Zambian Construction is one of the fastest growing sectors (increasing at 15.3% pa in 2012) from residential and commercial developments and mining infrastructure. The industry in Zambia, like elsewhere, is composed of many players including designers, contractors, regulators, manufacturers and suppliers of construction materials. However, opportunities for sustainable construction waste minimization and management (WMM) have been minimal.Most research in developing countries has been targeted on Municipal Waste Management rather than Construction and Demolition (C&D) Waste. C&D Waste is generally in form of masonry units, mortar, timber, glass, steel and plastic and most generation is arises from masonry units and mortar. In the developed countries guidelines do exist, supported by regulation and legislation.This paper addresses the status on C&D waste management in Zambia as compared to the rest of the world, mainly through literature review, with a view to recommending strategies for sustainable Waste Minimization and Management. As highlighted by several researchers and institutions, worldwide, WMM requires partnerships of strategies, which covers processes over the entire life cycle of construction infrastructure. The paper highlights some of best practices towards sustainable C&D waste minimization and management elsewhere. Finally, recommendations are made on how to achieve best practice in Zambia, sub-region and beyond.Keywords: Municipal Waste, Construction and Demolition waste, design and construction practices

This article examines waste management and recycling as an element of reverse logistics in a circular economy. The concept of circular economy can be found very often in scientific and social environment. The aim of the article is to analyze the trends of waste management and recycling as a reverse logistics element in the conditions of circular economy in Europe and Lithuania. To achieve the goal were done: an analysis of theoretical sources to reveal the essence and connections of reverse logistics and circular economy, analysis of LR and EU legislation, development strategies of the environmental protection and waste management sector, analysis of EUROSTAT statistical data, monitoring, situation assessment and questionnaire survey. The main goals of the circular economy model are less raw materials, less waste, less emissions, managing such elements as raw materials, sustainable design, production, distribution, consumption, reuse, repair, collection, waste management, and residual waste. Direct logistics processes and reverse logistics play really important role in this concept. Logistics examines the movement of material, financial and information flows from the source of raw materials to the end user, reverse logistics examines the same flows, only in the opposite direction. Reuse, repair, collection, waste management are on responsibility of reverse logistics. For this reason, waste management in the terms of a circular economy cannot be seen only as the responsibility of the government and the end user (the resident sorting the waste). All participants in the supply chain, who were interested in bringing the material flow to the end user, and who created added value in the supply chain, according to the "polluter pays" principle, should take responsibility for the waste generated in the country, waste management and sorting, recycling. Because, for example, prevention of waste generation is a priority, and the cheapest solution is to avoid waste management and recycling. Thus, all participants in the supply chain must be interested and cooperate in the implementation of the circular economy. The general trends in the collection of the main sorted waste in Europe and Lithuania are not unambiguous, since waste management is regulated by different local laws of the countries. A general increase in the amount of sorted and collected waste is recorded, but not all countries demonstrate an increase, this may be related to the elements of the circular economy that have already been implemented, public awareness, declining consumerism, the economic situation in the country and other factors that lead to a generally more responsible approach to ecological aspects. EU newcomer countries are characterized by large increase in waste collection, regardless of waste types. Consumer opinion is quite favorable to the implementation of circular economy principles, but the main idea is that most of the responsibility for waste collection and management must be transferred to commercial participants in the supply chain.

Design academics struggle in effectively reaching out to design practice, while design practitioners have difficulties in appropriating academic output. In their turn, design practitioners create new local knowledge that may not be recognised (as such) by design academics. This situation is seen as suboptimal and problematised as the research-practice gap. This paper addresses how knowledge exchange between design research and practice can be understood and improved. We therefore introduce and investigate a social co-design case study which bridged the gap between research and practice and which shows how knowledge development within academia, professional design practice, and non-professional design practice are interwoven. We analyse the case through an alternative template analysis incorporating four perspectives on ‘the gap’: abstraction, communication, alignment of knowledge needs, supporting local knowledge production. We compare and interrelate these four perspectives. This refines our theoretical understanding of the research-practice gap and provides implications and actionable insights about practitioner-centred knowledge production for design academics who want to contribute to design practice.

Waste management is the need of an hour. It is one of the major concern for highly populated country like India. This paper looks at the challenges and practices of household waste collection and management in low-income urban areas, focusing on the central suburbs of Mumbai. Rapid urban growth, high population density, and poor infrastructure have made waste problems worse in these communities, where official municipal services often fall short. The study is empirical in nature. It aims to examine the various factors associated with the waste collection and management in Mumbai. The study explores waste sorting habits, how often waste is collected, the role of informal waste workers, and residents’ awareness of waste management rules. The findings show inconsistent service, low community involvement, and a strong dependence on informal collection networks. The study emphasizes the urgent need for inclusive, local, and community-led waste management approaches that consider economic challenges. Recommendations include raising public awareness, improving local governance, and formally including informal waste collectors. This paper offers practical ideas to improve sustainability and sanitation in underserved urban areas.

Besides application fields such as entertainment and marketing, the technology of Virtual Reality is also applied in research and practice, including domains such as automotive, architecture, and construction. Furthermore, VR has been utilized for several activities in design practice and design research. However, the impact of this technology on design as a profession remains to be investigated. Thus, in the present study, an integrative literature review is presented to investigate the potential impact of Virtual Reality on design research and design practice. The findings indicate potential advantages on different levels. VR has the potential to enhance problem identification due to laboratorial environments and to foster co-creation due to enhanced motivation and the establishment of synergies between the involved stakeholders. Furthermore, it supports prototyping activities due to its capabilities for realistic scaling and perspectives. And lastly, VR has proven to be advantageous for design evaluations and reviews due to its visualization and immersion potential. Drawbacks of using VR for design research and practice involve technical limitations such as restricted field of view, limited performance, but also aspects such as missing accuracy for prototyping and the absence of haptic feedback. Future work will involve an extended review involving further literature and application domains.

Material engagement in fashion and textile design practice using pattern cutting is an overlooked aspect of creative development in the design of garments. This creative practice research is based in my artisanal practice of fashion and textile design, which involves designing and making garments through all stages of development by hand. Material engagement describes the relationship between materials and their handling by practitioners. This complex relationship connects the intentions of the practitioner and their embodied interactions with what materials afford through their handling. Research in the practice of creative pattern cutting is concerned with identifying how creativity occurs through pattern cutting. However, the criticality of material engagement in the pattern cutting process has been minimally expanded upon by fashion designers. In my research, I have identified that material engagement is foregrounded through questioning the conventional notion of the pattern as a plan or template. In this article, I suggest how theories that critique the classical separation of form and material can support this foregrounding of material engagement in garment cutting. Dynamic Cutting is a new method of experimental cutting for fashion and textile design which emphasizes designing the surface and form of the garment at the same time. Dynamic Cutting evidences that textiles are an integral part of cut-led garment design and designer accounts can evidence the variety in approaches using materials when cutting. This research applies a creative practice research methodology which combines design practice research, critical design and reflective practice perspectives. This methodology serves to surface tacit understandings of materials and how material engagement and material affordances are integral to dynamic form creation processes when cutting garments.

The Engineering Design Research Center (EDRC) at Carnegie Mellon University has created a two-semester design course that integrates research and education though industrially sponsored design projects. Over each of the six semesters that the course has been taught, teams of undergraduate and graduate students have designed, fabricated, and delivered a new generation of wearable computers. The Wearable Computer Design course at the EDRC is cross-disciplinary and inter-departmental, drawing students from four colleges in nine disciplines including five engineering departments (chemical engineering, civil and environmental engineering, electrical and computer engineering, mechanical engineering, and engineering and public policy), architecture, computer science, industrial administration and industrial design, The students in this course learn about design theory and practice, participate in research, and successfully deliver products to sponsors. Furthermore, the students are exposed to the complete cycle of design from concept through initial theoretical modeling and design, multi-disciplinary design tradeoffs to manufacturing, and finally to customer satisfaction and user feedback. This class also serves as a testbed for learning about the needs of a multi-disciplinary design team, for anticipating the needs of geographically-distributed design teams, for reflecting on the interplay between product design and design process, and for evaluating the design tools and design methodologies that have been developed at the EDRC. The paper describes the evolution of the Wearable Computer Design course, the integration of design education, design research and design practice in an interdepartmental course. It also describes the interplay between disciplines, between theory, practice and education, and between designers and users.

Introduction. Control of waste management is a complex process that involves organizational-economic and economic-environmental components that are directly or indirectly related to the production and consumption of products, supply of raw materials, natural resources, related information and financial flows, etc. Transport and logistics occupy a special place among them, because of the specifics of waste as an object of management, as well as related issues of environmental pollution and the impact on the health of the population. Transport-logistics approaches are needed to allow the use of appropriate management levers and instruments aimed at solving a complex issue when production and associated material flows are considered in close connection with the movement of waste generated during production and consumption.&#x0D; Aim and tasks. The purpose of the article is to substantiate the conceptual approach to the management of transport-logistics processes in the field of responsible waste management on the basis of analysis of economic-ecological and organizational issues, and prospects of its development in Ukraine.&#x0D; Results. As a result of the research, it has been determined that reversible logistics is a means of achieving positive ecological-economic efficiency, the feasibility of which, first and foremost, of the transport component is confirmed by the fact that in the long run, Ukraine can significantly reduce the level of environmental pollution caused by the formation and placement of waste, but the volume of emissions in the transport sector will increase. Accordingly, it is necessary to increase the role of goal-setting functions and coordination of actions in the field of waste management; the main goal at the same time is to increase the ecological-economic efficiency of processes associated with transportation, as well as sorting, storage and disposal of household and industrial waste. This principle is the basis for integrating transport-logistics operations into a waste management system, the main elements of which are management functions and associated environmental-economic instruments for influencing waste management processes. The subsystem of ecological management within the framework of the waste management system, in particular, its transport-logistic component, which forms the ecological policy at micro and macro levels, deserves special attention; and is an effective instrument for implementing the concept of motivated liability.&#x0D; Conclusions. In the field of waste management, one of the top priorities is the task of increasing the role of transport logistics. Solving the problem of managing transport-logistics processes of responsible waste management is seen in two aspects: integration of the transport-logistics system into the waste management system at the territorial level; creating an economic space for mutually agreed solutions to issues of transportation and other logistics waste operations. This conceptual approach will create competitive conditions for the subjects of environmental-economic activities, which initiate the responsible management of waste in aspects of their transportation, sorting, utilization, etc. in accordance with ISO standards in the areas of waste and transport management and the environmental management system.

The Environmental Protection Agency (EPA) presented the Regulatory Determination on drilling muds, produced water and associated wastes to Congress on June 30,1988. One conclusion was regulatory gaps were present in some State oil and gas programs that compromised environmental protection. EPA believes they have authority under Subtitle D to fill these gaps. However, the Subtitle D type waste management guidelines, as being formulated by EPA to regulate mining operations and municipal landfills, are not viable or cost effective when applied to Oil and Gas Industry (0GI) operations. The existing drilling waste management practices used by the OGI in a number of State oil and gas programs though are viable and cost effective to ensure environmental protection. These existing practices as discussed in this paper can be implemented in applicable State programs to fill regulatory gaps.

The research work is a documentary study on the generation and management of waste in the Danube Delta Biosphere Reserve. Waste, the end result of anthropic activities, is a growing problem for environmental protection. Several types of waste are generated in the Danube Delta Biosphere Reserve. These include household waste, floating waste, agricultural and food waste, medical waste, etc. The quantities of household waste (a significant share of the total amount of waste) are monitored according to Government Decision no. 856 of August 16, 2002, on the records of waste management. Current waste collection, transportation and storage practices are not entirely appropriate. This generates a negative, sometimes significant impact on the environmental factors manifested in the reserve. Therefore, waste management requires the adoption of specific measures regarding the waste recovery and disposal in the area and beyond. The trends regarding waste management are focused on actions of prevention, recycling, reuse and recovery. These actions should lead to limiting the quantities of waste disposed of for storage, by selective collection; limiting the production of greenhouse gas (GHG) emissions; maximizing the rational and efficient use of natural resources. This research work refers, in particular, to the management of municipal waste within the territory of the Danube Delta Biosphere Reserve (DDBR).KeywordsWaste managementRecoveryDisposalEnvironmental protectionReserve

SummaryThis article explores the potential of RFID (radio frequency identification device) for improving the current waste and resource management system in Switzerland. It presents the following three possible options for utilizing RFID tags to support waste management processes: “at source automation” (using a “smart” trash can), “end of pipe I” (combination of the current system with an additional separation of recyclables before incineration), and “end of pipe II” (replacement of the current recycling infrastructure by sorting at the incineration plant). These options tackle the waste and resource management chain during different processes (i.e., waste generation, waste separation, and treatment). Based on an MFA (material flow analysis), we performed a multicriteria assessment of these options with experts from the waste management sector.The assessment of ten experts in the waste management field regarding the proposed options for batteries and electrical appliances showed that, from an ecological perspective, the implementation of RFID in waste management would be desirable and would lead to an improvement in the current recycling rate in Switzerland for the goods studied. From an economic perspective, new investments would be required in the range of 1 to 5 times the maintenance costs of the current separate collection system. From a social perspective, the utilization of RFID tags in the waste management process was ambiguous. In particular, the end of pipe II option would, on the one hand, significantly improve convenience for consumers. On the other hand, experts see privacy and, what is more, social responsibility as being under threat. The experts considered the ecological and social aspects to be more relevant than the economic ones, preferring the end of pipe I option over the other options and the status quo.

The reason for this statistical study is to conduct an analysis to extract barriers to market waste management in federal university Lokoja and its immediate environment, government and community response and its effectiveness. The study area is Federal university Lokoja, markets and the community that host the federal university Lokoja. Market activities (Buying, selling and consumption) can generate different kinds of hazardous and non-hazardous wastes to the surrounding. It was noticed that mismanagement of wastes often results ejecting dangerous chemicals to the environment and this causes health issues for human being. This waste can be inform of industrial chemical and market waste. Lokoja is the state capital of Kogi states, resource-constrained, policy &amp; implementation deprived, infrastructural inadequate and lacks the technical know-how when it comes to the efficient and sustainable management of market wastes. Past studies concluded that regulations and legislations focusing on waste management and environmental sustainability are not well formulated Lokoja, implemented nor adhered to by many people concerned. Moreover, wide loopholes and gap exist in waste generation, waste management practices and government policy. There is a lackadaisical attitude from government agencies in charge of waste management Lokoja. The services provided by these government agencies are described as being irregular. So far, waste management in Lokoja is the sole government responsibility. Furthermore, markets in Lokoja suffer from inadequate waste segregation, collection, storage, transportation and disposal practices which can lead to occupational and environmental risks. Knowledge and awareness regarding proper waste management remain low in the absence of training for agency staff and the market community. Overall, market waste management in Kogi state faces several challenges ranging from agency, policy, funding, facilities, implementation, adherence and health. For any sustainable development in Lokoja, proper waste management practices must be sustained and the harmful effects of wastes chemicals contained, hence Kogi state government must take action.
