Apparatus for the hygienization of biodegradable municipal wastes comprising means for measuring temperature, measuring liquid levels, pressure sensors and distribution valves, the apparatus consisting of two hygienization columns, between which a water heating column is located, whereby the hygienization columns are composed of at least two above each other horizontally placed cylindrical hygienization tanks (1) interconnected by the first connecting pipes (2) with the filling inlet (15) in the upper hygienization tank (1) and outlet (16) of the processed material in the lower hygienization tank (1). A sludge pump (4) is included in the forced circulation branch (3) between the upper hygienization tank (1) and the lower hygienization tank (1). The water heating column for the hygienization tanks (1) is composed of at least two above each other horizontally placed cylindrical water tanks (5) interconnected by second connecting pipes (6) with cold water inlet (7) into the upper water tank (5) and the water shower system (22) piping through the heated water outlet (8) from the lower water tank (5) and a water pump (9). A system of heat exchangers (10) placed inside the hygienization tanks (1). The hygienization tanks (1) have a built-in screw mixing system (14) and microwave two-band heating sources (20) are associated with the hygienization tanks.

A container for collecting and storing biodegradable waste comprises a casing (11) having a cassette (20) forming a loading chamber (24) at the top of the casing for waste (70). The cassette holds a tubular liner (30), which is fed through the chamber. The bottom of the chamber is formed by sealing flaps (18), held closed by a mechanism (40). The mechanism is movable downwardly to release and open the flaps and has trap doors (41) which carry the waste and clamp the liner. Camming devices (60) effect opening of the trap doors on return upward movement of the mechanism, to unclamp the liner and permit waste to fall into the liner below the chamber (24).

A biodegradable lawn waste collection system is provided. The system generally includes a waste receiver, a shaping insert, and a handle. The waste receiver may comprise a mesh structure having a filling end and a sealing end. The mesh structure may be formed from a biodegradable polymer composition. The shaping insert is configured for removable reception within the filling end of the waste receiver. The shaping insert provides the waste receiver with rigidity and stability when filling the waste receiver with lawn waste. After the waste receiver has been filled with lawn waste, the shaping inert is removed and the filling end is secured, such as by tying a knot. The full waste receiver is then releasably attached to the handle, which enables the full waste receiver to be easily carried or dragged to a desired destination.

An apparatus for collecting and disposing pet waste that includes a biodegradable plastic bag and either one or two built-in disposable collection aids. The user grasps the lower closed end of the bag while also grabbing the built-in disposable collection aid. The bag is then inverted over the user's hand and forearm, providing protection from the pet waste and exposing the built-in collection aid. The collection aid's leading edge acts as a scoop and facilitates scooping up the pet waste. The bag is then inverted once again to its original position and optional handles are tied to close the bag.
