The next World Expo will take place from 20 October 2020 to 10 April 2021in Dubai, where the theme will be “Connecting Minds, Creating the Future”.
More than 190 countries will be participating in what will be the first Expo to be held in the Arabic-speaking region. The organisers are expecting over 70% of the visitors to come from overseas.
Koelnmesse GmbH will be organising and running the German Pavilion at Expo 2020 Dubai on behalf of the Federal Ministry for Economic Affairs and Energy. The “German Pavilion Expo 2020 Dubai Consortium”, comprising facts and fiction GmbH (Cologne) and NUSSLI Adunic AG (Hüttwilen, Switzerland), is in charge of concept design, planning and realisation. facts and fiction is responsible for content, exhibition and media design, and the pavilion is being built by NUSSLI Adunic.
UGT is a partner of the consortium and presents itself with its exhibit “Ecoworm” at the exhibition.

The architecture and spatial design come from LAVA – Laboratory for Visionary Architecture (Berlin). The cultural programme, known as Culture Lab, is being put together by Frankfurt-based agency VOSS+FISCHER, working in a consortium with culture and media manager Mike P. Heisel.

UGT is proud to be part of this magnificent event!
Expo 2020 Dubai takes place from 20 October 2020 to 10 April 2021. Over the course of 173 days, the world exhibition will present innovations, share ideas and foster collaboration between Nations to consider the challenges facing today’s world and the ways in which they could be solved. “The World’s greatest Show” presents itself in line with its overarching theme of “Connecting Minds, Creating the Future”.
In Dubai, the focus will be on three sub-themes of major significance for the world in which we live: opportunity, mobility and sustainability. They each present us with a difficult task but they also offer new perspectives on how we can change the way we live our lives.

Expo 2020 will be the first world expo to be held in MENA region and is set to attract the highest ever number of visitors from abroad. The number of visits to Expo 2020 is expected to be as high as 25 million, with around 70% coming from outside the United Arab Emirates. More than 200 countries, international organisations and companies will be represented in Dubai – to ensure a better, sustainable future..
We will keep you in the loop for further details!

Effect of artificial soil compaction in landfill capping systems on anisotropy of air-permeability

Abstract
Soil air permeability is an important parameter which governs the aeration in soils that significantly promotes the root growth of field and grassland species and leads, in turn, to higher levels of evapotranspiration. The German Landfill Directive (2009) requires a rigid or a minimal shrinking capping system that ensures a high evapotranspiration rate to decrease the infiltration rate through the underlying waste body and therefore the leachate generation. This research is focussed on the questions if compacted glacial till can ensure the required rigidity and if and how air permeability is affected by soil compaction.
The objective was to compare air-filled porosity and the direction-dependency of air permeability of a capping soil when assuming rigid and non-rigid conditions considering a shrinkage factor. Intact soil cores were sampled in vertical and horizontal direction in 0.05, 0.2, 0.5, and 0.8 m depths at two profiles of a mineral landfill capping system at the Rastorf landfill in Northern Germany. Desiccation experiments were carried out on differently-compacted soils and soil shrinkage was measured with a 3D laser  triangulation device, while the air permeability was estimated with an air flow meter.
The results indicate that the ‘‘engineered’’ soil structure which was predominately platy due to a layered installation, led to a more anisotropic behaviour and therefore to higher air permeability in horizontal than in vertical direction. The compacted installation of the capping system seems to be effective and observes the statutory required more-or-less rigid system, otherwise, soil shrinkage would lead to vertical cracks and a more pronounced isotropic behaviour.
