Currently in Russia, great importance is attached to actual issues of energy saving and energy efficiency in construction. Valid regulations require addressing issues related to improving the energy efficiency of buildings. The development and manufacture of new types of effective thermal insulation materials is one of the ways to solve assigned tasks. The use of industrial waste from mining and processing plants as a filler for polyurethane foam is considered in this paper. Samples from the filtration field of the tailings of Stoilensky GOK from various sites are taken as the studied raw materials; their granulometric, chemical compositions and harmonic diameters of the filler particles are determined. According to the calculation results, the dependence of the foaming coefficient on the average harmonic diameter of the filler is determined. The experiment-planning matrix is developed; according to its results, mathematical models are constructed for the dependence of the foaming coefficient of laboratory samples of polyurethane foam filled with tails. Three tail zones based on the results of sampling are considered. Analyzing the obtained results, a quantitative and qualitative assessment of the influence of each factor individually and their combination on the change in the “composition - properties” system is derived.

Construction and demolition waste (C&D waste) are widely recognized as the main form municipal solid waste, and its recycling and reuse are an important issue in sustainable city development. Material flow analysis (MFA) can quantify materials flows and stocks, and is a useful tool for the analysis of construction and demolition waste management. In recent years, material flow analysis has been continually researched in construction and demolition waste processing considering both single waste material and mixed wastes, and at regional, national, and global scales. Moreover, material flow analysis has had some new research extensions and new combined methods that provide dynamic, robust, and multifaceted assessments of construction and demolition waste. In this paper, we summarize and discuss the state of the art of material flow analysis research in the context of construction and demolition waste recycling and disposal. Furthermore, we also identify the current research gaps and future research directions that are expected to promote the development of MFA for construction and demolition waste processing in the field of sustainable city development.

e-Waste is generated at the staggering rate of 6.1 kg per person. In 2016, 44.7 million tonnes was generated globally, and the amount is estimated to reach 52 million tonnes annually by 2021. The management of this huge quantity of e-waste is a major problem across the world, primarily in developing countries. An effective e-waste management system is linked to the sustainability of e-waste processing plants, and currently it is plagued with different supply chain network (SCN) issues. To address the issues and challenges of SCN, there is a need to prioritize and address the constructs. The study thus combines two multiple criteria decision making (MCDM) tools, the analytical hierarchy process (AHP) and quality function deployment, to prioritize the constructs identified from literature and supported by field studies. The house of quality (HOQ) has been used for analyzing different stakeholders’ requirements. The degree of importance for HOQ-1 has been derived using the AHP tool. The study revealed the most intriguing issues and challenges of e-waste processing plants considering the requirements of different stakeholders. The results showed formal collection, storage, semi-informal collection, and e-waste quality to be the major issues of processing plants. The findings obtained from MCDM analysis have been validated though two case studies in India and China. If the results obtained are applied to the existing e-waste SCN, a holistic e-waste management system can be achieved for developing countries.

Waste Transfer

The Waste disposal techniques have become quite old for the modern period lately. The transfer of waste from the waste bins in the localities through the use of compactor trucks needs to be changed. It stands low on the efficiency scale. This can be improved by Channelizing waste through a separate corridor. The idea is to channelize the waste underground by using belt conveyor systems. The waste collector bins in the localities will be joined to the main conveyor heavy duty belts by small conveyor belts to move the waste. This waste will be taken to the waste processing plants by the belts fixed underground. The waste collector bins will be equipped with the pressure plates and will be connected to the network. As soon as the bin is full, it will send the information to the control centre. The operator at the centre can empty the bin by clicking a button. This will help to live monitor the waste and move it as soon as possible. The waste which is channelized can be easily segregated at the end where it enters the waste processing plant. Segregation of the waste will allow us to reuse the recyclable materials which most of the time are dumped in the landfills. The idea is to eliminate the Compactor Trucks as they cause pollution and congestion. Also many a times, waste materials are dropped out from the truck while carrying them to the processing plants which affects the riders behind it. The smoke from the trucks is dark and sooty which are the main causes for the lung diseases. Whereas the belt driven system will work on electricity. This energy can be harnessed by renewable energy resources or by power plants where the efficiency is the highest. The concept of underground tunneling in a well-planned layout is needed for laying of the sewer lines as they require heavy earth digging. Hence this underground waste transfer tunneling system can also be well established during the sewer line excavation work and can be implemented for the new smart cities which are going to be built. The efficient functioning of this system will save fuel, energy, time and creates an ecofriendly environment by cutting the carbon footprint.

Waste Accumulation

Continual growth of waste accumulation volumes, in particular, of solid domestic waste (SDW), causes a great many of environmental and economical problems such as, environmental (soil, groundwater and air) pollution, alienation of lands, alteration of landscape, growing expenses for construction of new waste processing plants and reconstruction of existing ones, etc. These are the actual problems in the cities and settlements of Russia and many other countries. The most part of SOW generated in Russia (97 %) is removed to the dumps and landfills and only 3 % is treated in waste processing plants. So, main attention should be concentrated on all the reduction of waste amount removed to the landfills which may be reached by means of development of environmental friendly wasteless or little waste technologies, in particular recycling systems introduction (organization of separate waste collection in situ, subsequent utilization of each useful SDW morphological components) and new waste processing plants construction. It should also take care of unauthorized dumps elimination, improving environmental conditions around the landfills, and engineering infrastructure safety provision. Besides, SDW consisting of organic materials for 50-80% may be considered as important additional source of energy. In particular, as to landfills, it is the power ofbiogas, which may be used for heating, electricity generation and several another purposes. The main expenses for biogas utilization are to extract, dry up and transport.
