“…This led to the development of the landfill mining (LFM) concept, which constitutes an important technological toolset of processes that regains resources and redistributes them. Simultaneously reduction of environmental contamination spread and other threats for human health possibly emerging from former dump sites and landfills is done [3,18]. 'Classical LFM' is a useful technology to discover hidden resources and look at the big picture of resources from the local, regional and global perspectives.…”

For decades, significant work has been conducted regarding plastic waste by dealing with rejected materials in waste masses through their accumulation, sorting and recycling. Important political and technical challenges are involved, especially with respect to landfilled waste. Plastic is popular and, notwithstanding decrease policies, it will remain a material widely used in most economic sectors. However, questions of plastic waste recycling in the contemporary world cannot be solved without knowing the material, which can be achieved by careful sampling, analysis and quantification. Plastic is heterogeneous, but usually all plastic waste is jointly handled for recycling and incineration. Separation before processing waste through the analytical approach must be applied. Modern landfill mining and site clean-up projects in contemporary waste management systems require comprehensive material studies ranging from the macro-characterization of waste masses to a more detailed analysis of hazardous constituents and properties from an energy calorific standpoint—where, among other methods, thermogravimetric research coupled with life cycle assessment (LCA) and economic assessment is highly welcomed.

Expansion of the Waste-Based Commodity Frontier: Insights from Sweden and Brazil

Waste is a valuable commodity and remains a livelihood source for waste pickers in the global South. Waste to Energy (WtoE) is often described as alternative to landfilling, as it provides cheap fuel while making waste disappear. In some European cities, this method has evolved into an impediment, slowing down the adoption of more sustainable technologies and waste prevention. These plants typically strain municipal budgets and provide fewer jobs than recycling and composting, thereby inhibiting the development of small-scale local recycling businesses. We applied the idea of ‘waste regime’ with an interdisciplinary and situated lens to provide insights to the following questions: How do different political developments in Brazil and Sweden, frame and reframe waste incineration and energy recovery, in the context of sustainability and waste management on local, regional and national levels? What forms of resistance against WtoE exist and what are the arguments of these protagonists? We evaluated the impact of WtoE and compare it with other waste management options with regard to CO2 balances and general environmental and social impacts. We conclude by suggesting more socially and environmentally appropriate ways of waste management, particularly for the context of global South cities.

“…The case studies are typically described in terms of the mass of landfill waste and seldom in terms of more specific information such as area, depth, and density. Without such information, the effect of excavation and internal transport logistics to the economic performance of LFM may be overlooked (Hogland et al, 2018;Hölzle, 2019). In terms of waste composition, it is typically presented by material fractions (e.g.…”

“…The average of waste compositions from different landfills is used to represent continental (Van Vossen and Prent, 2011), national (Ford et al, 2013;Frändegård et al, 2015), and regional levels (Damigos et al, 2016;Danthurebandara et al, 2015b;Van Passel et al, 2013). Clearly, there is a large uncertainty to be accounted for, both within and among reported waste compositions (Hernandez Parrodi et al, 2018;Hogland et al, 2018;Hölzle, 2019).…”

Assessing the Economic Potential of Landfill Mining: Review and Recommendations

et al. 2019

As landfill mining (LFM) gains public attention, systematic assessment of its economic potential is deemed necessary. The aim of this review is to critically analyze the usefulness and validity of previous economic assessments of LFM. Following the life cycle costing (LCC) framework, (i) the employed methods based on goal and scope, technical parameters and data inventory, and modelling choices were contrasted with respect to (ii) the synthesized main findings based on net profitability and economic performance drivers. Results showed that the selected studies (n=15) are mostly case study-specific and concluded that LFM has a weak economic potential, hinting at the importance of favorable market and regulation settings. However, several method issues are apparent as costs and revenues are accounted at different levels of aggregation, scope and scale-from process to sub-process level, from private to societal economics, and from laboratory to pilot-scale, respectively. Moreover, despite the inherent large uncertainties, more than half of the studies did not perform any uncertainty or sensitivity analyses posing validity issues. Consequently, this also limits the usefulness of results as individual case studies and as a collective, towards a generic understanding of LFM economics. Irrespective of case study-specific or generic aims, this review recommends that future assessments should be learning-oriented. That is, uncovering granular information about what builds up the net profitability of LFM, to be able to systematically determine promising paths for the development of cost-efficient projects.
