Knitting always begins with a line. As the needles and hands work together, performing the same action over and over again, the line quickly becomes a collection of lines, crossing, looping and locking. The looping and locking generates a surface, and the surface becomes a form. Knitting generates form. Knitting is commonly categorized as a craft, associated with quick hands, idle time, and everyday objects that clothe us, and as a result, the technique is often overlooked and rarely pursued beyond its’ culturally constructed boundaries. What if knitting constructed new forms that transcended the ordinary and the expected, and challenged tradition? What if those forms spoke to shape, space, and light? The following collection of lines documents research and material explorations in an attempt to reinvent and redefine the boundaries and application of a traditional arts and crafts technique.

Rönnskärsverken in Skelleftehamn is a smeltery owned by Boliden. Rönnskär receives raw materials from Boliden´s mines and electronic materials. The metals that are mined at Rönnskär are mainly copper, lead and zinc, as well the precious metals silver and gold, where copper is the largest volume of the metal production. Today Rönnskär meet the heat demand with waste heat from Rönnskär´s processes in its internal heating network and Skelleftehamn and Ursviken. During the colder days or accidents, Rönnskär´s energy central fires oil to maintain the steam demand for condensation of steam to the district heating network. Oil fired steam production is something that Rönnskärsverket wants to reduce.    This Report is a pre study that will present a future potential solution to utilize slutabs-heat for SO2 (l) production, thereby release intermediate circuit heat to the district heating network. In the pre study pipes, pumps, heat exchangers were dimensioned, and estimated installations cost was calculated. During the pre-study, drawings for installation of the pipelines was designed.    The pre study showed that is was possible to install pipelines and heat exchangers to make use of the slutabs-heat for SO2 (l) production, thereby release the intermediate circuit heat to the district heating network. The pre study also showed that the oil consumption in the oil-fired steam boilers would be reduced by 660 m3 during the estimate period and the payback time on the investment cost is 4 years.
