The issue of solid waste management through recycling programs in Malaysia have long been discussed in the mainstream media. However, the issue is still not taken seriously since until today the recycling rate is still low about 11 percent compared to developed countries, which already exceeds 70 percent. The situation is alarming because of its implications on the health and size of landfill is increasingly limited. Therefore, this study aimed to investigate the level of customer awareness campaign supermarkets to recycle through the reward system through the use of automatic machines discharge bottle called Deposited Recycle Machine (ReDMac). Data were collected through a questionnaire and interviews. A number of respondents involved were 362 people and they were randomly selected from five different locations. The study found that 73.2% of respondents were aware of the recycling campaign held out of which 59.7% were admitted to participate in the recycling campaign, while 77.1% of respondents agreed with the reward system to encourage consumers to practice recycling. This study convinced that the best alternative is to recycle plastic bottle through the use ReDMac, as a new way to educate the society to love environmental.

The tremendous quantity of waste produced from construction and demolition is a major cause of environmental degradation. This quantity tends to increase due to the rapid growth of building development and renovation. Meanwhile, construction waste management is a complex and costly process due to the fact that it requires different kinds of resources such as money, land, and technology. It is often ignored by all project participants even though it is an essential element of construction project management. However, it has been discovered that modern construction waste management is structured based on the concept of circular economy which focuses on eliminating construction waste and maximizing the value of materials. Therefore, this research proposes an innovative framework to implement the circular economy using building information modeling (BIM) in order to improve the construction waste management process. This involved a thorough review of past literature to identify the implementation of the concept of circular economy, waste management, and the application of BIM, also the research gaps observed were used to develop the functionality of the proposed framework. The five functionalities include (1) visualization and data integration, (2) direct construction waste quantity take-off, (3) BIM-based sorting system and selection of appropriate disposal parties, (4) estimating cost and schedule of waste disposal, and (5) simulation and monitoring report. This BIM system was designed to analyze material waste, quantity, disposal time, and waste treatment based on project conditions, material quantities, and schedule. It can also be used to plan and monitor the construction waste process, thereby making it possible to avoid the disruption of productivity and project time usually caused by unplanned waste management activities. Moreover, the proposed on-site sorting system also has the ability to facilitate the adoption of the circular economy concept during the construction phase.

One of the characteristics of a healthy environment is properly waste managed. Densely populated are areas where waste management needs to be improved. Plastic bottle is one type of waste that is widely available in densely populated areas. This waste, is difficult to decompose in the environment, and has not been managed optimally. The use of plastic bottle needs to be reduce the problem of waste, among others, it can be used as a vertical garden media. The methods are discourse, discussions, demonstrations, and practice how to create the plastic bottles make to vertical garden media. The participants are non-productive people, they are housewives. An important result of the activity is that the participants have the understand, skills and ability to make a vertical garden independently. Plastic bottle waste becomes useful, no longer becomes garbage. Plastic bottles are a growing media for vegetable and medicinal plants, that can beautify and green the environment in densely populated areas. It is hoped that participants will develop their potential in managing the environment starting from home, and sharing skills with the surrounding community.

Cet article est une étude expérimentale pour de connaitre la caractérisation et la quantification des déchets solides ménagers du quartier de Faladié dans la commune VI du District de Bamako. A Faladié, comme dans la plupart des communes de Bamako avec comme problématiques environnementales majeures, une insalubrité alarmante, qui accentue en partie les maladies comme : le paludisme, la fièvre typhoïde, le choléra, les infections respiratoires, les anémies, .... C’est dans ce contexte que la présente étude, voulant résorber l’épineuse problématique qu’est la gestion des ordures ménagères, a été coordonnée pour connaitre « la caractérisation des déchets ménagers au niveau des dépôts intermédiaires et finaux d’une part ; et de contribuer à la mise en place d’un système de tri adapté à Faladié d’autre part ». L’approche méthodologique d’échantillonnage utilisée pour déterminer la taille d’échantillon de déchets à trier est définie par la production journalière d’ordures ménagères d’un échantillon de la population totale par catégorie en satisfaisant à un niveau de confiance de 95 %. Ainsi, le tri manuel a porté sur le contenu de deux (2) bennes de 7m³, un total de 14m³ d’ordures ménagères, soit 7382,7 kg. Dans ces conditions, l’étude a permis de dégager la caractérisation des ordures ménagères et de différencier les types de déchets valorisables de Faladié. En outre, nous avons déterminé qu’il est généré chaque jour 0,27 kg par habitant (soit 0,27 kg/habitant/jour). A la suite de l’étude, des propositions stratégiques ont été formulées à la Mairie de la Commune VI dans le sens de mettre en place un comité de gestion intégrée des déchets. This article is an experimental study for the characterization and quantification of solid household waste in the Faladie neighborhood in the commune VI of the District of Bamako. In Faladie, as in most of the communes of Bamako with major environmental problems, an alarming insalubrity, which accentuates in part diseases such as: malaria, typhoid fever, cholera, respiratory infections, anaemia, It is in this context that the present study, aiming to solve the thorny problem of household waste management, was coordinated to find out « the characterization of household waste at the level of intermediate and final depots on the one hand; and to contribute to the setting up of an adapted sorting system in Faladie on the other hand». The methodological sampling approach used to determine the sample size of waste to be sorted is defined by the daily production of household waste of a sample of the total population by category at a 95% confidence level. Thus, the manual sorting involved the contents of two (2) 7m³ skips, a total of 14m³ of household waste, or 7382.7 kilograms. Under these conditions, the study allowed us to characterize the household waste and to differentiate between the types of recoverable waste in Faladie. In addition, we also determined that 0.27 kilogram per inhabitant is generated every day (i.e. 0.27 kilogram/inhabitant/day). Following the study, strategic proposals were formulated to the Commune VI Town Hall to set up an integrated waste management committee.

Sorong is one of the most advanced and most populous cities in the province of West Papua, with a population of 2016 reaching 232,833 people and a population growth rate of 3.21 percent per year (BPS, 2016). As the most populous city, of course, the problem of waste becomes a significant threat, especially related to the increasing volume of waste production both from households and businesses and also the tendency to dispose of waste improperly that results in environmental pollution. The purpose of this study was to determine the extent of environmental pollution due to plastic waste in the City of Sorong, then look further at the management of mineral water plastic bottles, and determine what factors influence the amount of plastic bottle waste in the City of Sorong. The analytical method used in this research is descriptive qualitative analysis. Based on the results of the study it can be seen that the waste management process is carried out by several parties, among others: carried out by the Government using an integrated management system, then by the community with an individual management system, and by the private sector through the Sorong Raya Garbage Bank. Factors that influence the amount of plastic bottle waste include: The level of community / business actors' knowledge about waste, their attitude about waste management, their behavior in managing waste, and the activities of government administrators such as studies on waste, socialization of facilities and regulations, and the adequacy of the APBD budget. and also external participation.
