Sustainable processes and manufacturing have emerged as critical approaches for reducing environmental degradation associated with industrialization, urbanization, and construction activities across the world. Traditional manufacturing systems are heavily dependent on fossil fuels, intensive resource extraction, and linear production models that generate excessive waste, greenhouse gas emissions, and ecological destruction. Consequently, industries are increasingly adopting sustainable manufacturing processes that emphasize energy efficiency, waste reduction, recycling, cleaner production technologies, and circular economy principles. This study examines sustainable processes and manufacturing and evaluates their environmental impacts with particular focus on Nigeria and Jos metropolis in Plateau State. The study adopts an empirical research design involving questionnaires, interviews, field observations, and secondary data obtained from manufacturing firms, environmental agencies, and construction professionals. Findings reveal that sustainable manufacturing practices such as recycling, green supply chain management, closed-loop construction, renewable energy utilization, and low-carbon material production significantly reduce environmental pollution, conserve natural resources, and improve industrial efficiency. The study further reveals that industries adopting sustainable technologies experience reduced waste generation, lower carbon emissions, and improved environmental performance. However, challenges such as inadequate government policies, poor technical expertise, weak environmental enforcement, high implementation costs, and low public awareness continue to hinder effective adoption of sustainable manufacturing systems in Nigeria. The study concludes that sustainable processes and manufacturing provide viable pathways for achieving environmental sustainability, climate resilience, and resource conservation within Nigeria’s industrial and construction sectors. The paper recommends stronger environmental regulations, investment in green technologies, institutional support for sustainable industries, and public sensitization programs to enhance sustainable manufacturing practices across Nigeria.
