Valorisation of used cooking oil sludge by codigestion with swine manure.
Published in Waste management (New York, N.Y.)
The addition of lipid wastes to the digestion of swine manure was studied as a means of increasing biogas production. Lipid waste was obtained from a biodiesel plant where used cooking oil is the feedstock. Digestion of this co-substrate was proposed as a way of valorising residual streams from the process of biodiesel production and to integrate t...
Greenhouse gas emissions from landfill leachate treatment plants: a comparison of young and aged landfill.
Published in Waste management (New York, N.Y.)
With limited assessment, leachate treatment of a specified landfill is considered to be a significant source of greenhouse gas (GHG) emissions. In our study, the cumulative GHG emitted from the storage ponds and process configurations that manage fresh or aged landfill leachate were investigated. Our results showed that strong CH4 emissions were ob...
Home composting versus industrial composting: influence of composting system on compost quality with focus on compost st...
Published in Waste management (New York, N.Y.)
Stability is one of the most important properties of compost obtained from the organic fraction of municipal solid wastes. This property is essential for the application of compost to land to avoid further field degradation and emissions of odors, among others. In this study, a massive characterization of compost samples from both home producers an...
Dynamic stock and end-of-life flow identification based on the internal cycle model and mean-age monitoring.
Published in Waste management (New York, N.Y.)
Planning of end-of-life (EoL) product take-back systems and sizing of dismantling and recycling centers, entails the EoL flow (EoLF) that originates from the product dynamic stock (DS). Several uncertain factors (economic, technological, health, social and environmental) render both the EoLF and the remaining stock uncertain. Early losses of produc...

Coffee husk composting: an investigation of the process using molecular and non-molecular tools.
Published in Waste management (New York, N.Y.)
Various parameters were measured during a 90-day composting process of coffee husk with cow dung (Pile 1), with fruit/vegetable wastes (Pile 2) and coffee husk alone (Pile 3). Samples were collected on days 0, 32 and 90 for chemical and microbiological analyses. C/N ratios of Piles 1 and 2 decreased significantly over the 90 days. The highest bacte...
Review of LCA studies of solid waste management systems--part I: lessons learned and perspectives.
Published in Waste management (New York, N.Y.)
The continuously increasing solid waste generation worldwide calls for management strategies that integrate concerns for environmental sustainability. By quantifying environmental impacts of systems, life cycle assessment (LCA) is a tool, which can contribute to answer that call. But how, where and to which extent has it been applied to solid waste...

Application of an early warning indicator and CaO to maximize the time-space-yield of an completely mixed waste digester...
Published in Waste management (New York, N.Y.)
In order to increase the organic loading rate (OLR) and hereby the performance of biogas plants an early warning indicator (EWI-VFA/Ca) was applied in a laboratory-scale biogas digester to control process stability and to steer additive dosing. As soon as the EWI-VFA/Ca indicated the change from stable to instable process conditions, calcium oxide ...
