Re-Load lastpall : En jämförelse mellan Re-Load och alternativ lastpall

Engström, Per January 2011 (has links)
Syftet med denna undersökning har varit att underlätta för företaget Re-Load att presentera sin lastpall som produkt för potentiella kunder. Syftet har också varit att stötta Re-Load till att bli licenserad EUR-pall samt att successivt ersätta befintliga lastpallar och långsiktigt exekvera företagets affärsplan. Målet har varit att undersöka produkten avseende lönsamhet, miljöinverkan och hur den påverkade arbetsmiljön. Under-sökningen har genomförts med ett befintligt flöde där produkten använts och utifrån detta kunde en flödesstudie samt en komparativ produktstudie utföras med en alternativ lastpall. Med data hämtat ur detta flöde utfördes en investeringskalkylering, miljöberäkningar, subjektiva intervjuer samt dokumentation. Kalkyleringar och beräk-ningar har redovisats grafiskt för att erhålla ett presentabelt och över-skådligt resultat. Undersökningen visar att Re-Load lastpall har en dyrare grundinvestering men är mer lönsam i längden. Efter 15 måna-der har Re-Load lastpall och den alternativa lastpallen uppnår samma kostnad. Vidare visar undersökningen att pallen släpper ut mindre koldioxid än den alternativa lastpallen i det givna fallet. Resultatet visar också att pallen är mer hållbar än alternativa lastpallar, framförallt gällande tyngre transporter. Slutsatsen är att Re-Load lastpall är en lönsam investering i längden för detta specifika fall, men att resultaten inte bör generaliseras. Slutsatsen visar vidare att pallen har en positiv inverkan på miljön i jämförelse med denna alternativa pall. Detta är knutet till att Re-Load lastpall har en lägre vikt än den alternativa. Jämförelse av pallarna i arbetsmiljön är problematiskt och analyserna visar att Re-Load lastpall saknar utbredning för att kunna göra en betydande inverkan på arbetsmiljön. / The purpose with the investigation has been to support the company Re-Load represent their pallet as a product to potential clients. The purpose has also been to support Re-Load in getting their pallet licensed as a EUR-pallet, gradually replacing existing pallets and over time execute their business plan. The goal has been to study the product regarding profitability, environmental effects and impact on the work environment. The research has been carried out with an existing flow where to product has been used thus allowing a comparative product study with an alternative pallet. Investment calculation, environmental calculating, subjective interviews and documentation were performed with data from the flow. Calculations have been shown graphically to receive a presentable and foreseeable result. The research shows that the Re-Load pallet has a higher investment cost but is more profitable in the long run. After 15 months the Re-Load pallet and the alternative pallet reaches the same cost. Further on the research shows that the pallet discharges less carbon dioxide than the alternative pallet in the specific case. The result also shows that the pallet is more durable than alterna-tive pallets, specifically regarding heavy transports. The conclusion is that the Re-Load pallet is an profitable investment in the long run for this specific case, but the results should not be generalized. The conclu-sion further show that the pallet has a positive impact on the environ-ment in comparison to this alternative pallet. This is related to the Re-Load pallet being lighter than the alternative. Comparison of the pallets in the work environment is problematic and the analysis shows that the Re-Load pallet lacks expansion to make a significant impact on the work environment.

End of life scenarios for the Re-load pallets-how different waste scenarios impacts the life cycle environmental impact comparison with other pallet type

Ali, Azhar January 2011 (has links)
Increasing consumption and transportation gears the use of transport utilities which cause environmental effects over the globe. Environmental performance of three different types of pallets such as Re-load, plastic and corrugated fibreboard pallets are evaluated in this project. LCA tool is used to assess and compare their environmental performance in all phase of their life cycle but more focusing on end of life phase.   This study gives more emphasis to waste treatment options such as incineration, landfilling and recycling. Three different end of life scenarios have been used in this study such as 100% incineration, 100% landfilling and 100% recycling.   This study includes results of all the phases of all three types of pallets which are analysed in this report. More detailed results could be seen in excel sheets. Results of impact analysis tells that landfilling contributes to 14793 Kg CO2 of global warming potential in case of corrugated pallets. Incineration contributes to 12148.6 Kg CO2 of global warming potential. Recycling contributes to 7136 Kg CO2 of global warming. Re-load pallets show the major contribution of global warming is from landfilling approx 813.2 Kg CO2 of global warming potential. Recycling and incineration contribute to 438 Kg CO2 and 726.7 Kg CO2 of global warming potential respectively. In plastic case incineration contributes the most to global warming approximate 1183.8 Kg CO2 of global warming potential. Landfilling and recycling contribute almost the same approximate 932.6 Kg CO2 of global warming potential and 924.5 Kg CO2 of global warming potential respectively. Acidification impact show corrugated pallets cause high emissions when they are treat with landfilling and give negative values of incineration. In Eutriphication impact corrugated pallets are considered better in a sence they are inbetween 150 and 100 kg of PO-4. Re-load pallets give the least values when they are applied to different end of life scenarios.   According to the results recycling could be replace other waste treatment options because of less impact through out the end of life. Secondly, Reload pallets represent a environmental friendly product which can be improved more after this study. Lack of LCI data is the major problem in this study because it is not easily accessible and it is very time consuming part of this study. Results might be different if more data is available.   This study can be helpful for further study, for instance more replaceable scenarios will show different results for all three types of pallets. Moreover, it helps to compare more pallet types which are already in the market or propose to come in the market.
