A method and system reprocess soiled animal bedding material commingled with animal manure. In one aspect the soiled animal bedding material is separated in a shaker to send at least a preponderance of the manure to a holding tank. In another aspect the bedding is cleaned, rinsed and color is restored. The bedding material is subsequently dried and a bedding product, fertilizer product, and/or compacted product is formed. Alternatively, the bedding material is dried (without a compacting step) to form a product. In yet another aspect, the steps of separation, cleaning, rinsing and/or color restoration may be omitted.

A compound of formula (I): ##STR00001## wherein p is at least 1, n is at least 1 and less than or equal to p; Ar is a polycyclic aromatic moiety, R.sup.1 is hydrogen or an optionally substituted hydrocarbyl group and each of R.sup.2, R.sup.3 and R.sup.4 is independently an optionally substituted hydrocarbyl group, provided that at least one of R.sup.2, R.sup.3 and R.sup.4 has at least 6 carbon atoms.

A fire starter device with a cloth or paper substrate, such as a herringbone cloth material, which is coated in a micro crystalline wax. Paraffin wax may also be added to the mixture in a small amount. The device is cut into strips which can be rolled or otherwise positioned to create a fire starter. The ends of the substrate may be left uncoated to promote lighting the ends with a fire source. An auto-starter element can be built into the fire starter near one of the ends. The substrate may be died or printed with a logo or other elements. The wax may be scented.

A fuel additive for fuel formulations comprising calcium sulfonates in an amount effective to limit or eliminate valve seat recession in engines utilizing such fuel formulations. The fuel additive may also include a detergent, particularly in an amount to enhance the VSR limiting effect of the calcium sulfonates. Also included are fuel formulations containing calcium sulfonates in a concentration effective to limit vale seat recession in engines utilizing the fuel formulations. Methods for treating VSR in piston engines are also provided.

A method for producing an odor-free HTC coal, at least comprising the following steps: a) providing a biomass; b) performing a hydrothermal carbonization in order to produce a carbon sludge, the carbon sludge comprising HTC coal and HTC process water; c) separating HTC coal and HTC process water by a mechanical dewatering process; d) heating the HTC coal to a temperature of at least 150 degrees Celsius in order to remove highly volatile carbon compounds.
