    Biowaste is composed of food and garden waste, which can easily be utilized for energy and nutrient recovery. A part of biowaste, however, still goes to landfilling, which cause harmful emissions and leaks to the environment. This pro gradu study was carried out as a part of JaloJäte- project in Etelä- Savo and Satakunta. The purpose of JaloJäte- project was to develop models for biowaste exploitation with corporate social responsibility. The aim of my study was to examine if there was any correlation between the amount of biowaste as dry matter and the revenues of the food companies. My study also gives information on which food sector produces most amounts of biowaste amount as dry matter proportional to the revenues as euros of the food company. The utilization of biowaste is also reported in different food sectors. The method was empirical and the study qualitative. I collected the information for the study by phone and by emails from food companies from the years 2007 to the year 2009. I got 102 interviews from food companies. The results indicate that when the revenues as euros of the food companies grew the biowaste amount as dry matter decreased. According to the study agriculture with fishing and food industry sectors produce more biowaste as dry matter per euro than food stores and restaurants. The biowaste utilization varied in different food chain sectors. The most popular biowaste utilization forms were composting, direct field use and feeding animals. Others more marginal biowaste utilization forms were burning and rotting. Unfortunately a part of biowaste still goes into landfilling. This cannot continue for long, because placing biowaste into landfills will be forbidden from start of the year 2016. Hopefully this will change puplic opinion so that biowaste will be considered more as a useful byproduct than as waste. More researche is needed on biowaste utilization, so more effective and economical recycling forms can be develop.
