The Impact

Cement production is an energy-intensive process. Utilisation of fossil fuels is common practice in the cement industry around the world. Alternative fuel substitution rates increase every year. More specifically, 18 % of the fuel used by the European cement industry in 2006 consists of alternative fuels. This study aims to investigate the prospects for the partial replacement of conventional fossil fuels currently used in the TITAN cement factory in Thessaloniki, Greece, with alternative fuels, focusing on the impact of alternative fuel use on the emissions of air pollutants from co-incineration operations. Air emissions were estimated for both the conventional fuel and mixtures of conventional fuel with alternative fuels, based on emission factors found in the literature but also using the measurements conducted by TITAN in 2010. Emission estimates indicate that legislative limit values for all pollutants are not exceeded. Based on the emission estimates and measurements in the flue gas, the dispersion of the plume around the factory has been described with an appropriate numerical simulation model. Results suggest that the factory’s contribution to the air pollution levels in the surrounding area is very low for most regulated pollutants.

As the capital city of Indonesia, Jakarta had a population of 10.2 million in 2015 that generated 6200 metric tonnes (Mt) day−1 of municipal waste in the 2017–2019 period. In the composition of the waste, as much as 9% is contributed by the commercial sector. This research focuses on five shopping areas in Jakarta (commercial areas (CAs)). The five CAs produce 110 Mt of waste per day and 79% of them are disposed of in landfills. 95% of the waste is a combustible fraction which can be used as an alternative fuel by the cement industry because the fraction has a low heating value of around 24 MJ kg−1. It is estimated that in one year, the CAs can produce about 34,500 Mt of alternative fuel with 820 TJ of energy. Approximately, the resulting energy savings are 2.6% which is equal to approximately 35,500 Mt of coal. In addition, the utilization of alternative fuel can reduce carbon dioxide emissions by 1.7% or 50,000 Mt.

Waste Printed circuit boards (PCBs) are one of the most valuable and recycled components of electronic waste due to the presence of precious metals such as copper, silver, gold and palladium. The rejects of the PCB recycling process, named non-metal fraction (NMF) have continuously been sent to landfills. Several researchers have proposed alternative use of NMF as secondary materials such as fillers in composites or as adsorbent. This study is focused on the potential application of the PCB recycling rejects as waste-derived fuel or alternative fuel in the cement industry. Approximately 2 million metric tonnes (Mt) of this waste was produced in 2014 globally and estimated to reach 6.5 million Mt in 2050. The presence of high organic matter in the NMF renders it useful as an alternative fuel. The organic content of the NMF could also potentially be increased using gravity separation and thus increasing its net calorific value. The study showed that the NMF could provide up to 21 MJ kg-1 of heating value with low heavy metal and ash concentration. A comparison with other waste-derived fuel sources is also presented in the paper.
