In Oslo, Norway, the Haraldrud sorting plant has adopted optic
bag sensor technology since 2009. The plant handles approximately
150,000 tonnes/year of food waste and is currently the
world’s largest optical sorting facility for separating food waste
from other household wastes (Envac, 2014). Experience from this
city suggests that the residents quickly accept this type of waste
sorting system. Other examples of optical sorting plants with two
fractions (i.e. food waste and other residual wastes) can be found
in cities such as Södertälje and Borås in Sweden, Øras and Mo i
Rana in Norway, and Jakobstad in Finland.
