This thesis has been done at the powder department (GH) at AB Sandvik Coromant in Gimo. With a rheometer measurements has been made on raw materials and powder blends. The focus of this report has been to find correlations between raw material powders and press data, comparisons have also been made between raw materials and powder blends. The rheometer can show information of how a powder act in flow conditions, together with air and with pressure. Analyses has been done comparing the rheometer data with press parameters (for example: rejected orders, weight variations and the compaction pressure) with the goal to find correlations between the powders flow properties and the powders compaction in production. The measurements and analyses have been showing that the powder flow properties depends on the powders composition and that properties like flow rate, aeration and permeability varies between powder blends and batches of the same powder sort. It seems to exist a correlation between the pressure force and the flow rate of a raw material. This flow rate seems to belong together with the flow rate of the powder blend. No correlations were found between the rheometer measurements and press rejections, weight variations and hall flow values. The statistical analyses that has been used in this report consist of a few number of measured values and for the analyses to be statistic correct it is necessary to have a larger sample in the analyses.

The Baltic Sea is one of the world’s most polluted seas. Increased discharge of nutrients due to greater populations of people, together with a slow water exchange, creates great stress on the sea. Too much nutrients leads to increased growth of algae and causes problem in the ecosystem. Even if we reduce nutrient discharge the problem still exist in the ocean. When algae dies and sinks, more nutritional substances is produced called "internal eutrophication". This phenomenon will grow in the future due to a warmer climate and the problem is spreading towards the coastal zone, which is an important site for fish recreation. By removing the abundance of algae, the nutritional and toxic substances are reduced and the algae biomass can be a future resource for biofuel production.

Klimatförändringar är ett faktum, och den globala livsmedelsproduktionen står för 25 – 30 % av de totala utsläppen. För att minska utsläppen krävs det stora förändringar i samhället. För den enskilda individen kan ett minskat intag av animaliska livsmedelsprodukter göra stor skillnad för miljö och klimat. För att lyckas med detta krävs det en attitydförändring och ökad kunskap bland konsumenter i samhället. Syftet med studien är att undersöka konsumenters attityder och intresse för en svenskodlad hampadryck. Relevant litteratur och teori användes för att få en ökad förståelse av människors matval och preferenser. Fokusgrupper användes som metod för att öka förståelsen för konsumenters attityder kring olika faktorer av hampadrycken. Urvalet baserades på heterogena grupper med olika kön, ålder och utbildning för att få en bredare diskussion. Studien resulterade i fyra olika teman som fokuserar kring hampadrycken. Allt handlar om smaken, Intresse och medvetenhet för svenskt, Marknadens mervärde och Attraktivt med tydligt innehåll. Dessa fyra olika teman hjälper till att få en helhetsbild av konsumenters kunskap och medvetenhet, och även vad som efterfrågas på marknaden, ur ett konsumentperspektiv. Människan är en komplex varelse och det finns många aspekter att ta hänsyn till vid förändringar,inte minst maten och måltiden. Sammanfattningsvis kan man se ett stort intresse och medvetenhet kring hållbara matval bland konsumenter, och en stark vilja att förändra sitt ätande för en bättre miljö. / The climate change is a fact, and the global food production is responsible for 25 – 30 % of the greenhouse gases. To reduce the emissions major changes are needed in the society. For the individuals, a reduced intake of food products made of animals can make a big difference for the environment. To succeed in this matter, a change of attitude and increased knowledge among consumers in the society is required. The purpose of the study is to investigate consumers attitudes and interest in a beverage made of Swedish-grown hemp. Relevant literature and theory were used to gain an increased understanding of people’s food choices and preferences. Focus groups were used as method to interpret consumer’s attitudes about various factors of the hemp beverage. The selection of participants was based on heterogeneous groups with different genders, age and education and the purpose of this was to have a broader discussion among the participants. The study resulted in four different themes with focus around the hemp beverage. It is about the taste, Interest and awareness of Swedish products, The markets added value and Attractive with a clear content. These four different themes are helpful to get an overall picture of consumers knowledge and awareness, but also what is in demand in the market, from a consumer’s perspective. Humankind is a complex being and there is much to consider when change occurs, especially when it is about food and meal. In summary, there is a great interest and awareness for sustainable food choices among consumers, and a strong desire to change their eating habits for a better environment.
