115 48 Tool for measuring food waste C.B. Letting, K. B. Rasmussen, M.S. Larsen, S.M. Fohlmann and S. Seitz- Rasmussen 2DTU Diplom, Technical University of Denmark WHAT IS THE PROBLEM? Every year Danish citizens tosses 63 kg edible food per person in the trash bin, this adds up to the equivalent amount of 16 billion Danish kroners. This is a problem due to resources, water and energy spent producing and transporting the food from field to consumer. This overproduction has a huge impact on the climate change. Food waste is not an unknown problem for the consumer and is synonymous with “a dirty habit”. There is a continuous growing will to reduce food waste by the end consumers as the problem becomes more and more obvious. WHAT ARE WE THE INSPIRED BY? Throughout the research we have conducted, we have come across several homepages and movements pointing to different ways of changing the culture of food waste. www.StopSpildafmad.dk is a NGO which is trying to change the behaviour trough debate, enlightenment and hands-on solutions. Our research has shown that there are a lot of tools for reducing food waste, though they are more lifestyle than hands on-tool. The waste of food is also happening very much at the retailers, and FDB, United Danish Cooperative Society, published a report of the consumers’ habits in regards to food, meals and waste. We have been inspired by the recommendations for how to lower the food waste generated in families. Also the members of our group have been looking into their own habits around food making and eating and what happens after this event. HOW DO WE SOLVE THIS PROBLEM? We propose a simple and energy neutral solution, which will give the consumer a better insight in how much biological waste they generate, and dispose on a weekly basis. Our tool will furthermore give a direct link between wasted food and CO2 emission generated. By giving a more accurate value of the weight of the waste generated, the consumers can get a first hand view of their waste and habits around shopping and food making. We will provide a simple way to monitor, and register, how much food is wasted, and give an estimate on how much money and CO2 could be saved, with a very small effort in changed habits. LCA Materials Production Use Diaposal In all CO2 2,45 kg CO2 0,183 kgCO2 0 kg CO2 -0,08 kg CO2 2,553 kg CO2 Energy 54,5 MJ 2,86 MJ 0 MJ -11,2 MJ 46,16 MJ Table 1: This LCA form shows the CO2 and energy costs in production, usage and disposal of our tool. The average consumer disposes 150kg CO2 pr. year. We propose that our solution will decrease this number by 15%, and will approximately save 22,5 kg CO2 pr. consumer pr. year. With these figures, the production of our tool will be CO2 neutral after just 40 days. After this, it will be providing a surplus of savings for at least 5 years that is the estimated minimum lifespan of our tool. WASTE & RECYCLING FREE STYLE CONCEPT BACHELOR LEVEL COURSE / PROJECT
