Abstract: The invention relates to an arrangement for charging granular or pulp-like material to a container of relatively large cross-sectional area with the aid of a conveyor, in a manner to maintain a constant, smooth level of material in the container. The arrangement includes a carriage which can be driven at least partially over the cross-sectional area of the container on a level above the level of material present therein. The carriage has mounted therein at least one pair of juxtaposed and mutually spaced feed means, arranged to impart to the material a component of movement in the same direction and each of the screw means being arranged to impart to the material a component of movement directed towards the interspace between the feed means.

Abstract: The invention relates to an arrangement for preparing compostible material for introduction into a composting plant, the material containing sludge and carbon-bearing material.

Abstract: The invention relates to a method for producing a product from which compost can be suitably produced and which contains sludge obtained from a sewage purification process, in which method the sludge is mixed in a fluid state with a finely-divided carbon-carrier selected from the group sawdust, peat and bark, and with polyelectrolyte, and is then mechanically dewatered to a dry substance content of at least about 28 percent by weight.
