Produktutveckling av nuvarande soptunnor för att använda mindre plastpåsar i de allmänna utrymmena i Stockholm (Swedish)
Abstract [sv]

Över de senaste åren har det uppenbarats en trend att minska spillet av plast för att förbättra världens miljö. Mer specifikt har det observerats att vid många tillfällen slängs avfall även fast soppåsen ej är helt full. Därför är idéen att ej använda vanliga soppåsar utan att istället justera storleken i enlighet med mängden avfall. Idéen finns redan idag, uppfunnen utav Paxxo AB, men det finns möjlighet att utveckla deras idé för att kunna använda deras produkter även ute i allmänheten. I synnerhet i tunnelbanestationer i Stockholm finns det potential. Syftet med detta examensarbete är att ta reda på om det är ett effektivt sätt att reducera miljöutsläpp medans det samtidigt kan vara kostnadseffektivt. Ett annat underliggande syfte är att ta reda på hur utvecklandet av konceptet kan ske. Slutsatsen är att det är effektivt att genomföra detta koncept, arbetet innehåller även ritningar och uträkningar vilka kan användas för att nå det slutliga målet.

Abstract [en]

It has been a trend over the years to reduce plastic usage in order to have a better environment. In this context it has been observed that most of the time the plastic bags for garbage bins are collected even if they are not completely filled with waste since the waste was contaminating the surrounding environment. In this matter the plastic bag with much bigger volume of capacity is being used for the small amount of the waste. The idea is to have adjustable plastic bags in volume. In case the amount of the waste is smaller than the bag, the size of the bag could have been reduced to the same size of the waste. In this matter, there would be a great deal of plastic saving.This idea has been already conducted by the PAXXO AB Company. Their product which is named Longopac is an extendable roll of bag in a circular shape that it could be used for waste disposal applications.It has been decided by the author to individually (without collaborating with PAXXO) to propose a complementary idea to the company’s product and afterwards contributing it to PAXXO AB. The idea is to propose a concept in order to be able to use Longopac in public areas; specifically the metro stations in the city of Stockholm. The purpose is to assess if this idea is an effective way to reduce environmental emissions while at the same time being cost effective. Another underlying purpose is to propose design concepts for implementing it.The conclusion is that this idea is efficient; the work also contains drawings and cost estimations that proving that this idea is doable while being cost effective.
