Capacity building for sustainable post disaster waste management: Construction \& demolition waste

Disasters, both natural and man-made, have been occurring with increasing frequency and effect in recent decades in many countries around the world. Among them, Sri Lanka is yet to recover from the effects of December 2004 Tsunami. Among many other reasons it has been identified that lack of awareness of the mechanisms and systems for post disaster waste management is a critical issue of concern. None of the Sri Lankan academic institutions related to the field offer courses designed for the management of disaster waste within the country. Furthermore, none of these institutions conduct awareness programmes aimed at the public on new mechanisms and systems of management of disaster waste. To address these issues, this research aims to enhance capacities to develop new mechanisms and systems for sustainable post disaster waste management focusing on construction and demolition waste. To achieve the identified aim, the research will explore current status of disaster waste management in Sri Lanka and a framework will be proposed for enhancing capacities for sustainable disaster waste management in economical, social and technological aspects. The research methodology includes a comprehensive literature review, semi structured interviews and case study with selected personal views on management of disaster waste management. In this context, the objective of this paper is to present the current scenario of disaster waste management based on the results of a secondary survey

Capacity building towards resilience: context of post disaster waste management

Capacity building provides an opportunity to understand strengths, weaknesses, threats and opportunities towards a resilient future through identification of broader issues around sustainable development of a particular program, project or process, including their unique cultural, social and ecological characteristics. Thus, concept of capacity building is an essential component in development theory and practice. In particular, in post disaster scenarios, focus has been placed upon local capacity building as a means of increasing resilience to natural hazards. In this context, this paper focuses on concept of capacity building and its role in post disaster waste management towards building future resilience. Case studies have been conducted to gather information on existing capacities of post disaster waste management in Sri Lanka. Semi-structured interviews were held as the main data collection method and content analysis was used to analyse collected data. Results of existing capacities and identified gaps of post disaster waste management are presented in key areas as skills and confidence building, links and collaborations, continuity and sustainability, research and development, communication and coordination, organisational implementations and investments in infrastructure. Finally, the paper concludes with proposed recommendations for enhancing capacities of post disaster waste management towards future resilience

Capacity building towards sustainability: Context of post disaster waste management

Concept of Capacity Building is an essential component in development theory and practice. In developing countries, it is identified as a key concept in achieving sustainability. In particular, in post disaster scenarios, focus has been placed upon local capacity building as a means of increasing resilience to natural hazards. In this context, this paper focuses on concept of capacity building and its role on achieving sustainable post disaster waste management. A literature review and pilot study have been conducted to gather information on post disaster waste management in Sri Lanka. Semi-structured interviews were held as the main data collection method and content analysis was used to analyse collected data. Unavailability of a centralized body, poor implementation of rules and regulations; lack of skills and confidence, inadequate funds, lack of communication and coordination were identified as prevailing capacity gaps in post disaster waste management. Thus, finally paper proposes a framework for capacity building for sustainable post disaster waste management

Waste management strategies during post disaster phase: A case of Sri Lanka

Natural or man made disasters cause serious negative impacts on life, property, livelihood and industries often resulting in permanent changes to societies and environments. In disasters, creation of waste due to damaged buildings and infrastructure is unavoidable. If these wastes are not properly managed, serious environmental and economic burdens will fall on general living conditions, reconstruction and as well as general waste collection processes. Therefore, management of disaster waste has emerged as a critical issue and poses a significant challenge to governing bodies in responding to a disaster. This is not unique to Sri Lanka which is prone to frequent natural disasters such as floods, landslides and droughts apart from the Asian Tsunami of 2004. This paper addresses post disaster waste management strategies adopted and issues and challenges encountered at both national and local levels in Sri Lanka during post - Indian Ocean Tsunami period. A comprehensive literature review and a field survey were conducted to gather information. Accordingly, most affected six districts were selected based on three types of disasters namely floods, landslide and the Tsunami. Seven national institutes responsible for managing disasters were selected for collection of data at national level. Semi-structured interviews were used as the main method of data collection at each stage and content analysis was used to analyze data that was collected. Local level findings revealed that strategies, issues and challenges vary according to the type of disaster, magnitude and location. Unavailability of a centralized body, poor implementation of rules and regulations; poor standards of local expertise and capacities, inadequate funds, lack of communication and coordination were identified as key issues at national level

Capacity Gaps in Post Disaster Waste Management: Case Study in Sri Lanka

Disaster waste is one of the major consequences aftermath of any disaster, impacts on public and environment, rescue and emergency services, provision of lifeline support and socio-economic recovery of affected areas. Thus, management of wastes created by disasters has become an increasingly important issue to be addressed in responding to a disaster. This chapter intends to present the prevailing gaps in disaster waste management and approaches to minimize the impacts on disaster management at developing countries with special emphasis to Sri Lankan context. Findings revealed that, unavailability of single point responsibility and provisions for disaster waste in existing policies and capacity constraints of the prevailing peace time solid waste management practices as major capacity gaps. Establishment of a regulatory body and enforceable rules and regulations with necessary levels of capacities were identified with seven areas for capacity building for post disaster waste management. The research enabled to attain sustainable post disaster waste management for future resilience

Impact of food, alcohol and pH on modified-release hydrocortisone developed to treat congenital adrenal hyperplasia.

BACKGROUND: We developed a modified-release hydrocortisone, Chronocort®, to replace the cortisol rhythm in patients with congenital adrenal hyperplasia. Food, alcohol and pH affect drug absorption and it is important to assess their impact when replicating a physiological rhythm. SUBJECTS AND METHODS: In vitro dissolution to study impact of alcohol and pH on Chronocort®. A Phase 1, three-period, cross over study in 18 volunteers to assess the impact of food on Chronocort® and to compare bioavailability to immediate-release hydrocortisone. RESULTS: In vitro dissolution of Chronocort® was not affected by gastrointestinal pH up to 6.0 nor by an alcohol content up to 20 % v/v. Food delayed and reduced the rate of absorption of Chronocort® as reflected by a longer Tmax (fed vs fasted: 6.75 hrs vs 4.5 hrs, p=0005) and lower Cmax (549.49 vs 708.46, nmol/L, ratio 77% with CI 71 - 85). Cortisol exposure was similar in fed and fasted state: Geo LSmean ratio (CI) AUC0 t for fed/fasted was 108.33% (102.30 - 114.72%). Cortisol exposure was higher for Chronocort® compared to immediate-release hydrocortisone: Geo LSmean ratios (CI) 118.83% (111.58 - 126.54%); however, derived free cortisol showed cortisol exposure CIs were within 80.0 125.0 %: Geo LSmean ratio (CI) for AUC0 t 112.73% (105.33 - 120.65%). CONCLUSIONS: Gastric pH ≤ 6.0 and alcohol do not effect hydrocortisone release from Chronocort®. Food delays Chronocort® absorption but cortisol exposure is similar in the fasted and fed state and exposure as assessed by free cortisol is similar between Chronocort® and immediate-release hydrocortisone

A comparison of municipal solid waste management in selected local authorities in Sri Lanka

Solid waste has become a critical issue with rising population, urbanization, economic activities and consumerism, especially in urban centers creating a negative impact on environment due to inappropriate handling of municipal solid waste. Further, social, economical and health issues such as unpleasant odor, ground water contamination, epidemics and social effects also are being created due to land filling. Lack of physical, human and financial resources, poor participation and less enthusiasm among community groups and government representatives overloaded with additional work none related to solid waste activities are significant challenges. Equally, literature revealed that existing SWM systems established within most local authorities are not properly operated and maintained in Sri Lanka. Hence, significant gaps are visible in solid waste management activities at local authorities. Thus, this research intends to explore municipal solid waste management systems in Sri Lanka to identify best practices. Case study research approach was used and multiple cases were selected representing both best and worst practices in municipal solid waste management. Data were gathered through semi structured interviews. An outcome of the study is a framework developed for best practices of solid waste management which can be used at local authorities for effective and efficient municipal solid waste management

Waste management strategeis: municipal waste vs Disaster waste

Waste has become a global issue with rising population, urbanization, economic activities and consumerism. Further, this is becoming more critical due to waste generated through frequent disasters. This is evident with increased number of environmental, social, economical and health issues such as epidemics. Thus, this paper intends to critically review waste management practices, of both municipal and disaster waste to identify prevailing gaps. Lack of physical, human and financial resources, less enthusiasm among community groups and legal loopholes are identified as major gaps. Community involvement in planning, development and implementation of waste strategies, enhancing strategic level capacities, raising public awareness and establishing supportive authorities are proposed to eliminate identified gaps

Industrial waste management: free trade zones in Sri Lanka

Industrial waste becomes a worldwide issue which was raise through the industrialization. Free trade zones are the one of major areas which is produced more industrial waste in Sri Lanka. Improper and isolation existing waste management practices in free trade zones create more environmental issues and spreading of deceases such as Dengue. Thus factories as well as zone management need proper system to handle the industrial waste. This study aims to explore the industrial waste management practices at Free Trade Zones in Sri Lanka in order to identify probable approaches to address the burning issues. Study was conducted through the case studies of three free trade zones which were generated highest industrial waste. Semi structured interviews were conducted with four participant of each case responsible for industrial waste management. In addition, two expert’s interviews were conducted to verify the case study findings. Findings revealed that, majority of people were not satisfied with existing isolation practices of industrial waste management due to various issues visible in existing industrial waste management process
