A device includes a compartment for separating the solids and liquids. The compartment includes a base that is concavely curved according to a cylindrical portion having a transverse axis and is formed of a sieve, an idler roller mounted transversely on an arm, a drive which actuates the arm, and resilient means for adjusting the pressure exerted by the rollers. Both the contact interface between the sieve and the roller and the rotational interface between the roller and the arm are made of a non-metal material on at least one of the two contacting surfaces that form each of the interfaces, such that, there is no metal-on-metal contact between surfaces moving relative to one another at the interfaces.

A liquid suspension of lignin-rich microparticles can be recovered from anaerobic digestion of ruminant animal manure. This has similar particle size distribution to that obtained from anaerobic digestion of steam pretreated lignocellulosic feedstocks. This demonstrates that similar lignin-rich microparticles can also be formed biologically, in the absence of thermal treatment that melts lignin. As a consequence, given a sufficiently complete digestion, lignin-rich microparticles will be formed during anaerobic digestion of ruminant manure and of lignocellulosic feedstocks that have never been steam pretreated to temperatures above the lignin melting point. Methods for recovering and valorizing this lignin are disclosed.

The present disclosure discloses a moss-covered green manure and an application method in assisting ecological remediation. The moss-covered green manure includes the following parts by weight of raw materials: 30-38 parts of plant fibers, 30-35 parts of moss, 5-8 parts of paclobutrazol, 5-7 parts of a growth regulator, 50-62 parts of humus soil and/or an oil cake, and 35-47 parts of electrolytic water. According to the moss-covered green manure and the application method in assisting ecological remediation provided by the present disclosure, bare soil is covered by arranging cooperative moss-covered green manure in a non-planting area of a remediation plant to ensure the beauty of the appearance. Meanwhile, the soil can also be improved by further utilizing the advantages of preserving moisture and fertility, improving the nitrogen fixing capacity of the soil and not competing with plants for fertilizer of the moss-covered green manure.
