Study on the economic viability and environmental impact of different solutions for shielding gas (English)
Abstract [en]

Most people agree that the Earth's climate is changing and that it's anthropogenic actions that are the cause of it. The year 2015 was a historic milestone for the Earth's future climate. A climate agreement was signed by several heads of government worldwide. The agreement will take place and enter into force 2020, with a goal that the earth's temperature must not rise more than 2 degrees. In order to achieve this goal all countries, states, communities, entrepreneurs and companies begin to work together to reduce emissions.

The coffee rostary Löfbergs aims to reduce their carbon footprint by 40 % to 2020. To achieve the goal, they are working with sustainable actions to reduce the climate impact of all processes the coffee undergoes before it is a drinkable cup of coffee. The enviromental work done in the production is performed constantly, often by both large and small energy efficiency of technical and mechanical processes. The purpose of this study is to investigate whether Löfbergs shielding gas requirement can be improved by comparison of the current technical solution to other alternative solutions. The goal of this study is to find solutions to improve Löfbergs energy, climate impact and cost, through technological improvements of the shielding gas requirement.

Comparisons and calculations in this report is mainly done by studying each process lifecycle, to analyse and determine the climate impact of the product flows for the studied solutions to the shielding gas requirements causes. According to the results obtained in the present report, which covered five different solutions to shielding gas requirement, financial savings can be made by around 900 000 Swedish kronor per year and the environmental impact is improved up to 71 %. Both better and worse solutions to climate change and economic cost is presented in the report to guide Löfbergs in the development of a more cost- and energy-efficient and climate-smart business.
