Bakgrunden till detta examensarbete är att Papyrusområdet i Mölndals Kvarnby står inför en omfattande ombyggnad. Området har till stora delar stått övergivet sedan tillverkningen upphördeår 2006. I området finns dock stora kulturvärden som bör tas tillvara på samt bevaras. Syftet med examensarbetet är att utreda hur byggnad 18 på området kan tas tillvara på och vilka nyaverksamheter som kan vara lämpliga för byggnaden i det nyplanerade området. I examensarbetet utförs 3 delstudier för att undersöka vilka verksamheter som lämpar sig bäst för byggnaden och för området.

The access to good sanitary facilities is an important factor that elevates the experienced living standard as it improves hygiene and reduces the transmission of deseases. The ratification of the millennium goals by 189 countries demonstrates that this is an important international issue. Together the countries have taken upon themselves that the proportion of the population that lacked access to sustainable safe drinking water and sanitary facilities in the year 2000 will have been reduced by half by the year 2015. In Peru, the construction of sewage pipe networks to transport the sewage out of the direct human environment is progressing. The safety and sustainability of these systems can be questioned, since in Peru the sewage seldom receive any treatment before being emitted to a recipient. This is taking place in Picota and sorrunding villages as well. In the last 25 years several systems implementing small-scale onsite treatment have been introduced throughout Latin America in an attempt to give more people access to sustainable and safe sanitary facilities, reducing water consumption and taking advantage of the agricultural values of the sewage fractions while protecting the environment from its negative impact. In this study three different sanitary systems and the effects of different population growths were compared.
