This waste is produced from Agricultural activities in the South East. The main types are;
- Spent Mushroom Compost - 13,260 tonnes of dry solid spent mushroom compost (SMC) is produced in the region each year.
- Animal Slurry – 421,920 tonnes of dry solid animal slurry was produced in the south east region in 2003. Slurry is generated when animals are housed indoors and slurry is stored for disposal. Manures generated from animals while outdoors is naturally deposited on agricultural land are not included in the total figure. Cattle are housed on a seasonal basis. Sheep ewes are only housed during the lambing season. Pigs and poultry are normally housed indoors all year round. Slurry management from horses is assumed to be from housing thoroughbred horses indoors at night for 26 weeks of the year.
- Straw – It is estimated that 700,000 tonnes of straw waste produced from cereal crops in the South-East per annum. Straw is used for animal bedding, the manufacturing of mushroom compost and is ploughed back into the land.
