“…However, the functional implementation of LCCA depends on a variety of factors such as the availability of supporting project documentation, the degradation insights into the state of the infrastructure, and the availability of guidance for calculating usage costs [40,52]. Over the last decade, numerous research on LCCA has been performed to determine the cost of infrastructure projects [19,[53][54][55][56][57][58][59][60][61]. Most of the studies have concentrated on comparing products used in rigid and compact infrastructure or have sought to reduce the cost and the environmental effect of infrastructure by utilizing advanced, bio-based, or recycled materials [19,[53][54][55][56][57].…”

The comfort of human life depends on the quality, size, and reliability of the infrastructure projects. In the infrastructure systems, rapid growth is found, where the economic and sustainable impact has become a topic of significant concern for policies and government officials. To achieve con-straints of sustainable development, all the policies and actions over the infrastructure project's life cycle must be assessed. Decision-makers have adopted approaches for economic, social, and en-vironmental initiatives through Life Cycle Assessment (LCA) and Life Cycle Cost Analyses (LCCA) of infrastructure projects. The purpose of this review is to highlight the impact of per-forming LCA and LCCA in infrastructure projects. To achieve this goal, a systematic literature review methodology is adopted in which renowned databases, i.e., Web of Science, Science Direct, Emerald and Scopus were selected to extract the relevant literature. Using the PRISMA approach, 1251 publications were identified which were then filtered and 55 documents were included in the final review. In the extracted publications most, researchers were biased toward LCA and LCA individually, whereas few focused on integrated LCA and LCCA. The researchers assessed the costs and impact associated with the infrastructure project while there were less focused on the environmental cost. Besides this, techniques of economic, social, and environmental growth of infrastructure projects have been emphasized during the design phase because of substantial relations between infrastructure design and operation management. Moreover, a conceptual framework has been developed that will assist the decision-makers to consider the effects of LCA and LCCA on various aspects of the infrastructure project and how it impacts sustainability. In the last, a case study was performed to assess the developed framework with the incorporation of environmental impact cost.

“…The main advantages of AD technology to a circular economy include cost savings, closing production-to-waste loops, and increasing the reuse and recycling of bioenergy and biomaterial. 37,38 The circular economy is also a conceptual model widely used in waste management, 39 and agroindustrial waste is a feedstock well suited to play a role in sustainable development based on the bioeconomy. 37 With the growing demand for energy, the biogas produced can be a substitute for fossil fuels, reducing environmental impacts and contributing to the energy matrix decarbonization.…”

This study aims to evaluate the Brazilian production of açaí, focusing on its waste generation and addressing mass and energy balances arising from its cultivation, extraction, processing, and waste disposal. A new technological route for açaíʼs waste management was introduced for bioenergy recovery based on the circular economy concept. In 2018, Brazil produced 1.7 million tons of açaí fruit for an income of 1.07 billion USD, and the associated waste generation (seeds) was estimated at 85%. Due to the high production of waste, an innovative approach was developed for a system boundary (conceptual line that divides the system), including the management of solid and liquid wastes through anaerobic digestion (AD). The results showed that, from 1 ton of açaí fruit fed into the facility for processing, 1.2 ton of solid waste and wastewater was generated. This waste was submitted to AD and produced 2.77 m3 of biogas, with a methane composition of 50%. The complete industrial process demands 25 kWh per ton of frozen pulp. The local energy produced by the biogas burning could be recycled and used by the process, establishing a circular energy economy for this sector. With the adoption of AD waste management, about 61% of the external electricity requirement for the açaí fruit processing can be replaced from the biogas produced. The adoption of this technology can be contribute to decarbonization. Furthermore, the implementation of AD could support the transition to a circular economy, with environmental, social, and economic benefits for local and regional sustainable development. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd

“…The IRR [21] together with the information from local recycling cooperatives and the NGO allied to the recyclers' sector detail the socioeconomic reality of waste pickers. There are quite a few studies on this topic stemming from Latin America [40,[60][61][62][63]. So far, however, there are no scientific studies regarding the contribution of urban mining to the reduction of emissions in Ecuador.…”

Environmental and Socioeconomic Impacts of Urban Waste Recycling as Part of Circular Economy. The Case of Cuenca (Ecuador)

2020

View full text Add to dashboard Cite

Urban mining by recyclers represents a positive environmental impact as well as being part of the waste management chain. This paper analyzes the contribution of waste pickers in the city of Cuenca in Ecuador and the conditions of their activity. This research has a two-fold objective. First, it calculates the reduction of greenhouse gas emissions resulting from the substitution of virgin raw material in the production process by using recycled urban waste. The second objective is to conduct a socioeconomic analysis of the workers involved in the urban waste sector. Cuenca (Ecuador) is the main city used for this case study, thanks to the accessibility of a rich database built from the survey conducted by the NGO Alliance for Development. The information contained in this survey facilitates the identification of potential consumers of the waste industry. This study uses Clean Development Mechanism methodology. Finally, this work proposes a theoretical model for solid waste management, applied to the city, following the principles of the circular economy.
