GEOGRAPHIES OF EXCLUSION: Reproducing Dispossession and Erasure within a Waste Picker Organization in Mumbai

A rich seam of waste scholarship already addresses the exclusion faced by informal waste workers as cities in the global South undergo spatial transformations to become ‘world class’. However, less attention has been paid to how state practices have reproduced inequalities within and across waste picker communities. Drawing upon eleven months of ethnographic research at Mumbai's Deonar dump site, this article maps the practices through which waste workers have responded to their exclusion following a massive fire in 2016. It demonstrates that social exclusion is experienced differently by different members of the community and calls for a greater focus on heterogeneity amongst waste workers. Multi-dimensional vulnerabilities manifest through these workers’ deal-making strategies, while simultaneously mirroring the conditions of marginality produced by the state. The article contributes to debates on marginality by employing the lens of erasure to show how exclusion relies on the optics of visibility and invisibility. By unpicking the hierarchical structure within one waste worker organization, the article argues that the state-led mandate for garbage-free cities in India disproportionately affects those located at the margins of marginalized groups.

Food waste in the retail sector: A survey-based evidence from Central and Eastern Europe

This paper explores the issue of food waste in the Lithuanian retail sector. A questionnaire survey was designed in order to collect the relevant data from both the largest retail chains with stores around the country and companies with small-scale stores in rural areas. The present case is interesting as the literature on Central and Eastern European countries is scarce in the sense of the quantification of food waste. In this paper, the amounts of food waste among different food product categories are discussed and then extrapolated to approximate food waste in retail trade for Lithuania by using sales revenue as a key parameter. The results suggest that food waste in the Lithuanian retail sector amounts to 36.4 thousand tonnes or 13.0 kg per capita per year. Fruits and vegetables account for more than a half (63%), whereas meat (products) come next representing some 9% of food waste. Therefore, these products can be considered as the major targets for valorisation schemes and other measures aimed at mitigation of food waste.     

垃圾焚烧发电项目建设管理重难点分析及措施

针对于我国城市化建设和发展,可以用飞速这一词语来形容,但是在快速建设发展的这一过程中也产生了很多城市生活垃圾,就目前来看,所采用的处理方式主要以垃圾焚烧发电建设项目为主。对于垃圾焚烧发电建设项目而言,可以说是生活垃圾处理的一个有效方式,但由于受各方面因素的影响,在实际建设过程中经常可以看到一些潜在风险和问题的出现。基于此,本文就垃圾焚烧发电项目建设管理模式及重难点分析及措施进行了研究分析。
