Oct 13, 2025 by leolavanderia.com.br 126 views

Introduction

In recent years, the world has been facing a significant challenge in managing waste, particularly in the industrial sector. The increasing amount of waste generated by industries has not only caused environmental pollution but also wasted valuable resources. One of the most significant contributors to waste generation is the cement industry, which produces a substantial amount of waste in the form of cement kiln dust, also known as slack. Slack is a by-product of the cement manufacturing process and is typically disposed of in landfills or used as a filler material in construction projects.

However, a team of researchers from PDAM Tirtanadi, a drinking water company in Medan, has successfully utilized slack waste from the Cemara stool mud processing installation to produce environmentally friendly charcoal briquettes. This innovative approach not only reduces waste volume but also provides an alternative energy source that is environmentally friendly and sustainable.

The Process of Making Briquettes

The process of making briquettes involves mixing slack charcoal that has been mashed with polyacrylamide adhesive. The mixture is then printed into a cylinder shape with a pressure of 85 and 105 kg/cm2. The drying process is carried out in an oven at a temperature of 150 ° C for 1.5 and 2 hours. The researchers experimented with different ratios of materials, including adhesive, to determine the optimal mixture for producing high-quality briquettes.

The results of the experiment showed that the best briquettes were produced with a raw material ratio of adhesive 5:2, pressure of 105 kg/cm2, and drying time of 120 minutes. This briquette has a heat value of 7436.55 cal/g, water content of 7.277%, density of 1.06 g/cm3, and combustion time of 613 seconds. The characteristics of this briquette meet the SNI 01-6235-2000 standards for heat and water content, as well as American standards for density.

Economic Analysis

The economic analysis of the business of making stool briquettes with a capacity of 300 kg/day shows that it is a viable and profitable venture. The estimated profit of Rp. 547,029,828/year, Net Present Value (NPV) value of Rp. 203,510,791, Internal Rate of Return (IRR) 21.59%, and Break Event Point (BEP) 26.08% indicate that the business can generate significant revenue and returns on investment.

The capital required to set up the business can be recovered in around 11.34 months with sales of 24.41 tons of briquettes and income of Rp. 183,075,000. This makes the business an attractive option for investors and entrepreneurs looking to invest in a sustainable and environmentally friendly industry.

Advantages of Utilizing Slack Waste

The utilization of slack waste into charcoal briquettes has several advantages. In addition to reducing waste volume, charcoal briquettes can be an alternative energy source that is environmentally friendly. The use of charcoal briquettes can also reduce dependence on fuel oil and support the greening program by reducing tree logging for fuel.

Furthermore, the production of charcoal briquettes from slack waste can create employment opportunities and stimulate local economic growth. The business can also contribute to the development of sustainable waste management practices and promote a culture of environmental responsibility.

Conclusion

The research on utilizing slack waste from the Cemara stool mud processing installation to produce environmentally friendly charcoal briquettes has opened up new opportunities for the development of wastewater treatment technology that is more environmentally friendly and sustainable. The innovative approach has shown that charcoal briquettes can be an alternative energy source that is not only environmentally friendly but also economically viable.

It is expected that similar innovations can be applied to various types of waste to improve resource efficiency and reduce negative impacts on the environment. The success of this research has paved the way for further research and development in the field of waste management and sustainable energy production.

Recommendations
