TECHNOLOGICAL AND LOGISTIC PLANNING OF ENVIRONMENTALLY SAFE SCHEMES FOR THE COLLECTION OF SOLID HOUSEHOLD WASTE

Mineral raw natural resources are not unlimited. Preservation of such non-renewable resources is the most urgent task of mankind. The development of non-waste technologies, the integrated use of secondary raw materials, which simultaneously reduces environmental damage - one of the ways to solve environmental problems. Utilization of wastes makes it possible to solve issues of environmental protection as well as resource saving. In the light of environmental requirements, building materials based on recycled materials, including cellulose-containing solid waste, have significant advantages over other traditional materials. Development of technology for obtaining new effective environmentally safe composite highly filled materials based on cellulose-containing solid household waste for the production of construction products is a rational link in solving the general problem of improving the environmental situation. In the article there are three main ways of combining gypsum binder with cellulose-containing solid household waste. Investigations were carried out on the effect of changing the ratio of cardboard / gypsum binder, specific pressing pressure, sequence of combination of components on the properties of the final product. The strength of the material was determined from the values of the flexural strength, the compression to complete destruction of the sample, and at 10% deformation. Studies have been carried out to increase moisture resistance. The results showed that the most optimal way of combining is the 2 way. The increase in moisture resistance is significantly enhanced by the action of organosilicon hydrophobisers.

Additional Costs

The ever-growing consumption of resources due to global population growth and dynamic development of industrial production led to the increase in the volume of waste generated, which in turn led to the reduction of areas suitable for disposal, and gave rise to the problem of efficient disposal and recycling of waste. In this situation, society needs to direct its development in a more environmentally safe direction and review existing production and consumption models. Solid municipal waste can become the main link in the chain of interrelated factors that need to be considered together with other global problems, such as the rational use of natural resources, since it is a rich source of secondary resources, a “free” energy carrier, due to the fact that garbage is a renewable carbon-containing raw material. However, such resource material is used in the most inefficient way — it is buried, which creates additional costs for cleaning up areas contaminated with waste. In this regard, the article proposes to test the resource approach in waste Management on a specific economic entity, namely, on the example of the Novosibirsk region. In particular, the authors consider the existing volumes of solid household waste in the region, typical problems, and opportunities to solve them using the resource approach.

And Storage

Vilnius City has two sanitary landfills, which are on operation now, one is Kariotiskes household waste landfill, started at 1987, second is demolition and construction waste landfill, ready to be closed. There are four closed and recultivated household waste landfills in Vilnius city and close to it. The main problems of closed landfils are the same as of working one - biogas leakage almost in all of them, what is not environmentally safe; another problem is leachate production, which is especially increasing in autumn and spring seasons in Kariotiskes and still is a problem in two closed landfills. Collection of recycleable materials was started at sources in 1994. Four fractions are collected : paper, glass, plastic and metal. In 1997 two special sites for collection of bulky waste were opened. Sorting of various recycleable materials at the landfill was started in 1992. The premises were built for sorting, packing and storage of saved materials. Paper, plastic metal , glass, wood, bricks etc. are collected there. The first row of Kariotiskes landfill - 10,5 ha area has reached 25-30 m high hill. It was closed in 1996. The recultivation project is on competition now.We are looking for a new site , which could serve for sorting, crushing and reusing of demolition waste.The problem is iron - concrete.

Abstract Mining and accumulation of industrial and household waste on the earth’s surface form the technogenic relief of the planet. The main forms of violation of the natural relief are quarries, ditches, landfills and spoil tips. There are two ways of landscape optimization in order to restore ecological balance, to turn the aggressive terrain into an ecological and economic value. The first is a return to the original natural landscape. The process is implemented by ground filling of technogenic depressions, removal and chemical and technological processing of waste accumulated at landfills and spoil tips. The second way is to use technogenic relief to form a new natural landscape. The main attention of the article is paid to the optimization of technogenic landscapes by forest plantations and forest reclamation. As a result of these activities, environmentally safe and aesthetically expressive spaces are formed. Most of these facilities have a high potential for economic, socio-economic and recreational use. The outstanding world achievements in this field are considered. Their ecological and economic characteristics are given.
