Turkey, being one of the largest producers of world cotton production, utilizes biomass through direct incineration for electricity generation which accounts for 1.5% of the total electricity generation in Turkey. In this work, biogas potential of cotton stalks was assessed to present a foresight to the future biomass valorizations in the country. Cotton stalks harvested in six cities located in the Southeastern, Aegean and Çukurova regions of Turkey were evaluated and discussed with respect to their potential in electricity generation and the invoiced electricity consumption in 2019. These cities were found to yield 15.6 million tonnes of cotton stalks with an annual 3.1 billion m3 of methane and also, 12 TWh of electricity generation that could meet almost 32% of the electricity demand. For Southeastern region, region’s electricity consumption could be met by 99.5% with the anaerobic digestion of cotton stalks (9 million tonnes/yr). Methane potentials of cotton stalks were compared with the corresponding syngas yields and lower percentages were obtained for syngas. Anaerobic digestion and thermochemical conversion of agricultural residues, being proposed as energy strategies in this study, could help to accelerate the activities on bioenergy share in Turkey.

“…It was also revealed that the province of Mersin has the biggest biogas potential. Senol and Zenk investigated the electrical energy potential of hazelnut shells for various provinces in Turkey 37 . The electrical energy potential calculated for each city was compared with the electricity consumption used in those cities.…”

Summary Biomass energy sources consist of materials such as wood obtained from forests, wastes from agriculture and forestry processes, and industrial, human, and animal wastes. Biogas energy is generated as a result of the anaerobic decomposition of biomass. The analysis of biogas energy potential from animal waste plays a significant role in developing countries, which involves Turkey. Therefore, the work executed in this article presents a case study for such regions. A comprehensive analysis for the production potential of biogas from the wastes of breed animals in TR83 region in Turkey, which includes the provinces of Amasya, Çorum, Samsun and Tokat is presented in this study. The number of animals and their total waste generation were determined. Then the biogas potential, along with the electricity production and the reduction of CO2 emissions, were calculated accordingly. In addition, the amount of biogas that can be produced in the TR83 region has been determined to be 151.8 M m3 per year from cattle, 6.3 M m3 per year from small cattle, and 12.9 M m3 per year from poultry. As a result, the optimal location for biogas plants based on supply chains were determined. Accordingly, the electricity potential that can be generated for the TR83 region has been determined as 49.25 MW. In addition, it has been found that approximately 19 times more carbon emissions will occur if electricity is obtained from natural gas, and approximately 34 times more emissions will be given off if it is obtained from imported coal. Ultimately, the resulting facility placement points were found to be Suluova, Çorum, Sungurlu, Bafra, Çarşamba, Vezirköprü, Erbaa, Tokat and Zile.

“…Hazelnut orchards are located in the northern latitudes at 36-41°, 30 km inland from the coastal regions, and in places not exceeding 0.75 -1 km in height. While in 33 cities, there are hazelnut-growing zones, only 16 are permitted for the processing of commercial hazelnuts (Şenol and Zenk, 2020). Turkey's annual hazelnut production is shown in Fig.…”

Time series forecasting methods are used by an evolving field of data analytics for the prediction of market trends, sales, and demands. Turkey is the major producer of hazelnut in the world. If Turkey wants to continue its domination of hazelnut and protect the price-setting role, time series forecasting methods could be key factors accordingly. There are a few studies that focused on time series forecasting of hazelnut export quantities of Turkey, and this study uses a recently developed algorithm and implements a power transformation to increase the forecast accuracy. The presented research aims to forecast Turkey’s hazelnut export quantities for the coming 36-months starting from June 2020. The forecasting process was conducted with the help of Facebook’s Prophet algorithm. To improve the forecast accuracy, a Box-Cox power transformation was also implemented to process. To find out the stationarity and periodicity of the data set, the Augmented Dickey-Fuller test and autocorrelation function was applied to the time-series data. The Prophet algorithm, with Box-Cox transformation, projected the hazelnut export quantity could be over five hundred thousand tons from 07/2020 to 06/2023. The export quantities were in an increment trend, and the slope of the trend has increased since June 2008 by 0.66 % per month. The Prophet algorithm also revealed the seasonality of the data set, and the export amounts indicate monthly oscillations. The monthly export volumes start to increase and reach their peak value in October because August is the time for the harvest of hazelnuts in Turkey.
