“…This has created inefficiency in production and consumption and generated a significant rate of waste [5]. Waste management has been a special focus for cities and their urban infrastructure, including in construction [6,7] In many developing countries, improper city waste management systems offer a focus for circular metabolisms, which, simultaneously, can help to increase the cities' resilience [8].…”

“…Our study confirms that waste management could be one priority area for CE implementation in Indonesia at any city level. Here, our analysis interprets a city in its entirety as a living system with the dynamic ability to overcome the resource challenges in in order to function well [6]. Understanding this dynamic is important in getting to know how best to view a city in order to comprehend its structure and its urban living functions.…”

The role of the circular economy has attracted increased attention amongst practitioners and policymakers in recent years. It has been broadly developed and applied at different levels (micro, meso and macro) in developed countries. However, to date, the possibility of a circular economy in Indonesia has not been widely explored or discussed by city actors. This gap in research represents an opportunity to investigate options that may foster the adoption of circular economy principles and practices. Which aspects of the circular economy should be of primary concern, considering Indonesia’s current situation? In response to this question, this paper offers a systemic process of lessons learnt as developed from the literature, identifying certain key aspects that could benefit Indonesia. This study mapped important factors and key indicators that have been claimed to have beneficial effects in the application of circular economy principles in cities. The authors developed a protocol to systematize the literature review process to illustrate gaps and to provide and recommend indicators for circular cities. These are equally applicable to the local situation in North Kalimantan, which we selected as a showcase medium-sized city. Empirical data was collected by interviewing different stakeholders to enrich the theoretical set of circular economy indicators. This case study offered the opportunity to gain a more realistic understanding of what circular cities might look like in the Indonesian situation. The findings allowed us to explore and describe the current circular economy city-level discussion. They also provide insight and information for decision-makers and city actors on how to collaborate to develop a framework to advance circular city initiatives.

“…According to Rahim et al, (2013), polyethylene plastic wastes are best utilized in cement, sand, aggregate, concrete, and other construction materials. It also helps in reducing the cost of concrete manufacturing (Rahim et al, 2013), and helps increase the strength, hardness, and resistance of concrete materials (Tamrin & Nurdiana, 2021) thus, increasing construction safety (Treceñe, 2019). The concrete workability indicates the consistency of the concrete mix during the process.…”

“…The concrete workability indicates the consistency of the concrete mix during the process. The use of plastics as additives to the concrete mixture has affected the compaction caused by the contact with the surface and the internal friction (Tamrin & Nurdiana, 2021). Further, considering that plastics are lightweight and resistant to weather, therefore, plastics are good additives materials for concrete.…”

In recent times, the production of polyethylene ground plastics has increased markedly in the Philippines. However, current levels of their usage and disposal generate several environmental problems. Recycling is one of the most important actions that are being made to reduce these impacts. The present study used polyethylene ground plastic wastes to investigate their possible use as plastic aggregate in concrete application. The shredded plastic wastes were used in concrete with partial replacement of ½ kg and 1kg by volume of conventional coarse aggregate. Three types of concrete specimens including one without plastic aggregate were used in the study for comparison. All the concrete specimens were tested for their different mechanical properties after a curing period of 28 days. Various physical properties of all aggregates and fresh concrete properties were also tested in the laboratory, these include pound per square inch (psi), Mega Pascal (MPa), Kilo Newton (KN), and the type of fracture. The test for psi, MPa, and kN resulted that concrete mixtures with 1kg ground plastic produced the best result among the three samples having 3150 Psi, 21.7 MPa, and 395.7 KN, respectively. Moreover, the specimens were loaded under a monotonic uniaxial compressive load up to failure by using MATEST hydraulic testing machine with the indicator of kN. The result showed that both standard mixtures of concrete and the standard mixture of concrete with ½ kg polyethylene ground plastic have a comparison infraction that has a result of an SW-Shear Wedge of Type 5, while the standard mixture of concrete with 1kg polyethylene ground plastic has a conical type of a fracture. Based on the several tests conducted, it is concluded that the standard concrete mixture with 1kg polyethylene ground plastic provided the best result compared to other specimens. Furthermore, the use of polyethylene ground plastic waste in the standard concrete mixture provides some advantages like on reduction of plastic wastes, prevention of environmental pollution, and energy saving.

This article develops an idea of mechanical recycling of polymer wastes. Unlike previous research studies, which are dedicated to the study of the physical and mechanical properties of fibrous concrete and the technology of its manufacturing, this work considers a specific construction product—laminated concrete column made of recycled polyethylene terephthalate (PETF). Currently, there are no policy documents (standards or codes) regarding the engineering design of such constructions. Therefore, the authors’ attention is focused on mechanical and mathematical modeling of the laminated column behavior under operational load. An analytical study of two-layer PETF-concrete column’s stress-strain state was performed, taking into account the contact interaction between inhomogeneous layers of the materials. It has been determined that, in certain circumstances, the contact pressure between the layers can have a significant effect on the load-bearing capacity of the column. In general, a method of engineering assessment of laminated columns’ load-bearing capacity was developed.
