Prioritize Diversion of Biodegradable Waste from Landfills

Methane Generation and Capture of U.S. Landfills Nickolas J. Themelis and A.C. (Thanos) Bourtsalas

This study was based on the hypothesis that, on the average, methane generation is proportional to the tonnage of wastes landfilled annually.

CREED e.V.
CReED, Germany focuses on the training of qualified staff for balanced sustainable waste management

There is no appropriate waste management without adequately trained staff.

Cost-intensive aftercare of the Gallenbach household waste landfill, Germany

In the first twenty years after the closure of the Gallenbach landfill in 1991, a sum in the tens of millions of euros had to be spent on surface sealing measures and the capture of landfill gas.

Annual upscaling of methane emission field measurements from two Danish landfills, using empirical emission models K. Kissas*, A. Ibrom, P. Kjeldsen, C. Scheutz

An empirical model was developed and employed to estimate annual methane (CH4) emissions from two Danish landfills (Skellingsted and AV Miljø).

Efficiency of gas collection systems at Danish landfills and implications for regulations Zhenhan Duan, Peter Kjeldsen, Charlotte Scheutz*

This paper presents the gas collection efficiencies of 23 Danish landfills and suggests how these values could be used to regulate landfill methane emissions in Denmark.

Methane emissions from Icelandic landfills - A comparison between measured and modelled emissions C. Scheutz*, A. Kjeld, A.M. Fredenslund

This study compares methane (CH4) emissions from five Icelandic landfills, quantified using tracer gas dispersion to modelled emission rates using the IPCC FOD model.

New Global Methane Pledge (GMP) Waste Pathway

Waste is responsible for roughly 20 percent of global methane emissions from human activities, and dramatically scaling up efforts to reduce these emissions can deliver important health and economic development benefits. Launched today, the GMP Waste Pathway will focus initially on reducing emissions across the solid waste value chain, from upstream sources to downstream disposal sites.

How to support Carbon Reduction and Circularity by Suitable Waste Management Dipl.-Ing. (TU) Werner P. Bauer

In today's world, "decarbonization" seems to be the most important buzzword in environmental and climate policy. It is probably due to the general fascination with "geoengineering" that many first think of carbon capture and storage.

Using satellites to uncover large methane emissions from landfills Joannes D. Maasakkers*, Daniel J. Varon, Aldís Elfarsdóttir†, Jason McKeever, Dylan Jervis, Gourav Mahapatra, Sudhanshu Pandey‡, Alba Lorente, Tobias Borsdorff, Lodewijck R. Foorthuis, Berend J. Schuit, Paul Tol, Tim A. van Kempen, Richard van Hees,

As atmospheric methane concentrations increase at record pace, it is critical to identify individual emission sources with high potential for mitigation.

Innovations in Construction Waste Management: Case of Latvia Tatjana Tambovceva, Valentina Urbane, Janis Ievins

Construction waste generated during the construction, renovation and demolition process occupies huge landfills due to significant volumes.

Situation of the Republic of Paraguay in Urban Solid Waste Management Lima Morra, R.

The Republic of Paraguay, with an estimated total population of 7,250,000 inhabitants and an urban population of 4,200,000 inhabitants by 2022, has one of the lowest indicators for sanitation services in the Americas.

Garbage is piling up on the streets of Kathmandu, Nepal

Since some weeks ago garbage started to be disposed on the streets of Kathmandu causing the stench of this rotting garbage to be unbearable for locals and tourists.

WtERT Germany
WTERT Germany in the Baltic States

On behalf of the German-Baltic Chamber of Commerce in Estonia, Latvia, Lithuania e.V. and financed by the German Federal Ministry for the Environment WtERT Germany was to prepare a strategy paper for sustainable waste management in the Baltics and organize a workshop with clear recommendations and impulses.
