Wastes with caloric content-a potential alternative fuel for manufacture of portland cement clinker Nedelescu, E. Morer. Consrr. (Bucharesr), 1999, 29. (I), 6669. (In Romanian)
The results of chemical and energy investigations of the potential of wastes with caloric content, such as electrode waste and scrap tires as alternative fuels for manufacture of portland cement clinker. The characteristics of the wastes and the heavy metal emissions are provided. In addition, the feed points for these wastes in the burning line are described.

Willow growers in Sweden Rosenqvist, H. Biomms und Bioenergy. 2000, 18, (2), 137-145. The number of willow plantations on Swedish farmland increased considerably between 1991 and 1996. The main driving forces behind this development were: (1) The introduction in 1991 of a new agricultural policy in Sweden which, through deregulation, created lower grain prices and simultaneously introduced compensation for set-aside land as well as subsidies for willow plantations on surplus arable land; (2) higher taxes on fossil fuels; and (3) the existence of a biofuel market in Sweden based on forest fuels. This paper presents a statistical study of willow growers in southern and central-eastern Sweden. Data about willow growers and a stratified random sample of non-willow growers were acquired from the 1995 Farm Register compiled by Statistics Sweden. Willow growers are described according to geographical distribution, willow parcel sizes, farm sizes and farm types. Comparisons
