This description relates to the field of recyclable material treatment systems. More particularly, this description relates to systems which are capable of treating many types of materials.
The disposal of solid waste has become increasingly difficult for municipalities as landfills close down and environmental laws further reduce or eliminate options such as incineration. It has become increasingly obvious that recycling is the most viable alternative to conventional solid waste disposal procedures used in the past. Recycling offers an environmentally friendly means for disposing of solid waste while at the same time providing resources for manufactures of such as paper, plastic, glass, metal, compost, textile and so on, which are so critical to our daily lives.
Furthermore, one major problem of the actual recycling process is the cost of material separation. Waste management facilities cannot, or will not bear the cost of accurate material separation, for various reasons. A high percentage of recyclable materials are redirected to dump sites. Consumers do not wish to make the efforts required to separate recyclable materials by category. Consequently, the number of landfills continues to grow, natural resources are consumed quickly, and demanding recycling efforts go wasted.
The piled refuse usually resembles messy clutter or mounds of garbage, an undesirable sight to see, especially in a frequented area. The containers also easily overflow with the load of recyclable items and stay so several days. With time and temperature dirty waste develops many microbial activities. The overflowing items often intermingle, causing contamination of the recyclable materials, hazardous sanitary situation and unwanted smells.
Furthermore, households that aggressively sort their recyclables often become overwhelmed by bundles of papers and large bags of cans, glass and plastic bottles which have to be further separated depending on whether or not they required a deposit. Manually crushing plastic containers and cans is a hassle and inefficient and furthermore are not available on the market yet. These bags and bundles are then placed curbside where carters have to haul them to a recycling plant to process the waste products for recycling. The cost for hauling recyclables is sometimes overwhelming to the municipalities because of the unnecessary volume created by bottles, cans and the like that are in their original form resulting in a tremendous amount of the expense in carting recyclables coming from transporting the air contained in the containers. The cost for carting and processing these recyclables is then passed on to the consumer in the form of increased taxes.

There is therefore a need to overcome at least one of the drawbacks mentioned above which include, but are not limited to: a substantial reduction in the volume of discarded materials, easily sorting a substantial amount of discarded material in a reduced space, reducing the foul smell associated with organic waste or dirty inorganic materials, reducing the noise and energy consumption associated with traditional treatment machines, simplifying and increasing reliability in comparison with traditional treatment machines, etc.
There is therefore a need for improvements in the field of recyclable material treatment systems starting from the source.

The sink 101 receives every kind of organic waste and concentrates them to its bottom. Hot and cold water is provided to clean vegetables, hands, pots, etc. In the embodiment shown in
At the bottom of the sink 101, a hole 303 and a conduit 306 provide a passage for the organic waste to the low speed crusher input 301. Water flow from the sink 101 is useful to drain the materials. A sink magnetised cap may be used for safety reasons or any other means adapted for the same purpose.

The organic waste is crushed by the interaction of the blades 202 with the input opening 204 and is also moved by the blades 202 against the inside surface 205 of body 207. The organic waste travels inside the body 207 until it reached to the crusher output 205. It is understood that organic waste is pulled, pushed and crushed repeatedly by the successive blades. On the bottom left of crusher 200, crushed waste is released by gravity through the crusher output 205 and falls into a receptacle 105. On the bottom inside of the conduit 306 there may be a screen with a water bypass (not shown) through which flows out the excess water to the drain 308.
Blade assembly 206 rotates about a rotation axis 203 at a generally slow speed with high torque. The speed range may be between 30 rpm and 120 rpm, more specifically between 60 rpm to 90 rpm, while the torque may vary proportionately to the input power.
The distance between the blade 202 and the body 201 may be comprised between 0.5 mm to 1 mm. No sharpening is necessary neither for the blades 202 nor for the body 201. The input opening angle is shown to be 90 degree upward from horizontal. In other embodiments, the input opening angle can be up to 180 degrees from horizontal. The output opening angle a can be from 90 to 120 degrees. This is beneficial to reduce the vertical space occupied by the crusher 104 (
The receptacle 105 is set on gliding rails 307 to easily pull it out of the body 103 when it is full.

According to this embodiment, when the compression cycle is over, jaws 407 are separated and compressed materials fall directly into a selected one of the bins 110. Previously, the control device will have rotated the lower table to place the selected receptacle below the compactor output 404.
In another embodiment, the compactor 106 could be equipped with a binding baling system. When the chamber 403 of the compactor 106 is full of compacted materials such as compacted plastic, paper, cardboard, textile or other material, the bounding bailing system groups the ball with ties such as string, tie wrap, wire or any other suitable tying means. The balls could be manually pulled out of the chamber and easily moved.
