  • Publication number: 20250043508
    Abstract: In some variations, OCC is screened, cleaned, deinked, and mechanically refined to generate cellulose nanofibrils. The OCC may be subjected to further chemical, physical, or thermal processing, prior to mechanical refining. For example, the OCC may be subjected to hot-water extraction, or fractionation with an acid catalyst, a solvent for lignin, and water. In certain embodiments to produce cellulose nanocrystals, OCC is exposed to AVAP® digestor conditions. The resulting pulp is optionally bleached and is mechanically refined to generate cellulose nanocrystals. In certain embodiments to produce cellulose nanofibrils, OCC is exposed to GreenBox+® digestor conditions. The resulting pulp is mechanically refined to generate cellulose nanofibrils. The site of a system to convert OCC to nanocellulose may be co-located with an existing OCC processing site. The nanocellulose line may be a bolt-on retrofit system to existing infrastructure.

  • Publication number: 20250027688
    Abstract: Examples of the present disclosure relate to systems and methods for providing hot water for a hot water heater and heating capacity for a climate control system by utilizing a Stirling heat pump system. The Stirling heat pump may be partially integrated into an indoor unit of the climate control system and a hot water heater. An additional indoor heat exchanger may receive heating fluid from the Stirling heat pump system to provide heating capacity in addition to another indoor heat exchanger of the climate control system. Further, the heating fluid circuit of the Stirling heat pump system may be partially integrated into a hot water tank for heating water. A controller may direct the flow of heating fluid from the Stirling heat pump to the hot water tank and/or the climate control system based on a request for heating.

  • Patent number: 12077915
    Abstract: 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.
