Based on the physical and chemical properties of carbide slag, the contents of heavy metals in effluent came from carbide slag drying process were studied, and then the composition of exhaust gas emitted from the carbide slag drying process and calcinations process of raw materials prepared with carbide slag was detected, in order to know whether there are harmful or corrosive gases released and the effect of the emissions on the environment and related equipments. The results indicate that the exhaust gases emitted from the calcination process of raw meal prepared with carbide slag is mainly composed of CO2 and water vapor, and is free from harmful gases. However, a lot of water in carbide slag during the pre-heat and decomposition process under high temperature would accelerate the corrosion of equipments. Simultaneously, a small number of heavy metal ions contained in the carbide slag can cause environmental pollution and sulfides would be adverse to the cement calcination process resulting in the crust blockage of kiln.

Anthropogenic lakes (lakes that have developed in mined-out pits as a consequence of mineral raw material mining) exhibit many interesting phenomena. Specific water features are the most remarkable, including physical, chemical and the biological characteristics. Other very specific morphometric feature of anthropogenic lake basins include the unusual location of the lake’s water surface: often several dozen meters below the adjacent terrain and the specific character of the mined-out raw materials. All of these factors affect the qualitative characteristics of lake’s water, even decades after flooding. The interaction of the factors mentioned above has resulted in the creation of a permanent meromixis in some anthropogenic lakes. The author’s primary objectives are to present some physical and chemical symptoms of meromixis at selected localities, to discuss the mutual interaction between the physical and chemical characteristics of lake water and to explore some probable causes of the origin of meromixis at the selected localities.

This article reviews various decontamination methods of herbal raw materials in Poland. These are the physical and chemical treatments of plant raw materials that remove mineral and microbiological impurities to ensure food safety. There is increasing use of herbal raw materials, and it is important to understand various methods that can be used for hygienization. Techniques used ensure the removal of mechanical impurities and elimination of microorganisms in a plant material. Depending on the method of choice, certain microorganisms are removed to a varying degree, and at the same time, there is a partial loss of the health-promoting properties of the plants subjected to the hygienization. Therefore, there is need to decide on optimal methods for hygienization of herbs that both reduce microbial contamination to the maximum extent and minimize the decrease in valuable ingredients contained in the herbs. Ozonization of plant raw materials is an effective method of removing microbiological contamination from most herbs. A good solution is also to use hybrid methods. In our literature review, ozone is very often mentioned as an effective disinfectant for herbs and spices. However, there is no information about the effect of ozone use on the substances contained in herbs and spices.

Постійний попит на сою і соєві продукти як на внутрішньому, так і зовнішньому ринках України зумовив розширення площі посівів під цією рослиною і вона стала одною з найприбутковіших культур, які вирощуються у сільськогосподарських підприємствах. Полінасичені жирні кислоти, які входять до складу  клітинних мембран сої та інших структурних елементів рослинних тканин, виконують в організмі низку важливих функцій, зокрема забезпечують нормальний ріст та обмін речовин, еластичність судин. У зв'язку з існуючою проблемою дефіциту білка в харчуванні людей все більшої актуальності набувають для України дослідження шляхів підвищення економічної ефективності виробництва сої, формування та функціонування ринку сої та продуктів її переробки.Тепловий вплив – одна з найбільш широко розповсюджених теплотехнологічних операцій в процесах обробки рослинної сировини, а тепловий нагрів з метою зменшення початкового вологовмісту сировини, що обробляється (сушіння) – один із найбільш розповсюджених способів консервування, підготовки і полуфабрикування харчових продуктів. На ряду з перевагами процесу сушіння виникає ряд недоліків процесу, найважливішим з яких, в сучасних умовах, є енерговитрати на виконання процесу. Процес сушіння - один з найбільш енергоємних операції, він використовує до 25% всієї промислової енергії. Через проблеми в екологічній і енергетичній галузях, включаючи викиди парникових газів, виснаження викопного палива тощо стає надзвичайно важливим  зменшення споживання енергії у всіх галузях промисловості.Створення рослинних композицій, поєднання двох сумісних за біохімічним складом матеріалів (сої та батату), дає можливість знизити енерговитрати на процес сушіння та зберегти біологічно активні речовини в процесі зберігання висушеної сировини. За своїм біохімічним складом батат містить каротиноїди, що є природніми стабілізаторами для білків сої і які перешкоджають окисленню її ліпідів. Отже, поєднання цих двох компонентів дозволяє природнім шляхом збільшити термін зберігання сировини. Через відсутність інформації в наукових інформаційних джерелах про вплив режимних параметрів сушіння (t, φ, υ) на кінетику сушіння соєво – бататної суміші, ця робота спрямована на дослідження процесу сушіння соєво - овочевих композицій з метою інтенсифікації процесу.    The constant demand for soy and soya products on both the domestic and foreign markets of Ukraine led to the expansion of the area under this plant and became one of the most profitable crops grown in agricultural enterprises. Polyunsaturated fatty acids, which are part of cellular soybean membranes and other structural elements of plant tissues, perform in the body a number of important functions, in particular, provide normal growth and metabolism, elasticity of blood vessels. Due to the existing problem of protein deficiency in people's nutrition, Ukraine is increasingly studying ways to increase the economic efficiency of soybean production, the formation and functioning of the soy market and its processing products.Thermal effect is one of the most widely used heat engineering operations in the process of processing of plant raw materials, and heat heating in order to reduce the initial moisture content of processed material (drying) - one of the most common methods of preservation, preparation and semi-preparation of food products. Along with the advantages of the drying process, there are a number of flaws in the process, the most important of which, in modern conditions, is energy costs for the process. The drying process is one of the most energy-intensive operations, it uses up to 25% of all industrial energy. Due to problems in the environmental and energy sectors, including greenhouse gas emissions, fossil fuel depletion, etc., it is becoming increasingly important to reduce energy consumption in all industries.The creation of plant compositions, a combination of two biochemical compositions (soybeans and sweet potatoes) compatible, makes it possible to reduce energy costs for the drying process and preserve biologically active substances during the storage of dried raw materials. In its biochemical composition, sweet potato contains carotenoids, which are natural stabilizers for soy proteins and prevent the oxidation of its lipids. Consequently, the combination of these two components can naturally increase the shelf life of raw materials. Due to the lack of information in scientific information sources on the influence of regime drying parameters (t, φ, υ) on the drying kinetics of soybean - vegetable mixture, this work is aimed at studying the process of drying soy and vegetable compositions in order to intensify the process.
