Composted green material and its use in growing media
The initial focus of this research was to establish various trends in green waste production for example variation in source and treatment of green waste. A comprehensive overview of the current green waste cycle was undertaken via a questionnaire titled 'Management of Green Waste'. From the producers of composted green material identified in the survey, fifteen sources agreed to participate within a study reviewing best practise leading to the production of material suitable for inclusion in growing media. Due to increasing external pressures, the use of composted green waste as a potential alternative or diluent in growing media is being considered. If composted green material was to be used in the retail and professional markets, storage is of paramount importance. However very little information is available on the effects of storage on composted green material. Therefore the next step in this research was to conduct growth/storage trials using varying percentages of composted green material mixed with peat. The mixtures used in the trial were split, half of the material was stored in a 10˚C constant temperature room, and the other half was stored in green house conditions.
