The invention relates to a novel, highly efficient tobacco smoke filter provided with mechanically (fibrous) and/or adsorptively filtering materials as well as chemosorptively filtering components, which comprises a synergistic composition containing at least one of a compound having a high nucleophilic additivity, capable of chemically reacting and stable adduct forming with excited and ground-level aldehydes not filtered out by the mechanically and/or adsorptively filtering materials; and at least one of a compound containing ##STR1## enediol structural moieties, wherein the enediol type compound or its combination suitably amount to at least 50% by weight of the other chemosorptive components and 40 to 300% by weight of the adsorptively filtering materials.

Highly efficient tobacco smoke filter

A process for producing cigarette filters comprising a compound containing L-ascorbic acid and having the compound added to an adsorptional filter material in a quantity of 5-200% of the amount of said adsorptional filter.

The invention relates to a new method for increasing the biological value of manures, dung-waters, organic wastes and/or soils rich in lysine. According to the invention manure, dung-water, an organic waste and/or soil rich in lysine, either of natural composition or supplemented with lysine, a lysine source and/or one or more agricultural chemical(s), is treated with at least 0.01 mole of formaldehyde or an equivalent amount of a formaldehyde source, calculated for one mole of free or bound lysine present. The treatment according to the invention results in a significant increase of plant growth and crop yield.

Method for increasing the biological value of manures, dung-waters,

A compounded plastic system containing 3 to 90% by weight of a crystalline polyolefine, 0.4 to 80% by weight of a non-crystalline polyolefine, 25 to 90% by weight of a pigment and/or filling agent, 0.5 to 10% by weight of surfactants, and optionally other polymers, wherein the system contains two surfactants of different HLB-values, the one surfactant having a HLB-value lower than 9 and the other surfactant having a HLB-value higher than 9, both surfactants being heat-resistant up to at least 160.degree. C. The compounded plastic system according to the invention retains the properties of the starting system even when admixed with widely varying amounts of filling agents, and even more, in certain respects it possesses improved characteristics.
