The present invention provides a pulp product (e.g., paper) comprising cellulose and nanocellulose, wherein the nanocellulose is derived from the cellulose in a mechanical and/or chemical step that is separate from the main pulping process. The pulping process may be thermomechanical pulping or hydrothermal-mechanical pulping, for example. The pulp product is stronger and smoother with the presence of the nanocellulose. The nanocellulose further can function as a retention aid, for a step of forming the pulp product (e.g., in a paper machine). Other embodiments provide a corrugated medium pulp composition comprising cellulose pulp and nanocellulose, wherein the nanocellulose includes cellulose nanofibrils and/or cellulose nanocrystals and the nanocellulose may be hydrophobic. The nanocellulose improves the strength properties of the corrugated medium. In some embodiments, the cellulose pulp is a GreenBox+® pulp and the nanocellulose is derived from the AVAP® process.

Methods and apparatus for economically producing a biodiesel product from feedstocks. Some embodiments comprise using at least one of a crude feedstock pretreatment process and a free fatty acid refining process prior to transesterification and the formation of crude biodiesel and glycerin. The free fatty acid refining process may include introducing the feedstock to glycerolysis to obtain a glycerolysis product then stripping the glycerolysis product to produce a fatty acid distillate and a stripped feedstock. The fatty acid distillate is recycled to the glycerolysis process to create more higher-molecular weight glycerides and the stripped feedstock (mostly di- and tri- glycerides) proceeds to transesterification to make biodiesel.
