Opis:
In the coming years, the heating sector in Poland will undergo further changes as a result of the implementation of the country's energy policy within the European Union. Its main goals are: increasing energy efficiency, development of renewable energy sources and meeting legal and environmental requirements. Their implementation should take into account the observance of CSR principles in order to ensure a stable supply of heat to industrial and municipal consumers with high energy efficiency and limitation of the environmental impact. The article presents the conditions for the operation of the heating industry in Poland and CSR issues in heating companies. Particular attention was paid to the issue of energy poverty and its reduction. The application of social responsibility practices in heating industry on the basis of activities of selected enterprises in this sector was presented.

Opis:
The heating sector, which accounts for half of the EU's final Energy consumption, still relies heavily on fossil fuels. This results in the emission of greenhouse gases and other pollutants into the atmosphere. For this reason, the European Union has, for several years, been pursuing a climate and energy policy which, in the area of district heating, is intended to make it more efficient and sustainable. This means introducing low-carbon technologies and reducing fossil fuel consumption in favour of renewable energy sources. Modern efficient district heating systems should guarantee a reliable heat supply while reducing environmental impact. The article discusses the main factors important for the sustainable development of district heating. The potential and importance of the heating sector in the European Union member states was presented. Then, the factors affecting the development of this sector are shown and the directions of transformation of district heating systems with the use of renewable Energy sources are discussed. It also presents the current structure of fuels consumed by the district heating sector in Europe and its projected development with the use of high-efficiency cogeneration and various renewable energy sources.

Opis:
Heat supply is one of the most important sectors of the country's energy economy. Widely understood heating secures both: the living needs of society and industrial recipients. Modern heating systems should guarantee reliability of heat supply while limiting energy consumption and transmission losses. It results from the sustainable development strategy, implemented in the European Union, which is based on the development of renewable energy and improvement of energy efficiency. As a consequence of such an energy policy, investments and innovations are implemented in the two areas of the heating sector: technical infrastructure and management of the heat generation and transmission system. The article discusses legal as well as technical and economic conditions for the operation of heating companies, including aspects of energy security. The characteristics of the heat market in Poland and investment expenditures related to the modernisation of infrastructure and environmental protection has been presented in it. Selected innovations used in the process of heat production and supply have been described as well as modern technologies and IT tools that improve management of heating system. The possibilities and limitations of innovative heating development have also been indicted here.

Opis:
District heating networks are key components of efficient heat supply systems for municipal and industrial consumers. The purpose of the research presented in this article was to analyze the thermo-hydraulic parameters of the operation of a transmission main in a district heating network to improve the heat transfer efficiency. Based on a literature review of existing studies, the basic issues of the heat supply process were discussed, and selected methods and tools for simulating district heating networks were characterized. A detailed mathematical description of the phenomena occurring during heat transport in a district heating network pipeline was also presented. Then, analytical calculations and simulations were carried out for the selected district heating system using Termis software. Operational parameters collected in the actual district heating system were used as output data for analytical modeling. Pressure drops, power losses, and heat transfer efficiencies in the main buses at different outdoor temperatures during the heating season were determined. Selected results of the study were included, and possibilities for improving the efficiency of heat transfer in the studied district heating network were indicated.

Opis:
District heating, which accounts for half of the EU's energy consumption, still relies heavily on fossil fuels. This causes emissions of dust and greenhouse gases and into the atmosphere and leads to negative climate changes. For this reason, European Union countries have been implementing a climate and energy policy for many years, which in the area of heating is aimed at making it more efficient and sustainable. This requires the introduction of low-carbon technologies and the reduction of fossil fuel consumption by increasing the share of renewable energy sources. Modern, efficient and smart heating systems should guarantee reliable heat supply while reducing the environmental impact. The article discusses the direction of change and development of district heating systems through the introduction of innovative technologies. The new generations of 4GDH and 5 GDH district heating systems are described and the benefits of their use are indicated. The concept of smart district heating networks, their structure and the advantages of their implementation are discussed. The possibilities of creating smart energy systems using renewable energy sources and heat storage technologies were also indicated. The activities of Polish district heating companies in the introduction of smart heat networks are presented, based on research conducted.

Opis:
In 2015 the Agenda 2030 was introduced, framed of 17 sustainable development goals (SDG) with 169 targets, which were adopted by the United Nations Member States and should bring prosperity and growth to the global society. In this paper a focus is given to the SDG 12 Sustainable consumption and production from the e-mobility perspective. SDG 12 aims to ensure sustainable consumption and production (SCP) patterns – it is about promoting resource and energy efficiency, sustainable infrastructure, and providing access to basic services, green and decent jobs, and a better quality of life for all. Many stakeholders from public and private sector are investing a lot of effort to identify consumer behaviour for future improvements in development of their green products and strategies Because sustainable mobility and consequently low emission vehicles (LEV) are closely related with sustainable consumption within the personal mobility this paper focuses on consumer segmentation of potential LEV buyers and their willingness to buy LEV. Results have revealed that the segment of potential alternative fuel vehicles buyers is much larger than we initially anticipated. Such vehicles are, surprisingly, also more attractive for the older population, according to our results.

Opis:
Billions of people in the world are at risk of getting unsafe food. There is an urgent need to improve efficiency and effectiveness of food supply chains. The global population is expected to reach at least 9 billion by the year 2050, requiring up to 70% more food than nowadays and demanding food production and distribution to become much more sustainable. Today, food safety is a worldwide concern due to a number of food safety scandals. As supply chains become more globalized and complex, the ability to track and trace products from fork to farm becomes more difficult but remains equally important. Good traceability may minimize the production and distribution of unsafe or poor quality products. It allows targeting the product affected by a food safety problem, minimizing disruption to trade and any potential public health risks. The objective of this paper is therefore to conduct a comprehensive analysis of traceability methods and technologies in food supply chains.
