Key technologies of layout design of recycling plants of waste refrigerators

The present situations of waste refrigerators recycling and disposing were analyzed. Three key technologies of layout design of recycling plants of waste refrigerators were presented as follows: 1) establishment of recycling process of waste refrigerators; 2) the general plane layout of recycling plants; 3) the detailed layout of workshops of recycling plants. The focus of the three key technologies is to tackle the problem of the detailed layout of workshops of the recycling plants. By adopting Petri net, the model of logistics system of workshops was established and then optimized, and finally the detailed layout chart of recycling plants was gained. By adopting E-factory, the recycling plants were simulated. The results show that the method mentioned is effective.

The geographies of a more just food system: Building landscapes for social reproduction

Within the lifetime of a generation of people now involved in work in the cattle and beef industry in South Dakota, the landscapes of social reproduction that support and give shape to life for people there have been rearranged. Many of the social and physical relationships that developed to support smaller-scale, diverse farms and their surrounding communities are being made redundant by a new system of beef production and retailing. The costs of these redundancies are felt in dwindling small towns and an ever sparser rural population. Considering these changes as parts of landscapes of social reproduction is a means to connect the political and corporate logic driving our food systems to the spatial production of difference in the conditions for livelihood, as well as the spatial production of livelihood itself for both producers and consumers. Such an analysis is necessary in order to address the injustices inherent within our current food system.
