An object is to provide a Th1-increasing agent that can reduce constraints on storage conditions and feeding form and sufficiently increase Th1 at lower doses. A Th1-increasing agent containing a cellulose derivative as an active ingredient, the cellulose derivative having a degree of butyryl substitution of 0.3 or greater and 2.6 or less, and a total degree of substitution of 0.5 or greater and 2.8 or less.

The present disclosure provides a process for the synthesis of bio-based formaldehyde-free wood adhesive with lignin and cellulose derived bio-oil which can be generated from the fractionation/liquefaction of lignocellulose biomass such as agricultural and forestry wastes. Curable groups are introduced onto the bio oil through functionalization reaction with cyclic anhydrides such as maleic anhydride, citric anhydride, phthalic anhydride, succinic anhydride, methyl succinic anhydride. Wood adhesives are formulated with the functionalized bio oil by addition of water and curing agents. Two-ply plywood samples were prepared following the ASTM International Standard 2017, D2339-98 and cured on a hot press between 190-200° C. for 3-4 min under 3 MPa pressure. The plywood samples have dry and wet strengths in the range of up to 3.5 MPa with over 80% wood failure.

High concentrations of recycle polymer are gasified in a partial oxidation gasifier to make a syngas useful to make a variety of chemicals and polymers, such as cellulose ester. Polymers such as cellulose esters can be made that are obtained from sustainable sources, recycle sources, and are biodegradable. Circularity in the manufacture of textiles and/or plastics made from the fibers of such cellulose esters can now be achieved. The process of making such a syngas from high concentrations of recycle polymer (e.g. textiles and/or plastics) includes campaigning for the production of syngas.
