    A major drawback in the present industrial system is that the industries are directly discharging industrial effluent to nearest waterbodies in a linear way. Even though, a few of industries have considered reusing treated and untreated wastewater in their industrial premises, it can be further extended towards ‘exchange’ among the multiple industries under the concept of Industrial Symbiosis (IS). Initiating IS-based treated wastewater exchange networks is a novel approach to Sri Lankan industries and there is a lack of a study on potentials and barriers of implementing the concept. Hence, this research aimed to investigate the potentials and barriers for exchanging treated wastewater among industries. In order to achieve the aim, 16 semi-structed interviews were conducted with industry experts in the field of Industrial Water Management (IWM) to collect the data. Code-based content analysis technique was used to analyse the data by applying QSR NVivo.12 software. Findings revealed geographical proximity of industries, willingness of industries to engage in water exchange and industry level water management initiatives as major potentials for initiating water exchange networks. Lack of expected water quality for industrial needs, outdated technologies used in water management and lack of expertise and awareness were identified as major barriers. Accordingly, strategies, such as introducing national policy enhancements, ensuring cultural adaptation, enhancing technology & infrastructure, and empowering research & development, were proposed to overcome the identified barriers to ensure a successful implementation of treated wastewater exchange networks targeting the socioeconomic development of the country

    Drivers and barriers to implement green building practices in higher education institutes in Sri Lanka
    (Ceylon Institute of Builders - Sri Lanka, 2022-06-24) Illeperuma, IE; Abeynayake, MDTE; Sandanayake, YG; Waidyasekara, KGAS; Gunatilake, S
    Higher education institutes have a vast variety of humans, processes, and activities with significant waste generation, transportation, water and material consumption, and energy and electricity consumption. They have the potential to disseminate and lead future generations in the transition towards sustainability. Green buildings are designed, constructed, and operated by efficiently utilizing resources to provide a healthy and comfortable built environment while minimizing the life cycle cost. Higher education institutes across the world are several steps ahead of Sri Lanka in implementing green building practices. Thus, this research aimed to find approaches to increase the implementation of green building practices in higher education institutes in Sri Lanka. The research aim was approached through a qualitative case study. Accordingly, three cases were studied by collecting data through nine semi-structured interviews. Collected data were coded by using the NVivo 11 software and analysed using the cross-case analysis. Findings revealed that benefits associated with green buildings, leadership, specialization of the institute, institutional policy, and imposed regulations drive Sri Lankan higher education institutes to implement the green building practices. Lack of awareness, professional knowledge, skilled labour, and funds, political regime changes, poor planning, and stakeholder management were identified as barriers. The research outcomes guide the policymakers and management of the Sri Lankan higher education institutes to effectively implement green building practices. Further, the research outcomes will help to make strategies to reinforce the drivers and mitigate the barriers.
