Abstract: A waste stream of organic matter such as sewage, plant and plastic matter is received for recycling and treated with high temperature and pressure to generate useful organic products such as bio-oil and gas. Byproducts such as char and an aqueous phase including water can be selectively recycled or beingly discarded. An oxidant added to a reactor containing waste from the waste stream facilitates an autothermal reaction under the temperature and pressure applied to the reactor, boosting the temperature slightly from the reactions therein. The reactor generates useful hydrocarbons such as bio-oil resulting from disruption of organic bonds. A combination of oxidation and radical initiation results from the oxidant, and provides an increased yield of bio-oil while decreasing char when compared to temperature and pressure alone. A stoichiometric quantity of the oxidant limits complete conversion of carbon into carbon dioxide by limiting available oxygen and therefore favoring hydrocarbon formation.

Abstract: A dustpan is disclosed. The dustpan include a debris receptacle coupled to the grip, having a debris collection surface and a bottom surface, and a roller mechanism, wherein the roller mechanism includes a roller with an adhesive surface, a biasing member, and a handle to apply a force coupled to the grip, wherein application of force to the handle moves the roller from i) a non-contact position, above the bottom surface of the debris receptacle, to ii) a contact position, configured to be one of below the bottom surface of the debris receptacle or ground level, and wherein once the force is released the biasing member returns the roller to the non-contact position.
