Envac AB is one of the leading environmental technology companies in Sweden and the global leader in the vacuum waste collection industry. Envac invented the vacuum waste system.
The first vacuum system was installed in 1961, and today the systems are found all over the world - in residential areas, business premises, town centres, industrial kitchens, hospitals and airports.
The system is a part of the city infrastructure, just like electricity, sewage, water supply etc. The technology is, in all meanings of the word, a sustainable solution.
Envac has 35 offices in 20 countries in Europe, North and South America, the Middle East, Asia and Australia. The Envac group is organized in four business regions: North Europe, South Europe and the Americas, Middle East and India, Asia Pacific and Australia. In addition, Envac AB owns Envac Optibag AB (100%).

Number of employees: approximately 19,000. President & CEO of Envac AB is Mr Christer Öjdemark. Chairman of the Board of Envac AB is Mr Martin Svalstedt (CEO, Stena Adactum AB).
- Traditional, manual waste collections bring several negative consequences to the city and it's inhabitants, businesses and environment, such as:
- storage of waste in the public realm
- overfilled bins and containers
- impairment of accessibility
- problems with litter, noise and odours
- unacceptable working conditions for waste collectors
- and a less attractive city/neighbourhood.
Our mission is to contribute to a better urban environment by offering rational and sustainable waste collection systems and services, reducing and eliminating the negative consequences of traditional waste handling. Our customers are municipalities and developers with high requirements for rational and sustainable waste handling.
Underground waste collection systems will become a utility and part of the cities’ infrastructure. Envac should be recognised as the first choice and the global market leader.
Our goal is to offer our customers the most sustainable waste collection system on the global market. By most sustainable we mean:
- A solution with the lowest life-cycle cost
- A solution that has a positive impact on the environment in which it operates
- A solution that is safe, easy to use and increases recycling participation levels
We will achieve this by:
- Customising each installation to deliver the best solution for the project
- Continually developing and improving our systems and components to reduce their environmental impact and energy consumption
- Operating and maintaining our customers’ systems in order to reduce CO2 emissions, noise levels and odours
Our employees are committed to reducing their environmental impact by:
- Only using environmentally friendly company cars whenever available
- Reducing travelling to a minimum and by using technology such as video conferencing wherever possible
- Recycling all waste paper and electronic devices
- Respecting and obeying environmental laws and rules wherever they are in the world
We aim to be viewed as a proficient and reliable partner in automated waste collection. We will make every endeavour to improve sustainability levels in the development, design and utilisation of our systems. When it comes to technology, proficiency, know-how, quality and support, we want to be recognised as the global leader.

From dust to waste
It’s not quite clear who popped the question that was to be so decisive for the waste handling system of the future. But it is quite clear who were the four people around the table in Sollefteå Hospital on that momentous occasion at the end of the 1950s. There was engineer Torsten Karefelt, responsible for the technical work at the hospital, Olle Genberg, chief architect, Sten Olsson, consultant for heating and plumbing systems, and Olof H. Hallström, proprietor and managing director of Centralsug AB.
They had decided to meet at Sollefteå Hospital to discuss a new central dust vacuum system when the discussion suddenly took another turn. “If we can vacuum the dust from every corner of the hospital in one single system, why can’t we do the same thing with the waste?” The idea had not occurred to anyone before and no-one knew whether it was even feasible at all. But Olof H Hallström rose to the challenge.
Technical obstacles - a challenge
As a true believer in the power of technology, no technical problem was too difficult to solve for Hallström. A couple of years previously, with the aid of an inheritance from the sale of his family farm, he had purchased Ingvar Gustafsson AB, a company that later changed its name to Centralsug AB. It specialised in the construction and installation of central dust vacuum systems. With this experience behind him, Olof Hallström returned to Stockholm to work out an answer to a question that for many people still appears utopian today. Hallström kept his word and returned a couple of weeks later with a proposal for a vacuum waste-handling system for the hospital. The rest is history.
The first vacuum system ever
In 1961, Centralsug AB installed the first vacuum waste system in the world at Sollefteå Hospital. The system is still in operation today with many original parts from the early 1960s.
The first vacuum system in a residential area
But it was dust vacuum systems that kept business going for Centralsug in the following years. Despite many attempts to convince others of this waste technology, it nevertheless took until 1965, four years after the first installation, before Fastighets AB Förvaltaren, a municipality-owned housing company in Sundbyberg, decided to give it a try. So the first vacuum system for household waste in the world was installed in the completely new residential district of Ör-Hallonbergen. This system is also still in operation today.
Many years later Centralsug changed its name to Envac. But that is a different story.
