“…Moreover, numerous useful macro-and micronutrients, such as Ca, Mg, Fe, and Zn, were observed to positively correlate with the increase in temperature. Akyürek [13] carried out the pyrolysis tests performed at 10, 30, and 50 • C•min −1 heating rate from room temperature to 1000 • C under a nitrogen environment with a flow of 100 cm 3 •min −1 . Kinetics of decomposition were analyzed using the Flynn-Wall-Ozawa (FWO) method.…”

In the process of petroleum exploitation, the annual production of oily sludge in China’s petroleum exploitation industry alone has exceeded one million tons, which causes great harm to the environment. In order to face this problem, a variety of treatment methods have been sprung out, but the most of them are polluting the local soil and groundwater eco-environment. Pyrolysis technology for sludge treatment has several advantages, which have already made it a mainstream approach attracting worldwide attention. In this work, oily sludge from Yanshan Petrochemical Company was processed at the newly developed industrial-scale reactor. The sludge transportation in the whole system was achieved by the use of chain plate conveying, which has the advantages of preventing coking, effective sealing of sludge inlet and outlet, etc. First, lab-scale experiments were carried out at temperatures between 450 °C and 600 °C to obtain the best reaction conditions in the industrial-scale equipment. It was found that the maximum pyrolysis oil yield of 17.1 wt.% was obtained at 500 °C. The properties of oily sludge and related compositional characterization of the products (permanent gas, pyrolysis oil, and pyrolysis char) after the treatment were comprehensively analyzed. The study showed that the oily sludge in the reactor was completely converted, and resource utilization of the feedstock could be realized.

“…However, biochar can lock high portion of the carbon content of raw biomass in stabilized form in long term and hence contribute carbon-negative economy [16,17]. Biochar production has also considered as a potential waste management strategy for reducing the waste volume and elimination of pathogens especially for livestock manure [18]. In addition, heavy metal content of the biomass feedstock remains within biochar [10].…”

Global climate change driven by anthropogenic activities have diverted the attention on the development of the methods for atmospheric carbon dioxide capturing and sequestration, the so called negative emission technologies (NETs). Pyrolysis is one of the most environmentally friendly conversion technologies for waste disposal that are being developed to convert waste materials into energy and valuable products. Biochar is high carbon content pyrogenic solid material obtained by thermal degradation of biomass in an oxygen-free medium. High nutrients content in biochar makes it a suitable material for soil amendment purposes. Furthermore, biochar acts as a carbon sink to reduce atmospheric greenhouse gas (GHG) emissions thus can play a significant role in the control of environmental pollutants by carbon negative emissions. In this study, the carbon dioxide sequestration potential assessment of a wide range of biomass including agricultural residues, forestry residues, livestock manure and municipal solid waste (MSW) in Turkey have carried out. The results revealed that pyrogenic carbon bio-sequestration in Turkey is possible with negative emissions potential of biomass is 60.38 Mton CO2eq/year, which accounts for 16 % of the total annual carbon dioxide emission. Biochar is an untapped resource for emission abatement strategies.

“…Among the renewables, biomass is the only energy source which can deliver electricity, provide heating, cooling and used as fuel in solid, liquid and gaseous forms [1]. Biomass has attracted more attention in recent years as a low risk and capital required renewable energy source [2][3][4][5]. Biomass refers to carbonaceous materials derived from agricultural crops, forestry, agro-industrial and domestic wastes.…”

Sustainable development depends on the availability of energy resources and their impact on environment. Biogas is a carbon neutral renewable energy option and one of the leading solutions to the climate change combat. As Turkey is an energy importer country, using indigenous energy sources is vital to meet future energy demand. Agricultural activities and livestock potential have high contribution to economy in Turkey. Biogas production from organic wastes such as livestock manure in this context, gain more importance to contribute both renewable energy production and waste management strategies. Livestock farming has important economic value in Burdur. In this regard, the animal manure based biogas potential, energy value, electricity and organic fertilizer generation capacity of Burdur Province were determined in this study. The results revealed that Burdur has annually 1.45 million tons of available animal manure potential to be used for biogas production of 27.1 million m 3 /year. This potential corresponds to 135.4 GWh annual energy generation that could be converted to heat and electricity. Considerable amount of the biogas production capacity has accumulated in the Center and, Bucak, Yeşilova, Gölhisar and Karamanlı districts of Burdur. In addition, about 50776 tons/year of organic fertilizer can be produced as the residual of the biogas plants.
