FIG. 1A is a perspective view of one of units 101, and FIG. 1B is a perspective view of two separated units 101. FIGS. 2A-C are high level schematic illustrations of bag 100 with two separable units 101 according to some embodiments of the invention. FIG. 2A is a top view of attached units 101, and FIGS. 2B-C and 4 are perspective views of two attached units 101. FIG. 2D is high level schematic top view illustration of bag 100 with four separable units 101 according to some embodiments of the invention


Each unit 101 is a distinguishable volume or pocket in bag 100 which may be used to contain a different type of waste (e.g., dry waste, wet waste, organic materials, different types of packages, bottles, paper etc.).


Bag 100 comprises at least two separable units 101. Each separable unit 101 comprises a top opening 104 having an opening circumference 105. Opening circumference 105 may be horizontal (e.g., FIG. 2B) or opening circumference 105 may have a horizontal dimension 106 and a vertical dimension 107 (e.g., FIGS. 1A, 1B).


Separable units 101 are attached to each other by a perforated attachment region 110 extending along at least a section of opening circumference 105 of each unit 101. For example, perforated attachment region 110 may be linear (e.g., FIG. 1A) or angled (e.g., FIGS. 1B, 2B, 4). Perforated attachment region 110 may comprise a section of horizontal dimension 106 and/or vertical dimension 107 of top opening 104. The location of perforated attachment region 110 may vary between pairs of attached units 101 in a single bag 100. Perforated attachment region 110 may further comprise extensions 108 that extend beyond the volume enclosing part of units 101 (see FIG. 1B). Openings 105 may be planar or non-planar, and of any form, e.g., round, square etc.


Units 101 may be separably attached to each other only at their top portions 102 near their openings 104, and be free and not connected to each other along most of their lengths (bottom portions 103). For example, bottom portion 103 of unit 101 may comprise 50%, 70%, 80% or 90% of their length. In an example, perforated attachment region 110 may be horizontal at the surface of openings 104, and thus units 101 may be unattached at over 90% of their length or even be free along their complete vertical length.


Bag 100 may further comprise handles, e.g., along perforated attachment region 110, in proximity thereto or apart from perforated attachment region 110. In an example, each separable unit 101 may comprises at least one handle 91 at perforated section 110 of opening circumference 105 and at least one handle 92 at an imperforated section of opening circumference 105 (see FIGS. 1A, 1B, and 4).


Advantageously, bags 100 may be produced as one piece, using commercial production methods, and require no additional mechanical means for separating units 101 apart from a simple perforation of the designed attachment regions 110.


In certain embodiments, bags 100 may have any form and be made of various bag materials. For example, bags 100 may be produced of polyethylene, nylon or any plastic material. Bags 100 may be produced from paper, cardboard or any other processes natural material. Different unit 101 of one bag 100 may be made of different materials, e.g., some (or all) of units 101 may be made of recyclable material. In an example, units 101 may have different colors, which designate the types of wastes belonging in each unit 101 (e.g., a dry waste unit may be green, and a wet waste unit may be brown). Unit colors may also be arbitrary, artistically designed or be used for advertisements. In certain embodiments, bags 100 may be flexible or, e.g., rectangular, and stiff. Bags 100 may be produced from various foils, e.g., aluminum foils.


In certain embodiments, units 101 may be sealable. In certain embodiments, units 101 may comprise fasteners or frame members arranged to allow easy attachment of bag 100 to a container, such as a home container or a public waste container. Bags 100 may be arranged to fit any type of waste container. Units 101 of bag 100 may have different sizes.



FIG. 4 illustrates an additional bag structure, with perforate attachment regions 110 being somewhat lower than opening circumference 105. Additionally, attachment regions 110 is not at the surface of unit 101 but perpendicular thereto, a configuration which may have mechanical advantages.



FIG. 2D is high level schematic top view illustration of bag 100 with four separable units 101 according to some embodiments of the invention. Any number of unit 101 with equal or different sizes may be designed in bag 100. As illustrated in FIGS. 2C and 2D, bag 100 may further comprise a margin 115 designed to enable attachment or mounting of bag 100 in a container while keeping openings 104 of units 101 substantially planar. Margin 115 may also be designed to protect perforated attachment region 110 from premature separation and damage. Margin 115 is also illustrated in FIG. 4, in which it also mechanically stabilizes bag 100 and helps maintain circumference 105 at one level as the bag's opening.



FIG. 3 is a high level schematic flowchart of a method 200 of waste sorting according to some embodiments of the invention. Method 200 may comprise any of the following stages: designing and/or producing a bag to have separable units attached to each other by a circumferential perforated attachment region (stage 210); using the bag to manually sort waste at home or public containers (stage 220) and separating the units upon waste disposal (stage 230). Method 200 may comprise sorting home waste by using bag 100 to segregate different waste types to different units. Method 200 may further comprise designing a bag margin to enable attachment or mounting of the bag in a container while keeping the top openings of the units substantially planar (stage 225).


Advantageously, bags 100 simplify waste sorting and make it more accessible, for example by disposing with the need to hold and maintain separate containers for different types of waste. For example one of units 101 may hold wet waste and another unit 101 may hold dry waste, while bag 100 is in a single container. In an example, the dry waste unit may be larger than the wet waste unit, e.g. in a 4:1 ratio.


Advantageously, bag 100 solves the problem of the excessive space taken up by separate containers used today for waste separation. In home use, dealing with several waste containers discourages private persons from recycling their home waste. At the house or municipal level, the necessity to set multiple garbage containers also requires a lot of space, a requirement which deters wide acceptation of the recycling paradigm Proposed bag 100 and waste sorting method 200 can alleviate these hindrances and allow effective recycling without excessive space consumption.


Waste sorting is then carried out simply by separating units 101 upon waste disposal. Unit separation is structurally arranged to be simple and to prevent damage to separate unit 101. In particular, the top attachment which leaves most of the bag unit free from each other protects the units from being torn or damaged by the separation.


In certain embodiments, each bag 100 and/or unit 101 may be barcoded and may be used to reward recycling citizens.


In certain embodiments, bag 100 further comprises an air freshener or a deodorizing composition in one or all units 101 (e.g., in a wet waste unit).
