Research into modern methods of producing energy-efficient building materials

Abstract

The study is devoted to the analysis of modern methods of production of energy-efficient building materials. A broad review of statistics on the level of emissions of harmful substances and the popularity of various energy-efficient materials was carried out, which made it possible to identify the environmental factor as the most vulnerable. Analysing the United Nations (UN) recommended measures to reduce CO2 emissions from the production of building materials and the amount of CO2 emissions in different countries, cement, steel and aluminium add 2.5 billion tonnes of CO2. In comparison, brick and glass production adds approximately 1.2 billion tonnes of CO2 annually. The problem of producing materials more adapted to regional peculiarities, such as insulation made from local natural materials, is considered in the example of Kyrgyzstan. Modern methods of building materials production in Ukraine include, for example, improving the quality of cement, the use of green energy and the production of Portland cement clinker. The use of waste in construction is an important step towards sustainability and environmental efficiency. This is especially true for ergonomic construction, where waste management reduces the negative impact on the environment and reduces natural resource consumption. Despite advances in construction technology and the introduction of alternative materials, bricks remain one of the most common materials. India is a leader in this area, although a study of its statistics revealed that due to the global prevalence of informal production practices, accurate statistics are difficult to collect. All sub-sectors of the ceramic industry are energy-intensive due to the need for drying and sintering at high temperatures (800-2000°C), which requires significant energy resources. Sustainability-oriented solutions and technology substitution are proving to be key to the decarbonisation of the ceramic industry. The combination of different technologies and approaches provides significant benefits in reducing CO2 emissions and energy consumption. The study results are relevant for the development of recommendations for the integration of environmentally friendly, innovative and ergonomic methods of production of energy-efficient building materials.
