This report analyzes disposable packaging and returnable packaging with the methods life cycle analysis and life cycle costs analysis. These two different packaging are analyzed through the company Clas Ohlson’s packaging-flow. To get a picture of how the flow works, a visit at the company and email contact have been done with Clas Ohlson to get relevant information

Today Clas Ohlson has a big flow of articles to the stores without larger variations in the demand, with the exception of autumn, which is when customers start shopping for Christmas. Clas Ohlson’s articles are placed on a pallet and are wrapped into plastic-film for protection and to make sure that nothing will be stolen. In this report Plastic-film is compared to the company Nycopac AB’s product Nyco Sleeve. In Sweden Posten takes care of Clas Ohlson’s transports and is the company’s third party-logistics provider.

Nyco Sleeve is a type of pallet box, which is placed on a pallet with the possibility to place three units upon each other. The pallet box is possible to fold, which makes it doable to place pallet boxes upon each other in reverse transportation.

Our Life cycle costs analysis shows that Nyco Sleeve is profitable compared to continue using plastic-film as secondary packaging. Nyco Sleeve demands a larger investment, almost seven times larger than the price for plastic-film but the expenses will be recovered relatively fast because of decreasing transportation costs. Posten’s pricing depends on each pallet place that is used which means that Nyco Sleeve’s higher weight does not affect the price. The total costs decreases because Nyco Sleeve increases the fill ratio on each pallet place, which results that less pallet places need to be used in the transport. If Nyco Sleeve is used the total pallet places decrease from about 116 000 to about 93 000 pallets considering 2012s flow. Due to decreasing costs each year, the pay-off-method shows that the investment reaches break even in about 0.7 years

The life cycle analysis that examines the environmental impact of the packaging shows the same trend as the life cycle cost analysis, it is the transport that has the decisive influence on the environment. Important to note is that the transportations from Clas Ohlson’s warehouse to stores and the reverse transports stand for the largest carbon dioxide emissions and not the transportations from production or to waste disposal. The production phase’s emission is also important especially for Nyco Sleeve, which causes large amounts of emission compared to the plastic film. Decreasing transportations and that it is possible to reuse Nyco Sleeve even out the differences between the two packaging types when it comes to emission in production. The life cycle analysis’ scenario analysis shows that Nyco Sleeve environmental impact reaches break even after about two years compared to break even for the economic costs in 0.7 years. If only one loop is investigated the calculations show that Nyco Sleeve has larger environmental impact then plastic film but over time and when several loops are considered Nyco Sleeves carbon dioxide emission is economized.
