“…Renca has an average monetary income per capita of approximately half of the average in the city of Santiago and nearly 85% of the population belong to the lowest socioeconomic level (Plan de Desarrollo Comunal, 2015). Therefore, in this study, the waste generation rate is differentiated by socioeconomic status, in which 1.00 kg/person-day, 1.14 kg/ person-day, and 1.48 kg/person-day is assigned to low-, medium-, and high-income users (Blazquez and Paredes-Belmar, 2020). The waste produced in Renca is characterised by organic waste (45.8%) and recyclable waste (34.7%) mainly as paper, plastic, metal, and glass.…”

“…Usually, this waste collection practice is based on practical experience and intuition, and collection sites are manually selected (Kao and Lin, 2002). As a result, waste collection becomes inefficient, yielding high operational and transportation costs, low citizen satisfaction, and negative effects on society and environmental conditions as waste is left scattered on roads and sidewalks (Arribas et al, 2010; Blazquez and Paredes-Belmar, 2020) or abandoned at illegal dumping sites (Morales, 2016; Vásquez, 2011). As an alternative to the current waste collection practice, waste bins are appropriately located throughout Renca, contributing to a more efficient and effective bin-to-bin waste collection process.…”

In the commune of Renca in Santiago, Chile, the household waste is currently collected on the kerbside and then thrown in the rear of a compactor truck. This system becomes inefficient when not all citizens are always serviced, yielding high overall collection costs and negative impacts on the environment and the society. Recently, recyclable waste collection sites have been situated throughout the commune, which need to be examined with respect to population coverage and average travel distances to these sites. This study employs mixed-integer linear programming models and geographic information systems to solve the bin location–allocation problem for household and recyclable waste separately. The results are shown for different values of waste generation, bin capacities, and travel distances, in addition to considering the users’ and municipality’s preferences in the decision-making process. The proposed recyclable waste bin locations present a more efficient solution than the existing collection sites in the commune of Renca since more users are serviced within a shorter travel distance to dispose of their recyclable waste.

“…Such a choice of granularity aligns with the literature on waste generation, where few studies have explored higher spatial granularities ( Cheniti et al, 2021 ). The partition of a city into smaller spatial units is traditionally done through administrative or statistical divisions, such as household ( Villalba et al, 2020 ) or census blocks ( Blazquez & Paredes-Belmar, 2020 ). For instance, Johnson et al (2017) developed a gradient boosting model to predict waste generation at the level of census sections in the city of New York (USA); Solano Meza et al (2019) used machine learning models to predict waste production at the level of waste collection zones in the city of Bogotá; Mushtaq et al (2020) analyzed the spatial-temporal variation and forecasting of municipal solid waste in the city of Srinagar (India) at ward level.…”

Impact of COVID-19 lockdown measures on waste production behavior in Lisbon

et al. 2022

The recent restrictions on mobility and economic activities imposed by governments due to the COVID-19 pandemic have significantly affected waste production and recycling patterns in cities worldwide. This effect differed both between cities and within cities as the measures of confinement adopted by governments had diverse impacts in different areas of cities, depending on their characteristics (e.g., touristic, or residential). In the present work, mixed waste collection areas were created, based on waste collection points, that define spatial units in which contextual data such as tourism and residential characteristics were aggregated. The difference in mixed waste collected compared with previous years was analyzed along with the impacts on recycling due to the modification in operations regarding waste collection during the lockdown. The results showed that despite the suspension of the door-to-door recycling system during the lockdown, this did not translate into an increase in the production of mixed waste, and the recycling levels of previous years have not been reached after the lockdown, indicating a possible change in recycling habits in Lisbon. The touristic and non-residential mixed waste circuits presented significantly reduced mixed waste production compared to the non-pandemic context. Also, tourist, mobility, and economic activity were measured to understand which factors contributed to waste production changes during the COVID-19 pandemic. While little evidence of a relationship with these exogenous variables was found at the citywide level, evidence was found at the waste collection circuit level.

“…Waste management in communes is the responsibility of the local municipalities, where each independently manages their system. The current waste collection system in these municipalities consists of a door-to-door collection, using a truck transportation system [47]. The cost of the waste management system and clean public services in Santiago is approximately 208,967,339 M€, representing 7.28% of the total municipal budget [48].…”

Waste Management. The Disconnection between Normative and SMEs Reality

et al. 2021

View full text Add to dashboard Cite

Waste generation is a critical factor in global environmental degradation, where SMEs have been historically relevant yet underestimated. This study covers the issue of the disconnection between the normative and SMEs reality. Therefore, this research aims to investigate the relationship between waste management norms and their application in Chilean SMEs. For context, Chile is the nation that generates the most amount of waste per capita in the region. Nevertheless, the country also has one of the most rigorous waste frameworks in the region, by means of the Extended Responsibility Producer (ERP) law, which has been gradually implemented since 2016. Data for the study were collected through in-depth interviews with 25 SMEs. The results show the practical limitations of SMEs in complying with the waste law, the lack of traceability in the waste management system, and the need for economic support and technical assistance to improve the use and management of sustainable raw materials. Therefore, this study contributes to the limited knowledge of how SMEs implement waste management norms and their importance in diminishing waste generation and promoting waste hierarchy.
