Collective sorting

Beckers, et al. [beckers94], have introduced a simple distributed sorting algorithm that is inspired by the self-organized way in which ant colonies sort their brood. 

Implemented by robot teams, their algorithm has the robots move about a fenced-in environment that is randomly littered with objects that can be scooped up. These robots (1) move randomly, (2) do not communicate with each other, (3) can perceive only those objects directly in front of them (but can distinguish between two or more types of objects with some degree of error), and (4) do not obey any centralized control. The probability that a robot picks up or puts down an object is a function of the number of the same objects that it has encountered in the past. 

Coordinated by the positive feedback these simple rules induce between robots and their environment, the result, over time, is a seemingly intelligent, coordinated sorting activity. Clusters of randomly distributed objects spontaneously and quite naturally emerge out of a simple set of autonomous local actions having nothing at all to do with clustering per se.

The problem with post-consumer plastics is their immense variety and widespread application. One tonne of plastics can be converted into either 20000 two-litre drinks bottles or 120000 carrier bags Collecting, sorting, baling, and transporting such numbers of lightweight materials is a tremendous task, with typical cost levels as shown in Table 1.10. 

The waste plastics utilized at the SPR plant are the household waste plastics specified by the Containers Packaging Recycling Law and marked as recyclable on the each of the products. The waste plastics are discharged at curbside by residents once per week, and collected, sorted, compacted in bale form by the local government, which then snpplies the SPR plant. 

It has been common practice for many years to collect and recycle spent lead-acid batteries because of their value as a major source of lead units. This has led to highly developed operations whereby batteries are collected, sorted, and delivered to the secondary smelter for recovery of the lead and other materials of value. 

The SCRELEC collection process is very similar to that operated by GRS Batterien in Germany. Collection boxes of various types are distributed to collection points. Currently two waste management companies have been contacted to collect the batteries from the various collection points including stores, business or industrial sites and municipal waste facilities, and forward them to a sorting facility. This scheme is co-ordinated via a national call centre. SCRELEC has released an invitation to tender for the collection sorting and recycling of batteries in France.

As Muthu et al. (2012a) describe, more work is needed to accurately assess environmental benefits of integrating recycled materials into new products. The sheer diversity in textile types leads to difficulty in separating fibres for efficient recycling, with the energy expended to collect, sort and manufacmre the shoddy into a new product complicating the analysis.

Successful recycling involves the four phases of collection, sorting, reclamation, and end use. (a) True, (b) False. 

The four parts to successful recycling are collection, sorting, reclamation, end-use. Unfortunately, collected materials will not be sorted or reclaimed if the supporting infrastructure for processing doesn t exist.
