Waste management is an important element of environmental protection in each country. Vegetable and fruit waste are produced in every place in the world, hence it is necessity to manage it. Legal regulations in Poland forbid the storage of this waste which were selectively collected. Therefore, it is necessary to looking for other methods of their management. Agricultural biogas plants are an important source of renewable energy. In last years, in Europe, the most important substrate used for biogas production was...

The main cause of excessive waste generations is irrational resource management. Waste collected on landfills can be used to a large extent as secondary raw materials, valued at several hundred million dollars. In material management, the use of raw materials and materials from recovery is more and more important. Many materials of mineral organic origin are returned to the production in the form of secondary raw materials. The utilization of waste means that in industrialized countries, the demand for materials i...

In this study, the potential use of dam tailings (DT15 m., DT40 m., DT65 m.) of a copper mine for paste backfill material was investigated. Cemented paste backfill (CPB) samples were subjected to the uniaxial compressive strength (UCS) test at 7-14-28-56-90-180 days of curing ages. A total of 378 CPB samples were prepared at different binder dosages of 5.5?11.0 wt% by dry weight to determine an optimum CPB mixture with a target UCS of ?1.0 MPa over a curing period of 28 and 90 days. The strength development of CPB...

This paper presents the analysis of quantities and types of waste delivered to port reception facilities by passenger-cargo ferries at the Port of ?winouj?cie. The waste classification set out by applicable legal provisions, statistics on the numbers and sizes of vessels delivering waste to the port and journey frequencies of the vessels under review have been used, along with other inputs, for the purposes of this study. The objective of this paper has been to conduct an analysis of quantities and types of waste ...

The paper examines the waste management issues in the villages annexed to administrative-territorial units of the Romanian cities which have been frequently neglected by urban waste operators. The lack of waste collection services in such peri-urban communities favored the illegal waste disposal practices particularly prior to EU accession. The extension of waste collection services from main cities to such areas is compulsory in order to mitigate the environmental risks and the public health threats. The paper es...

Environmental safety is part of the country's national security and is provided through legal and economic instruments. One of the main threats to the ecology of Russia is the consumption and production waste. The article deals with the legal and regulatory framework for the implementation of activities in the area of waste disposal in the Russian Federation, and outlines the main principles of economic regulation in the field of waste management. The analysis of environmental taxes and payments related to waste m...

This paper presents the problems of ship-generated waste management in port areas. The first part contains a classification and characterisation of ship-generated pollution, with a particular focus on waste and cargo residues. Further to that, the legal and documentation aspects of waste management in seaports are discussed, along with the basic principles of rational waste management. The second part of the paper presents a diagram of the waste management model within a port area and analyses each individual stag...

Trends in waste generation show an increase in the volumes of waste produced worldwide. Currently, municipal solid waste management is one of the primary tasks for environmental authorities in Poland due to industrialization and economic growth, growing income, and an increase in quantity and variation in the types of waste generated. Conventional treatments of municipal solid waste using landfilling have become more difficult and expensive in Poland due to land deficiency and new environmental policies. The objec...

Despite the existence of many technologies allowing for recovery of coal combustion products (CCPs), they still remain a product that is problematic enough, with their industrial use in the world lying in the range 40-60%. The remaining CCPs produced in the energy industry end up in landfills or are stored, thus losing their property. One of the main directions of CCPs recovery has been, for many years, the underground mining industry, where they are used, among others, as fillings in mining excavations, component...
