Envac Optibag AB – Optical sorting hall

Envac Optibag AB is a technology company with a leading position when it comes to safeguarding the environment. With the whole world as its market, Envac Optibag has supplied over 25 plants in the field of waste management.

The Optibag concept is a smart sorting system which allows individuals to sort their waste at source according to their own needs, in different coloured bags. The waste bags can then be thrown into the same bin because they are later separated by colour in an optical plant at a central waste facility. Optibag takes up very little space and reduces waste collections. The organic waste from the green bag can be turned into biogas for public transport, cleaning vehicles and private cars.
