiency and hygiene. The installation design prioritises maintainability, safety, standardisation, and availability. The use of state-of-the-art technology also ensures that the power consumption of the installation is minimised.

  • With a sorting capacity of 150,000 tonnes annually, the installation sorts five household waste fractions in coloured waste bags: plastic bottles, metal packaging and drink cartons, textile, kitchen, garden, and residual waste.
  • The facility’s approach to waste management follows the principles of source separation and multi-stream collection using a single waste truck, which significantly reduces the number of kilometres driven by waste trucks and CO² emissions.
  • Additionally, the sorting installation can sort two more fractions in the future.

Envac scoops top Korean Environmental Award

  • In November 2022, Envac was awarded the sustainable waste treatment prize for a system that weighs deposited food waste so that users pay for the waste collection based on the principle of “pay as you throw”.
  • The system is designed to raise resident awareness of how much food waste they produce and to encourage them to waste less.
