Geus, Lucio Marcos de (2016) A support model for defining the location of voluntary delivery points for small construction and demolition waste generators. PhD thesis, Pontifícia Universidade Católica do Paraná, Brazil.
Abstract
Construction and demolition waste (CDW) represents the largest part of urban solid waste and, in many cases, does not have proper destination, causing environmental and public health problems. In many countries and also in Brazil, the management of this waste prioritizes non-generation followed by reuse, recycling and deposition in landfills. In order for the CDW to be recycled, the inspection of generator activities is necessary, but even more important is the creation of an efficient collection network. The control of CDW destination by the public agencies is viable in legalized building sites which, in general, are the largest ones managed by construction companies. However, most of this waste is originated in small sites in which the construction is managed by the property owner who builds, expands or remodels their place informally, making the control of their actions by the legal instruments inefficient. In order to prevent the wrong destination of this part of the CDW, the Brazilian law provides for the installation of a net of voluntary delivery points (VDP) in all cities of the country. It is very important that the VDP become attractive to the small waste generators and be well located within the urban area so that they work properly. This thesis aims at elaborating a support model for the definition of VDP location in the cities. A study on CDW management in Brazil and in other countries was carried out, which resulted in the presentation of VDP as a solution to the collection of CDW from small generators. The development of the model started with a revision of the decision support methods, which were employed in the research carried out with: managers of VDP already working throughout the country, small CDW generators and experts in the area. The data collected supported the definition of: the ideal kind of VDP to be implemented in cities, the necessary number of VDP and the main criteria regarding the location of collection/delivery points. The model was developed aided by a Geographic Information System (GIS) and the use of hydrographic, relief, road system, preservation areas and population density, zoning law and urban area maps of Ponta Grossa city in the state of Paraná. The city was chosen due to the availability of georeferenced information and the fact that it presents characteristics of size and relief which challenge the model. The result was a map with the location of the VDP network distributed throughout the city urban area. Finally, the study led to the conclusion that the mode proposed is efficient, its application is simple and it can be applied to other cities as an auxiliary tool in the VDP network implementation.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
