Abstract
The city of Lund updates the handling plan of garden waste with the desire to use it for biogas production. Garden waste works best as biogas substrate when it is separated in two fractions. Today, however, there are no sorting of the residents’ garden waste. The aim of the thesis is to explore how private households can sort out a fraction of garden waste that can be used to produce biogas.
Firstly, a literature study of how garden waste is suitable as substrate was completed and past experience collected. The part of the garden waste that is best suited for biogas production is the soft material that is not woody, like grass clippings, fallen fruit and flowers. In Sweden there is no experience of digesting garden waste. The identified... (More)

The part of the garden waste that is best suited for biogas production is the soft material that is not woody, like grass clippings, fallen fruit and flowers. In Sweden there is no experience of digesting garden waste. The identified European plants digest garden waste by dry fermentation.
Secondly, an interview study was carried out, in which Swedish municipalities and waste companies shared their experiences. It appeared that the sorting of garden waste is usually done at the recycling center in two main fractions: twigs and branches or grasses, leaves, fallen fruit, etc. Most respondents indicate that their customers are good at sorting garden waste. In some municipalities there are so-called gardening tips which bring the collection closer to the population and reduce transportation.
Two main conclusions can be drawn, it is possible to make biogas from garden waste and it is also possible to implement a system where residents sort garden waste into at least two fractions. (Less)
