Finding an effective framework for the consumption of municipal and construction/demolition wastes has been the main research consideration for decades. For different categories of wastes, there is a need for the development of working systems for cleaner utilization of the materials. This study is focused on the review of composite development using paper waste and pulverized ceramics. The issues discussed comprises; excessive waste production, the building sector’s ecological effects, paper waste availability, and proposed solutions to realizing a sustainable built environment. The study also discussed standard mortar and the various types that exist, lightweight mortar, its nature, intricacies of its production process, and the prior use of waste materials for its manufacture. Paper waste, although not having enough strength as conventional aggregate, but with its filling effect, could fit lightweight mortar production along with other similar aggregates. The study gave an overview of the methodological deficiency found and proposed viable approaches to combat these gaps and further advance sustainable and eco-friendly construction.

Background: In Iranian Traditional Medicine, Boswellia serrata oleo-gum resins were used for the treatment of "Nisyan". "Nisyan" was equivalent to a reduction of memory or forgetfulness. Objective: This review evaluates the traditional believes of B. serrata and memory and its effectiveness on memory loss. Methods: We extracted all traditional and modern information on B. serrata oleo-gum resin preparations and memory from scientific accessible resources (Google Scholar, PubMed, Springer, Science direct, Wiley), non-accessible resources and traditional books. Results: In traditional manuscripts, "Nisyan" is equal to memory loss in modern medicine and was believed to happen as the result of pouring the waste materials into the brain. Traditional practitioners treated "Nisyan" by inhibition of waste production in the brain or cleaning the brain from waste materials. They recommended using the plants with warming effects on the brain. It was believed that B. serrata had beneficial effects on memory functions and its memory enhancing effects have been the subject of pharmacological and clinical trial studies. Conclusion: Despite some documents on the effectiveness of B. serrata oleo-gum-resin on memory functions, there is gap between these investigations, especially in pregnant and nursing mothers. More investigations with large clinical trials are required to complete flaw in order to improve the therapeutic applications of B. serrata on memory functions.

Selection Of

The direction of the implementation of this study is to reduce dependence on natural resources and preserve them from extinction, especially timber natural resources. Green design content is a systematic implementation in each stage. An initial idea was to find an alternative building material that was environmentally friendly. One of the implementations is conducting experiments on panel production from paper waste materials. Paper panels that have the same capabilities as pre-existing panel products. The aim is to make it an interior design material for building, both for construction and aesthetic functions. The consideration of the selection of panel materials is the wide scope of utilization, flexibility, easy treatment, and factors of people who are used to it. In full, this type of paper waste contains forms that are fatty, limp and fragile. This character strongly supports the implementation of that perception. Furthermore, this character becomes a stimulus to bring up the manufacturing method, which is a vertical cross-configuration, which uses limp and fragile sheet paper and then arranged into a panel area with a thickness of 20 mm which requires hard, sturdy, and strong properties.

Circular economy (CE), the new ‘buzzword’ in urban and regional studies and policy debates, is about shifting from a linear production process towards a circular one in which the generation of waste is minimised, materials circulate in ‘closed loops’, and waste is not considered a burden but rather a resource that brings new economic opportunities. However, while there is a consensus on the need to facilitate a transition towards a circular economy, the governing of this endeavour remains extremely challenging because making a circular economy work requires cutting across sectoral, scalar, and administrative boundaries. Drawing on the sustainability transitions literature and the case of the Amsterdam Metropolitan Area, arguably one of the frontrunners on the strive towards a circular built environment and economy, the paper seeks to identify and understand barriers for CE transition at a regional scale. The findings underscore the multi-faceted nature of the challenge and offer lessons for the governance of emerging regional circular spatial-economic policies.

Process planning is part of the general product development and production process that usually follows design and precedes manufacturing. Manufacturability and process planning information in general play central role in many product development and production activities, including paradoxically, conceptual and detail design - the activities that take place before process planning. The need of conducting some of the process planning activities formally before or during design is thus rather obvious. One of the main research issues is therefore the identification of the process planning activities that can be performed before the traditional process planning phase and handling of the process planning information so as to adequately provide the designers with the manufacturability informationneeded during conceptual and detail design. Another issue is how to support collaboration during process planning and how to maintain continuity of the process planning tasks. This paper suggests the decentralization of the process planning task and proposes the execution of the process planning activities in a piecemeal fashion, starting right afterreceiving an order and specifying the requirements for a product. Process planning under the proposed procedure consists of six semi-autonomous sub-phases, some of which comprise activities that must be conducted prior to the process planning phase. This helps to overcome the problem of timely availability of manufacturability information during the execution of upstream and downstream product development and production activities. The paper alsoproposes a computer-based method of handling the manufacturability information generated in various stages of the product development and production process. A database design and structure of prototype software that manages the process planning information are presented and discussed. Furthermore, a case study conducted to explore howthe proposed process planning procedure could be put in use is presented and discussed.

Natural dimension stone processing generates large volumes of stone waste, which have a significant impact on the environment, as well as on the efficiency and profitability of the stone-processing plant. The article presents the characteristics of waste produced as a result of natural dimension stone processing and the structure of the waste production process. Solid stone scraps and sludge were distinguished. On the basis of the performed analyses, it was shown that stone waste constitutes 10–35% in relation to the quantity of the processed stone material, with the quantity of sludge being even threefold greater than the volume of solid scraps. According to the circular economy principles, the aim should be to reduce the amount of waste generated by reducing primary resources in favour of secondary material. Reducing the volume of stone waste is possible through rational planning of stone production while at the same time maximising the efficiency of stone material usage and introducing the most modern processing machines. This significant volume of stone waste encourages efforts to find solutions for both its management and reduction. This paper reviews the utility potential of stone waste. Sensible use of waste is important to increase the profitability and productivity of processing plants while incentivising environmental protection.

Activities of Industry can potentially be the pollutant and harm the environment if it is not managed properly and can be detrimental to the industries, people and the environment. One of them is the food industry that produces raw materials of products and waste from the production process in the form of hazardous and toxic materials waste. This research uses descriptive approach that aims to evaluate industrial activities that produce toxic materials and hazardous waste. The management and utilization of toxic and hazardous waste materials require the consent of the ministry of environment based on Regulation of Government number 101 of 2014. The method of utilization of toxic and hazardous waste materials that have been applied in other industries can be applied in the food industry. This utilization method is required for the management and utilization of toxic and hazardous waste materials in the food industry because the waste is not utilized or recycled, only stored in a temporary storage warehouse and later sent to the container
