The Environmental Science and Engineering Group (ESEG)

Our research has been focused on water/wastewater/stormwater management, solid waste management, and contaminated soil remediation with focus on phyto-techniques, and environmental economics and also sustainable actions towards the circular economy such as landfill mining and harbour mining.

Our research 

Our research is often conducted through close collaboration with industries, companies and other partners outside academia. The aim is to move our society towards sustainable development and an environment that does not pose any negative effect on ecological status and public health. We do research in different scales, such as laboratory, pilot and full scale since it is important to consider real conditions to achieve adequate results.

We are member of The Baltic Sea Challenge

Wastewater treatment

A healthy environment for all people requires a holistic approach to the management of different types of water (stormwater, rain water, industrial and domestic wastewaters) and solid waste. Throughout the course of our research we have been out in the field taking samples and actually trying to solve the problems on site. There are still industries that produce low volumes of highly contaminated waters that municipal wastewater treatment plants cannot handle. We have worked in the past years towards the development of low-cost non-conventional treatment systems to tackle such types of waters such as the use of anaerobic-intermittent aeration processes, wetlands, and sorption with wood-based sorbents such as sawdust and fly ashes. We have also combined these processes with more advanced solutions such as ozonation, photolysis using UV energy and fenton reactions.

Eco-toxicological studies

Our research group has been carrying out a number of toxicity studies with different environmental matrixes and also test organisms in order to evaluate the effects of contaminated soils and waters and also to evaluate the effectiveness of treatment systems. Usually treatment systems are evaluated based on physico-chemical parameters but our group has learned that toxicity studies are a considerable adequate way of understanding treatment of contaminated waters and soils.

Phytoremediation of petroleum hydrocarbons and metals contaminated soil

Over the past few decades, the widespread exportation and consumption of crude oil and metals have led to massive release of these toxic compounds in the environment. Our research group has been studying on laboratory, greenhouse and pilot scale the use of different types of plants-microorganisms to clean up soil contaminated by petroleum hydrocarbons and metals. Phytoremediation studies have been done in cooperation with Rio de Janeiro State University, Montreal University and Kalmarsundsregionens Renhållare - KSRR.

Solid waste management

Waste management is regarded as a basic human need and one of the most important rights. Managing all types of waste in an adequate manner is a global challenge due to considerable population growth (currently 7 billion and expected to increase to more than 9 or 10 billion by the end of this century). According to the World Bank the current global waste generation is 1.3 billion tons and is expected to double within the next 10 years. Waste management is defined as the collection, transportation, treatment/processing, recycling/recovery and disposal of different types of wastes (municipal and industrial) in a proper way.

ESEG group has been working with the concept that all types of waste must be considered as valuable resources either as materials or energy. We have been participating in international network and research projects for landfill mining, which has been considering closed landfills as mines with valuable material and energy for recovery.

ESEG group has also worked with waste disposal techniques and potential air emissions from waste disposal/processing technologies, such baling techniques. The negative effects posed by spontaneous fires in waste disposal areas have been also focused by ESEG in the last years.

Solid waste management

Environmental collaboration

The complexity of environmental problems often requires that many parts of society collaborate. Such collaboration aims to provide solutions that are viable for all partners. Environmental scientists at university can collaborate with industries, companies, public sector, civil sector and other participants in society. This has been less studied in practice however. To remedy this, the research group has had a sociologist working inside the group since 2011. Joacim Rosenlund has performed interactive research with the aim to find out more about such collaboration, which has sometimes been called: triple helix, quadruple helix, mode 3 and more. Making collaboration work better in practice would in the long run benefit all environmental research projects that have any interaction with sectors outside of university.

The "Urban Waste" project

This H2020 project, developed by Consulta Europa on behalf of the Government of Canary Islands, will elaborate strategies for waste management in touristic cities.
From 6th till 8th of June a Kick off meeting of the URBAN-WASTE project took place in Tenerife. 27 partners from 13 countries just started a 3 years collaboration so as to achieve the objective of this project: reduce waste production in touristic cities. Urban Innovative Actions (UIA) is an Initiative of the European Commission that provides urban areas throughout Europe with resources to test new and unproven solutions to address urban challenges. Based on article 8 of ERDF, the Initiative has a total ERDF budget of EUR 372 million for 2014-2020.
The URBAN-WASTE project will develop eco-innovative and gender-sensitive waste prevention and management strategies in cities with high levels of tourism in order to reduce the urban waste production and improve municipal waste management. These strategies will facilitate the reintroduction of waste as a resource into the urban metabolism flows and address waste management, risk prevention and land-use as an integral part of urban development. Stay tuned to follow our next steps #UrbanWasteEU
