Abstract

According to Regulation of the Minister of Environment of December 29, 2016, on the detailed method of selective collection of selected waste fractions, selective collection of biowaste is mandatory. Biowaste stream can consist of both kitchen waste and biodegradable waste from gardens and parks. Kitchen waste and ?green waste? can be selected separately or collectively. Properties of kitchen waste and green waste can differ significantly. Considering fermentation as the main treatment method for these types of waste, the biggest difference between green and kitchen waste are the organic matter content, and the type of polymers forming it. Because of that initial study of biowaste, the collection system's influence on methane production was performed. For this purpose, three types of biowaste were investigated. Separately collected kitchen bio waste, green biowaste and its mixture. This approach will allow analyzing both separate and joint collection system. The result indicated that kitchen waste exhibited the highest methane yield reaching 435 m3·kg-1 (total solids) which was more than 6 times higher compared to the result obtained for green waste. Obtained data may help to decide the best approach for treating biowaste collected in separate systems.
