Thermochemical platforms different technology than biological (which tries to recover things of value from biomass ie. Lignins, sugars fatty acids) This breaks it all down to building blocks and rebuild it Combustion,reforming and separation offinal products Can end up with liquid product (bio-oil) or gases. Bio-oils are Unstable because it lacks hydrogen Fix by process called hydroeoxygenation o adding hydrogen and removing oxygen o Not sustainable Gasification o Combustion without oxygen at high temp. 600-800* o End up with just gas products called syngas o Syngas: synthesis gas. Valuable because we know how to make a variety of products with it. Plasticization

Creating plastic-like products from super heated lignocellulose Now creating self coating materials o Ie. on wood pellets, so that you don’t need storage units to keep them out of the rain so they don't fall apart. With the coating, they can get wet and be fine to burn. Mix and match the different boxes in order to get to making the products we want Like a make-up pallet, use the colours you need to create your look. Bio products: Some products ready for market, others have a long way to go Food fibre lumber pulp and paper, products are out there already. Trying to make them better. Nanocrystaline cellulose: o first of nanocell products that they are working on o Could save a lot of energy and materials in the future. o Being piloted now, 5 yrs out. 10-15yrs out we will have other nanocrystaine products.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
