This study, investigates the energy efficiency potential of a cement production process based on the operational control approach, which has been developed. In this context, indicators that concern consumption of specific energy users were defined and limit values were determined. Accordingly, energy efficiency potential was found to be 3.5% depending on the control of 122 operational parameters. When the consumption loads of the enterprise are taken into account, the annual savings potential was found to be 4.5 GWh/year of heat energy and 39 GWh/year of electricity. These processes indicated a total of 10,334.99 tons of CO2 per year. At the end of the study, the contribution of the developed approach to the energy management processes was evaluated. In this respect, in cement production, mill inlet temperatures, secondary temperature, and main drive power emerge as the main operational indicators for energy efficiency for raw mills, rotary kiln, and cement mills, respectively.

Feasibility of hydrochar and activated carbon production from brewed tea waste was investigated in this study. Brewed tea waste was hydrothermally carbonised in subcritical water to obtain hydrochar as energy feedstock. Hydrothermal carbonisation experiments were performed at different process temperatures to determine its effect on fuel properties and combustion behaviour of resultant hydrochar. Increasing the process temperature yielded less amount of hydrochar. Higher calorific value and lower burnout temperature was observed for hydrochar. Hydrothermal carbonisation could remove only 25%-35% of initial ash in biomass and could not remove CaO in brewed tea waste. Hence, hydrochar had high slagging risk during combustion, which was only slightly lower than that of feedstock. On the other hand, hydrochar had lower fouling risk due to removal of K2O. ZnCl2 activation of hydrochar produced an activated carbon with high surface area and acceptable porosity.
