Abstract

PT. X is a pharmaceutical company that produces wastewater with the potential to harm the environment. Although the company already has a wastewater treatment system in place, this study evaluates its performance through direct field surveys and qualitative analysis based on ideal treatment standards. The treatment system at PT. X uses a series of five stabilization tanks operated in a continuous flow. However, BOD and COD test results from November 2019 to March 2020 show that the treated effluent does not meet the required pharmaceutical wastewater quality standards. This indicates the need to redesign the existing treatment system. One solution is to improve the biological treatment process, as the current BOD/COD ratio of around 0.5 suggests poor biodegradability. In addition, introducing an electrocoagulation process could enhance performance, with COD removal efficiency reaching up to 55.4%.

Abstract

The urgent environmental challenges posed by the high carbon footprint of ordinary Portland cement (OPC) demand sustainable alternatives in the construction industry. This study aims to evaluate the mechanical performance, durability, environmental impact, and economic feasibility of fly ash-based concrete as a partial replacement for OPC in Nigeria’s construction sector. Concrete mixtures with 20%, 40%, and 60% fly ash replacement were prepared and tested for compressive strength, workability, chloride penetration resistance, sulfate resistance, and water absorption. Advanced life cycle assessment (LCA) and economic analyses were conducted to quantify environmental benefits and cost savings. Results indicate that early-stage compressive strength decreases with increasing fly ash content due to slower pozzolanic reactions; however, significant strength gains occur at later curing stages, with 90-day compressive strengths reaching up to 42 MPa for 40% fly ash mixtures. Durability improvements were demonstrated by a 50% reduction in chloride permeability and a decrease in sulfate-induced mass loss from 0.7% to 0.2% at 60% fly ash replacement. The LCA revealed a reduction in CO₂ emissions by up to 51%, while economic analysis showed cost savings of up to 20% compared to conventional OPC concrete. These findings confirm that fly ash-based concrete provide enhanced durability and substantial environmental and financial advantages, making it a viable, sustainable alternative for construction in Nigeria. However, challenges such as supply chain constraints, quality control, and limited industry awareness must be addressed to enable widespread adoption. Future research should focus on improving fly ash reactivity, exploring hybrid supplementary cementitious materials, and conducting long-term field performance studies to further optimize and validate fly ash concrete applications under local climatic conditions.

Abstract

This research explores the role of technology and innovation management in facilitating the adoption of Circular Economy (CE) principles within Nigeria’s renewable energy sector. As Nigeria strives to address its energy deficit through renewable energy technologies, the integration of CE practices remains limited, especially in terms of resource efficiency, waste reduction, and material recycling. Using a mixed-methods approach, including semi-structured interviews with key stakeholders and a survey of renewable energy firms, this study assesses the extent of technology adoption and Circular Economy integration. The results indicate that solar photovoltaics (PV) and biomass are the most widely adopted technologies, with 80% of firms using solar PV. However, advanced Circular Economy practices, such as waste-to-energy and material regeneration, have been adopted by only 40% of firms. The research identifies several key barriers to the adoption of Circular Economy practices, including technological limitations, high initial costs, lack of government support, and low awareness. The findings underscore the pivotal role of innovation management in overcoming these barriers, particularly through the adoption of advanced technologies like solar PV and energy storage systems. The study concludes by offering policy recommendations, including the need for financial incentives, investment in research and development, and fostering collaborative innovation. These measures are essential for accelerating the adoption of Circular Economy principles, ensuring the sustainability and growth of Nigeria’s renewable energy sector.
