The amount of garbage that humans generate is rapidly increasing, and it will be impossible to control without radical adjustments. Such increases will have a significant impact on waste management firms, since they would be required to supply resources for garbage collection with little or no money. The goal of this project is to create a smart real-time waste controller system using the conceptual model of a smart electronic bin, which can be built by maximizing resource efficiency and optimizing the resources. This smart garbage bin prototype can automatically open the lid when it recognizes persons who wish to dispose of their trash. Even if people wish to dispose of their trash, if the waste bin is full, the lid will not open. It can also segregate plastic and non-plastic wastes. This smart bin is equipped with additional components such as GPS and GSM, for showing the location and to send alert messages. It can also detect the amount of trash in the garbage bin. The percentage-level of waste inside the bin is determined using an ultrasonic sensor. This data is delivered to a cloud-based monitoring and analytics IoT platform

The usage of plastic has been increasing from year to year for its durable, lightweight, sturdy, easy to form, and low cost production, so that plastic becomes a popular material. Plastics have affinities with persistent organic pollutant such as PCB, DDT, PAH and phthalates that can damage the ecosystem as well as harm to human. In this study plastic wastes were collected using nets in seven stations along Baturusa watershed, sorted based on its composing resin (RIC), then measured the abundance and the density rate on each station. 36% of the collected plastic wastes are Polypropylene (02), and 24% are LDPE (04). The highest density rate of collected plastic wastes was found on Mabet river (1.36 x 102 items/m3), followed by Baturusa river, and Rangkui river estuary. These three stations are located near the settlements so that the source of the plastic wastes comes from domestic activities. The variety of waste management showed a significant impact to the amount of plastic wastes on waters. One of the plastic waste management for the settlements is to carry out 3R (reduce, reuse, recycle), such as waste bank programs and implement EPR (extended producer responsibility) programme. The successfulness of this programme can only be achieved by the active participation of the waste bank customers and the implementation of 3R principle in daily life.

Plastics production (i.e 450 million tons per annum globally), use and disposal (i.e 300 million tons per annum globally) are one of the top environmental concerns and global waste management impediments. Nevertheless, nearly 90% of all plastics ever produced to present has never been recycled. Over the past decades, researchers’ voices have repeatedly been raised for acting and saving inland as well as aquatic ecosystems being harmed by the increasing plastic pollution. Microplastics have been reported by several studies to be in tap water, bottled drinks and in fish we eat. Consequently, conventions and agreements have been signed, laws and regulations enforced (banning, increased taxation, etc) in various regions and countries across the globe for lessening plastics harm on the environment. In this struggle, Rwanda looks to be in front line in beating plastic pollution crisis compared to other regional and continental countries; hence resulted in calling its capital Kigali by many, “the Africa’s cleanest city”. This success behind plastics break free could be attributed to Rwanda’s current strong institutional, political will (promotion of plastic recycling and reuse), legal frameworks (e.g non- biodegradable plastic bags ban, outlawing of single-use plastic items, penalties, severe fines, etc) and active citizens (e.g monthly community works also known as umuganda etc) in terms of eliminating plastic pollution, foster socio-economic development and environmental protection. These strategies do not only protect the environment but also save the money that the government would spend in cleaning the cities and facilitate the advertising of the country for its eco-friendliness; resulting in its tourism development. Recently, similar initiatives of reducing or banning plastics have been taken by several governments in African ,, lower-income countries and developed ones from other regions across the globe due to either limited recycling facilities, inadequate plastics trash disposal or as a solution to overcome the increase of plastic pollution which harm humans, farm animals, aquatic lives (fishes, sea turtles, etc), and the environment health. Thus, the present paper reviews the current knowledge of environmental impacts of plastics, approaches adopted for alleviating the harm from plastics in Rwanda and their implementation procedures which gave credits to the country on global environmental protection scene so that lessons from these practices can be implemented by other countries which aim at reducing plastics waste and associated pollution. The current solid waste management (i.e mainly plastics) and challenges are also discussed in order to be addressed by the authority in charge. Data and literature were retrieved from peer-reviewed journal articles, websites, books, reports, dissertations, local and international online newspapers. Despite significant efforts made towards a plastic free country, less has been written on plastic pollution in Rwanda; making it difficult to get reliable data and information for quantifying past impacts of plastic wastes. Furthermore, to the best of our knowledge no scientific research or report has been so far conducted to prove how plastic wastes contributed over the past years to flooding, prevented crops from growing, to what extent plastic litters have restrained rainwater from penetrating various soil types and other forms of plastic pollution in the country. Such studies are paramount for scientifically justify the ban initiatives in the country. This review resulted into encyclopedia that other researchers can build on to better understand environmental impacts of plastics to learn best plastics management practices for a sustainable environment.

This study elucidates the current state of plastic waste management in urban areas of Ghana, with a particular focus on Madina-La Nkwntanan municipality. As a result of the current uncontrollable plastic waste challenge, the Government of Ghana, is seeking sustainable approaches to reduce th effect of plastic waste in the country. A number of arrangements, including various forms of privatization, tax regimes and public-private partnership have already been initiated as first step solutions to the challenge, yet management of plastic waste, has not been encouraging. Using a case study from one municipality in Ghana, this paper shows that domestic plastic wastes forms the second most generated wastes in the study area. The results show that the practice of separation at source, which is the first step toward dealing with plastic waste, was uncommon in the study area, although pockets of houses in the municipality and other places in the country practiced it. This article proposes the integrated waste management (IWM) concept, as one of the possible sustainable options that could help tackle the plastic waste issue in municipality. This is in view of the sustainable nature of the concept as well as its integrative way of dealing with waste. This reality has been confirmed by other authors in several countries.

Inefficient solid waste management of plastics and polymeric materials is one of the global challenges leading to environmental deterioration. This challenge has brought alarming concern to minimize volume of such wastes released into the environment. The concern proposes a solution to the existing problems to some extent by reuse, recycling, and efficient conversion of waste materials into alternative application. Chemical and thermo-mechanical conversion of plastic wastes into energy and their biodegradation were taken into account. Consequently, some newly employed recycling and conversion techniques of plastic wastes, and possible future alternatives with recommendations are reviewed in this article
