“…The term biofuel is as such referred to solid, liquid, or gaseous fuels that are produced from plant matter and residues, agricultural crops, municipal wastes, and agricultural and forestry by-products (Aburas and Demirbas, 2015a;Qin et al, 2009Qin et al, , 2010Altun and Yasar, 2013). Liquid biofuels can be used as an alternative to traditional fossil fuels in the transportation sector (Aburas, 2015).…”

Biodiesel is an alternative to petroleum-based fuels derived from a variety of feedstocks, including vegetable oils, animal fats, and waste cooking oil. At present, biodiesel is mainly produced from conventionally grown edible oils such as soybean, rapeseed, sunflower, and palm. The cost of biodiesel is the main obstacle to commercialization of the product. Biodiesel produced from edible oils is currently not economically feasible. On the other hand, extensive use of edible oils for biodiesel production may lead to food crisis. These problems can be solved by using lowcost feedstocks such as non-edible oils and waste cooking oils for biodiesel production. This paper reviews numerous options of non-edible oils as the substantial feedstocks, biodiesel processing, and effect of different parameters on production of biodiesel.

“…Even though coal reserves are abundant, nearly half of the world's total coal deposits are low rank coals [2]. In Turkey, about 43% of fossil fuel production is lignite [1]. Meanwhile, low rank coals are very abundant in Australia, Central Europe and Eastern Europe, the northern US, Germany, Japan and China [3][4][5][6].…”

“…Especially in China, about 70% of electricity is from the burning of coal. The known coal reserves in the world are enough for more than 215 years of consumption, which is much more than both known gas reserves and oil reserves [1]. It is predicted that coal will still play the most important role in the energy supply until 2050.…”

“…This group includes coal waste (waste of flotation and gravity enrichment, various slimes), as well as waste of oil origin (for example, waste oil, water-oil emulsion, oil sludge). Their conversion, processing for the purpose of repeated targeted use is possible, but very costly [1,2]. The amount of waste is constantly growing.…”

“…Today, the problems of co-combustion of coal and biomass are being intensively studied [7,8]. There is also the experience of burning a coal granulate obtained after the addition of oil sludge, oil refinery waste, used industrial and household oils [1,9]. The novelty of this paper is that for the first time, we will analyze both energy and environmental parameters of ignition and burning of coal processing waste, used petroleum oil and vegetable oil during combustion in the form of a granulate, a droplet of slurry and jelly-like particle.…”

A lot of industrial waste is generated annually throughout the world. The extractive and processing industries are traditional leaders in the field of waste generation. According to the minimum estimates, several hundred million tons of coal processing and refining wastes are generated every year in the world. More than 2 billion tons of these wastes have already been accumulated. An important global goal is the effective, large-scale and safe recycling of industrial wastes. One of the ways to achieve this goal is to develop useful technologies of combustion of industrial wastes as composite fuels. Fuels prepared on the basis of coal processing waste, rapeseed oil, used turbine oil were considered in this study. We tested three forms of waste derived fuels: slurry, dried slurry (after storage) and granulate. Energy, environmental, economic aspects of the use of these fuels were under study. We determined the time and temperature parameters of ignition and combustion of the tested fuels using a laboratory muffle furnace (at 350-1000 °C). The concentrations of dangerous sulphur and nitrogen oxides, contained in combustion products, were also measured. It was established that the granulated fuels have minimum ignition temperatures and ignition delay times (50-80% lower than for the slurry and dried slurry). However, the combustion of waste derived slurries is characterized by minimum concentrations of NOx and SOx (by 18-75% lower than in the granulated state). Taking into account the cost, we calculated the efficiency of the tested fuels in comparison with traditional coal. According to the integral relative parameters, the use of waste-derived slurries is most attractive. The results of the research can be used in the thermal engineering to develop efficient (by energy, environmental and economic parameters) heat and power generation technologies by combustion of composite fuels derived from industrial waste.
