In Austria the separate collection and treatment of municipal biowaste was introduced about 1989, and is now ordered by law since January 1995. From a population of about 7,8 Million, living in 3,1 million households, the expected total quantity of biowaste, coming from municipalities, parks and gardens, and the commercial sector is about 2 million tons per year. This quantity should be collected by the year 2000. At this time about 42% of the organic waste will be managed decentralised and composted by private people and farmers. About 58% of the biowaste is treated in composting plants with a capacity of more than 50t/a up to 100.000t/a. On the one hand in Austria a lot of new biowaste treatment plants have to be built, on the other hand existing co-composting plants have to be reconstructed and enlarged to convert biowaste with aerobic or anaerobic technologies into high a quality compost product.
