Glasdeposits from waste to resource

The Kingdom of Crystal in Southern Sweden flourished during the 19th and first half of 20th century with many of the glassworks producing lead-containing art and household glass. Today 40 of approximately 100 glasswork sites are listed as very high risk and has to be excavated. The amount of glass and metals are not so easily determined but from investigations of 22 sites the estimated glass volume at the 40 sites is in the order of 100 000 m3, the amount of lead  6 200 tons and 800 tons of arsenic. The yearly leakage to the environment is estimated to 300 kg  lead and 90 kg arsenic. There is a resources of metals and glass in the Kingdom of glass, can we recover it?

In previous projects we have shown that it is possible to separate lead and glass in small scale. We have achieved a state-of-the art melt separation technique giving a glass phase with less than 0.1 weight% lead for well-defined samples. In our new project we will verify an industrial scale method to recycle lead glass waste from landfill sites and investigate how to best implement this in the ongoing remediation of the Kingdom of Crystal.

Combustible Construction and Demolition Combustible Waste in Sweden: What is in it and potential for improved source sorting

In order to achieve material circularity in more than 10 million tons of construction and demolition waste yearly generated in Sweden, it is crucial that the fractions that are nowadays incinerated go to recycling instead.

Among the main barriers identified, financial incentives are considered to be the main obstacle for diverting materials from the combustible waste stream to a more sustainable waste handling.
