ABSTRACT
This study was carried out to examine green workplace initiatives and employee productivity in manufacturing firms using Delta Steel Company, Delta State as a case study. The study was specifically carried out to examine the effect of green workplace design on employee productivity in manufacturing firms, assess the influence of energy efficiency practices on employee productivity in manufacturing firms, examine the effect of green awareness on employee productivity in manufacturing firms and evaluate the impact of waste reusability practices on employee productivity in manufacturing firms. The study employed the survey descriptive research design. Hence, the questionnaire was used for data collection, while the data collected were analyzed using frequency tables, mean scores and standard deviation. The hypotheses test was conducted using Simple Linear Regression statistical tool. The population of the study consists of 320 employees of Delta Steel Company, Delta State, while a sample size of 175 was determined using Krejcie and Morgan table, out of which 163 questionnaires were found valid and used for analysis, and the sampling technique adopted was multi stage involving stratified and convenience sampling. The participants consists of both managerial and non managerial staff of Delta Steel Company, Delta State. From the responses obtained and analyzed, the findings reveals that green workplace design has a significant effect on employee productivity at β = 0.513, R² = 0.263, P = 0.001. The study also shows that energy efficiency practices have a significant influence on employee productivity at β = 0.487, R² = 0.237, P = 0.002. Likewise, the findings further revealed that green awareness has a significant effect on employee productivity at β = 0.462, R² = 0.213, P = 0.003, while waste reusability practices also have a significant impact on employee productivity at β = 0.478, R² = 0.229, P = 0.002. The study therefore recommends that manufacturing firms should strengthen green workplace design, promote energy efficiency practices, enhance green awareness programmes and improve waste reusability practices in order to improve employee productivity and organizational sustainability.

INTRODUCTION (Preview)
1.1 Background to the Study
Green workplace initiatives have become a strategic response to escalating environmental pressures and tightening stakeholder expectations, particularly in resource intensive manufacturing contexts, because firms are increasingly evaluated not only by what they produce but also by how they produce it (Adewumi, 2024). Moreover, there is now pressure from regulators, host communities, investors, and customers to provide clearer evidence of responsible resource use, reduced emissions, and safer operational practices, which requires manufacturing organizations to make sustainability a part of everyday routines rather than a project that is peripheral to regular work (Padilla-Lozano and Collazzo, 2021). Consequently, initiatives, including environmental training, process redesign, energy management and structured waste recovery, are implemented to limit ecological footprints and boost compliance and reputation (Muisyo & Qin, 2021). In addition, the increasing price of energy, materials and waste disposal has made the practices of green economics attractive economically, as improvements in efficiency can mean less operating costs and better competitiveness.
As part of the green workplace initiatives, green design focuses on the conscious use of environmental considerations in facilities, processes, and the layout of work flows. In manufacturing firms, this means eco conscious production planning, safer material substitution, low emission equipment choices and ergonomically aligned workstations to reduce strain and wastage (Padilla-Lozano and Collazzo, 2021). Furthermore, green design goes as far as to ventilation, lighting and space utilization to ensure that production environments are conducive to both ecological performance and operational stability (Adigun, 2025). As a result, well designed systems can reduce rework, reduce defect rate and simplify the flow of inputs and outputs, which in turn reduces unnecessary consumption of materials. Similarly, firms may follow design for environment principles such as modularity and ease of maintenance so that repairs are made more quickly and assets have longer life cycles (Jimoh, 2025). Hence, green design is not only a technical choice, but also managerial approach that incorporates sustainability in the core production logic.
Beyond green design, green awareness is also an important part of green initiatives. It refers to the degree to which employees are knowledgeable about the effects on the environment, understand eco friendly work practice and internalise organisational sustainability objectives in day to day decisions (Adewumi, 2024). Moreover, awareness is enhanced through trainings, signages, leadership communication, and peer influence that collectively form the norms that dictate behavior at the shop floor and in administrative units (Muisyo & Qin, 2021). Consequently when workers are able to identify energy leaks, excessive use of materials and avoidable emissions, they are more able to act responsibly and consistently. In addition, green awareness promotes the accountability of everyone, as staff members can monitor routines and encourage compliance without resorting to enforcement mechanisms only (Rufai and Mohammed, 2025). Therefore, awareness is often considered the basis for driving other green initiatives to work effectively in manufacturing firms.
Additionally, energy efficiencies are a large component of green workplace initiatives because the energy demand in manufacturing has a direct correlation with operating costs and carbon intensity. Energy efficiency practices such as preventive maintenance, motor and boiler optimization, insulation improvements, efficient lighting, compressed air management and real time monitoring of consumption patterns (Muisyo and Qin, 2021). Consequently, these interventions lead to reduction in downtime caused by overheating of equipment, unstable power supply and frequent breakdowns, thus stabilizing production schedules. Moreover, when energy management systems are implemented by firms, they can set targets, identify high consumption activities and institutionalize accountability across departments (Kajang et al., 2025). Likewise, efficiency initiatives tend to have behavioral aspects such as turning off idle machines and using energy only when needed, which relates back to employee awareness and supervision. Therefore, energy efficiencies work as a technical and human centered initiative which can enhance reliability and performance.
Similarly, waste reusability aims at reducing the amount of materials directed to disposal by reusing, recycling and recovering value from production byproducts. In the manufacturing process, this could include segregation at the source, repurposing of scrap, reuse of packaging, water recovery and creating closed loop material flows with suppliers and customers (Garba and Ike, 2025). Moreover, waste reusability implies clear procedures, easy collection points and quality controls to guarantee that recovered materials meet standards for reintegration into production (Padilla-Lozano and Collazzo 2021). As a result, firms can reduce procurement costs, clutter of work areas, and improve housekeeping, which affects safety and orderliness. In the same vein, reuse practices often lead to process learning as teams investigate where waste is coming from and redesigning tasks to ensure that it does not happen again (Adigun, 2025). Thus, reusability of waste is the nexus of operational discipline and environmental stewardship that also supports the culture of continuous improvement. The above-mentioned variables are predicted to have significant impact on the performance of employees in Manufacturing sector.
Consequently, employee productivity in manufacturing companies is usually measured in terms of output per worker, quality consistency, speed of task completion, stability of attendance, and the capability to achieve production goals with very little errors (Adewumi, 2024). Furthermore, productivity encompasses both efficiency and effectiveness as producing more units without meeting specifications may result in more rework and lower performance results (Muisyo & Qin, 2021). Apparently, modern discussions on productivity also take into consideration safety compliance, teamwork, and problem solving because these factors maintain a long-term throughput and ensure protection of organizational assets (Kajang et al., 2025). In addition, employee productivity is influenced by working conditions, employee skills, technology, motivation, and organizational support systems, which interact on a daily basis in the manufacturing environment.
The correlation between green workplace programs and employee productivity is being more and more put forward as reinforcing and not competing priorities. For example, green awareness can be used to improve compliance with standard operating procedures, lessen careless handling of materials, and increase attention to detail, which will improve the quality of output and reduce time losses due to avoidable errors (Muisyo and Qin, 2021). Moreover, green design can help to support productivity through creating more fluid workflows, reduced congestion, and improved ergonomic comfort to reduce fatigue and support sustained performance throughout shifts (Padilla-Lozano and Collazzo, 2021). Therefore, in case energy efficiencies stabilize equipment operation and minimize unexpected downtimes, employees will have less waiting time to have machines back on track and more time to manufacture to plan (Kajang et al., 2025). Likewise, waste reusability initiatives can lead to tidy workspaces and disciplined material management that can reduce search time and accidents that interrupt production.
Regarding behavior, green initiatives can increase employee engagement because it is an indicator that the management cares about responsible practices and safer environments, which can increase commitment and discretionary effort (Jimoh, 2025). In addition, training relating to green awareness often develops broader competencies such as problem identification, data recording and teamwork, which translate into increased productivity on the shop floor (Rufai and Mohammed, 2025). From a systems perspective, green design and energy efficiencies help to minimize process variability which, in turn, helps to minimize defect rates and supports consistent cycle times, which helps to improve individual and group productivity (Padilla-Lozano and Collazzo, 2021). Similarly, reusability of waste can be used to stimulate continuous improvement routines in which workers monitor waste sources and redesign work tasks to create learning loops to improve performance (Adewumi, 2024). Therefore, productivity improvements can be achieved by enhanced motivation, fewer disruptions and more productive processes working together.
In this regard, the manufacturing companies in Nigeria have a unique combination of issues including high energy prices, infrastructural constraints, and mounting demands to be sustainable. Consequently, adopting green workplace initiatives may be a necessity and an opportunity for firms that are aiming at resilience and competitiveness (Garba & Ike, 2025). Moreover, the manufacturing sector is often a sector that operates with heavy machinery, material intensive processes and significant waste streams, which means that green design, energy efficiencies and waste reusability are particularly relevant for performance improvements (Adigun, 2025). In addition, raising green awareness among the employees can contribute to the implementation of sustainability policies into day-to-day routines, particularly where informal work practices may dominate and need to be structured and changed (Muisyo & Qin, 2021). Thus, research on the correlation between green programs and employee performance will be critical in determining how environmental accountability can be in harmony with, and even fuel operational efficiency in the industrial contexts.

1.2 Statement of the Problem
The growing use of green design, energy efficiencies, green awareness and waste reusability initiatives in manufacturing companies is indicative of the growing understanding that environmental sustainability can impact organisational outcomes, especially employee productivity. Green design has especially been linked with better working conditions and increased task efficiency. Similarly, energy efficiencies such as the use of energy-saving machinery and optimized production systems are expected to decrease operational strain and create more supportive work environments. Further, Jimoh, (2025) green awareness programmes which aimed at enhancing the understanding of employees regarding their environmental responsibilities could also influence motivation, engagement and output. Moreover, energy efficiencies and waste reusability programmes, in particular, are often designed with operational cost savings in mind, but their effect on employee productivity has not been fully investigated. Padilla-Lozano and Collazzo (2021) claim that the productivity of employees is not only determined by managerial practices, but also by the environmental context in which work is performed. In the case of manufacturing companies, the adoption of energy-saving practices, green design layouts, and organized waste management systems can have an effect on employee performance for the better, by providing a good and efficient work environment, or for the worse, if not integrated into the daily functioning of the operations.
In the current business environment in Nigeria, manufacturing companies are increasingly experiencing pressures to incorporate environmentally sustainable practices such as green design, energy efficiencies, green awareness and waste reusability in their day-to-day activities while ensuring high workforce performance (Muisyo and Qin 2021). However, a link between these green initiatives and measurable improvements in employee output is not well-established. Aparrently, many firms in Delta State have introduced environmental programmes, but the level at which the programmes have transformed into productivity gains is not clear, leaving a critical knowledge gap about linking sustainability and workforce efficiency. Thus, the existing literature does not provide evidence on the interaction and enhancement of workforce productivity by the above-mentioned initiatives.
The lack of localized empirical studies also makes it more difficult for managers to make decisions on green workplace initiatives. Based on observation, much of the available research is based on developed economies or multinational corporations, there is a gap in understanding the dynamics of green initiatives in emerging contexts such as Delta State. Consequently, manufacturing firms in the region tend to incorporate green design, energy efficiency, waste reusability and awareness programmes without clear evidence of their contribution to productivity. Kajang et al. (2025) suggest that measuring the direct impact of these initiatives on employee output is important in bridging the gap between environmental goals and workforce performance. This study aims to fill this gap by systematically examining the effects of green design, energy efficiencies, green awareness, and waste reusability on employee productivity in manufacturing companies.
