Abstract: An apparatus and system for storing and collecting separated solid waste. The apparatus is a chambered container which includes a container body defining a first chamber for receiving a first waste, and a lid covering an open end of the body. The lid includes a base portion for defining a second chamber for receiving a second waste and a cover for covering the base portion. The system further includes a collection vehicle divided into two compartments, a robot arm for hoisting the chambered container up and over the vehicle, and a pair of guide rails for engaging the lid of the container for causing the contents of the first chamber to fall into one compartment of the vehicle and for causing the contents of the second chamber to fall into the other compartment of the vehicle.

Abstract: A trash bag for recyclable waste which will eliminate a second collection of recyclables and having color or another type of code thereon to permit the bag to be identified and separated from trash bags containing ordinary trash, and a system and method for collecting recyclable waste. The trash bag is designed to be placed in the normal trash collection stream along with bags of ordinary trash and to be delivered to an existing landfill or incinerator or to another separation location at which identification and separation of the bags from the bags of ordinary trash is accomplished. According to the invention, identification and separation of the bags of recyclable trash can be performed manually or in an automated manner at the landfill, incinerator, or other separation location.

Abstract: Mono- and di-2-hydroxyethane sulfonate derivatives and 2-aminoethane sulfonate derivatives of C.sub.21 -cycloaliphatic dicarboxylic acid having the general formula ##STR1## where x and y are integers from 3 to 9, x and y together equal 12, R is ##STR2## and M.sup.+ is an alkali metal, ammonium or amine cation, are disclosed as emulsion polymerization emulsifiers.
