Abstract:

Some embodiments of the invention include a process for separating rubber, resin and bagasse from at least a portion of a rubber producing plant including the steps of providing a plant portion and at least partially homogenizing the plant portion in the presence of a resin-solubilizing medium, and extracting rubber using a rubber solubilizing solvent. In some embodiments, the plant portion can include an antioxidant, that in some embodiments, the includes a substantially non-staining antioxidant. Some other embodiments include a process for separating rubber, resin and bagasse from a rubber producing plant comprising the steps of providing a plant portion and applying at least one antioxidant to at least a fraction of the plant portion, milling the plant portion with a milling solvent, and separating rubber form resin using phase separation fractionation. Some embodiments include separation of bagasse and resin components and one or more solvent recovery steps.
