One of the possible innovative ways how to process and utilize waste is its pyrolysis in the pyrolysis unit Pyromatic 250. The tests were conducted by Ostravsk? LTS, a.s. in laboratory conditions in the ENET Center of V?B-TU Ostrava. The input material was provided by MEVAPACK, s.r.o. Pyrolysis is a thermal decomposition of organic substances without access of oxygen. This decomposition produces three fractions ? liquid fraction, gaseous fraction and a solid residue. These can be used for heating of the pyrolysis ...

The purpose of creating National Parks is to restore the proper state of nature in a given area. An attempt to recreate distorted landscape values is a long, arduous and expensive process. Part of the Parks? operating costs is covered from admission fees for tourists to enter their areas. However, to prevent negative impacts of visitors on the natural environment, visiting National Parks is subject to particular restrictions. Tourist traffic is carried out only according to specific rules resulting from legal prov...

The production of a titanium sponge obtained by the reduction of titanium tetrachloride by magnesium is accompanied by the formation of a huge amount of chloride waste. They are annually stored in landfills - storages, polluting the environment. Consequently, one of the topical problems of titanomagnesium production is the processing of chloride waste. In Kazakhstan, there are a variety of sources of chloromagnesium raw materials for the electrolytic production of magnesium, but they are not used in the magnesium ...

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 recent years, the packaging market has become an important element of the economy of many countries. Its growing importance is associated with rapid industrial development, globalization, free transfer of goods and growing demand from consumers. Customer requirements affect the growing demand for more functional, colorful, light, flexible, ecological and environmentally safe packaging. Currently, the packaging has become an element that in many cases determines the demand for a given product. In particular, thi...

The purpose of the researches undertaken finds it origin in the scientific and practical concerns regarding the accumulation of knowledge with regards to the characteristics of the natural frame and of the social-economical particularities as elements which define the structural frame in the waste management and of the possible pressures upon the quality of the environment. The importance of the subject tapped derives from the fact that besides the food, clothing and wood necessities, the natural environment (soil...

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 relevance of the study is due to the growing environmental problems faced by modern society and the need for their urgent resolution. The decline in production did not lead to a reduction in the negative anthropogenic impact on the environment, since in an unstable environment many enterprises save on environmental measures. According to most experts, the limits of economic growth are not so much related to the limited resources as are due to the inability of the environment to independently process waste of h...

The use of secondary resources and waste is the most important source of expanding the raw material base in the production of various building materials. Nowadays, there is an increased interest in technogenic industrial waste containing aluminum oxide, and in combination with technogenic materials containing sulfates, there is an increased interest, because their use makes it possible to obtain sulfoaluminate cements. The use of technogenic materials requires the carrying out of survey works both for the developm...

Product manufacturing continuously increases despite of complicated relations and unstable world economics. Various forecasts of development in industry show that in future the consumption should not decrease; on the contrary, it should slightly increase. This happens even despite of minimization in industry. But production processes present environmental charging for any company, acting in given sector. Treatment of waste is important for producers of all kind of waste, as well as for consumers that are producing...

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...

This paper presents a solution for the replacement of conventional fuels with biofuels in order to protect the environment. The proposed biofuel is formed of diesel and a certain amount of animal fats. Biodiesel is similar to diesel fuel but with small differences. The animal fat is the result of the skin processes in the leather industry. In this industry it represents a waste and it is not used. We can consider that the animal fats are a renewable biofuel source. The proposed fuel has the properties of a renewab...

Bread products industry is one of the main branches of food industry. Taking into account the final products and their great diversity, they are divided from the scientific point of view in three categories such as: bread and bread products, pastry and specialty products (biscuits, donuts etc.), these constituting products categories that are consumed daily in quantities that depend on the consumption preferences of the population. In Romania, are consumed as a medium value 95 kg of bread per consumer per year, co...

Plaster and composites made up of gypsum have been extensively used in building for various purposes. This work aims to study the use of polypropylene (synthetic polymer), Alfa (Stipa tenacissima ) and plastic waste as fiber in the manufacture of plaster and mortar plaster . In this study, a Superplasticizer was used to improve the fluidity of the plaster grout and mortar plaster. The optimization of the dosage of superplasticizer of plaster grout without fiber was determined based on the mechanical strength tests...

The paper is a review of the current situation of waste management in Romania, focusing on solids recovery and recycling. Although some efforts have been made in the Romanian waste sector in order to reach the European targets within the deadlines, the national waste management plan update and waste prevention program implementation are delayed. At the moment, public awareness campaigns are being developed and implemented for recycling, without much emphasis on reduction. However, for now most of the waste ends up...
