Danish Waste Solutions ApS is an independent consulting company offering expert services within the management of waste and resources with particular emphasis on environmental aspects. At the moment, the company consists of three partners, Jiri Hyks, René Møller Rosendal and Ole Hjelmar, all of whom have years of experience with consultancy and management and performance of R&D projects for industry, waste management companies and public authorities.
Our work is based on technical, applied science coupled with up-to-date-knowledge of the technical and regulatory development within the above mentioned areas in Denmark and abroad. The work is supported by the results of R&D performed by ourselves and others. We have close contacts to a broad network of scientific institutions and companies with whom we co-operate when required to ensure optimum solutions to specific projects.
We participate in a number of networks and organisations:
We are ready to solve exactly your problem. We have experience within:
Planning and execution of sampling of all types of waste, including slag, fly ash, construction and demolition waste, shredder waste, contaminated soil, other industrial and municipal waste types and byproducts, etc.
Planning, execution and interpretation of results from leaching tests for both inorganic and organic substances (waste, residues, soil, construction products). We help you to select proper leaching test, ensure the best quality and price and explain to you what the results mean.
Planning and execution of various experiments, including pilot-scale trials, aimed at optimisation of both environmental and technical parameters as well as identification of different options for recycling, recovery, treatment and landfilling of waste and contaminated soil.
Planning and execution of field studies aimed at assessment of environmental impacts from landfills including planning and implementation of monitoring of leachate and groundwater, and assessment of potential recycling of resources from deposited waste (i.e. Landfill Mining).
Assessment of the duration and development of strategies for minimisation of the aftercare period at landfills.
We help with e.g. Biocover solutions (measurements,
calculations, system set-up); Test pumping of landfill gas;
Extraction of landfill gas (low-tech solutions); Set-up of
gas collection systems and engines.
Assessment and calculation of the environmental risks, environmental impacts and resource optimisation in the short and long term for different forms of recovery and/or utilisation, storage and disposal of wastes, residues, soil and construction products. In addition, concept and projecting of leachate recirculation scenarios.
Classification of waste materials (and contaminated soil) as non-hazardous or hazardous waste in accordance with the new classification rules based on CLP regulation, which came into force on 1 June, 2015.
Preparation of technical background materials for
modification and/or development of guidelines and
regulations for recycling, utilisation, handling and
disposal of wastes, residues and contaminated soil in order
to protect the environment and optimisation of resources.
Geochemical modelling to understand / explain the results of leaching from different materials.
Consultancy relating to compliance with environmental criteria in Danish legislation and EU legislation on waste management.

Danish Waste Solutions ApS which was formed in February 2015 consists of three partners, Jiri Hyks, René Møller Rosendal and Ole Hjelmar, all of whom have years of experience with consultancy and R&D together with implementation of projects for industrial enterprises, waste management companies and public authorities. In addition, we have a broad network of scientific institutions and co-operation partners upon whom we can draw to optimise specific solutions.
We have work experience from projects carried out in Denmark, Belgium, Bermuda, Canada, Faroe Islands, Finland, Germany, Greenland, Hungary, Iceland, India, Ireland, Jersey (CI), Mexico, The Netherlands, Norway, Poland, Russia, Singapore, South Africa, Sweden, Taiwan, United Kingdom, and the United States.
Jiri is a chemical engineer (UCT Prague, Czech Republic) and he received his PhD from DTU Environment in 2008. Through his work at the Technical University of Denmark (2004-2010) and later as an consultant on DHI (2010-2015), he has led and participated in many Danish and international R&D projects and consultancy tasks related to representative sampling, characterisation, testing, processing, recovery and disposal of different types of waste including residues from waste-to-energy systems, mining waste, phosphogypsum, shredder waste, waste from municipal recycling stations, various aggregates (bottom ash, construction and demolition waste, cast iron, steel slag, etc.), construction products, and contaminated soil and sludge.
Jiri participates in the development, validation and standardization of leaching tests as well as implementation and interpretation of leaching tests for, among other things, obtaining End-of-Waste status of bottom ash from waste incineration, geochemical modeling of leaching of metals from contaminated soil or industrial waste. Moreover, Jiri is familiar with material flow analysis (MFA) and is interested in life cycle assessment (LCA) of waste systems and in landfill mining.
Jiri is the author/co-author of 13 scientific articles.
René is a MSc. in geography and Technological and Socio-economic Planning (Tek-Sam) from the University of Roskilde, 2003. Through his work at RenoSam (2003-2004), Copenhagen County - soil and groundwater division (2004), RenoSam (2004-2013) and more recently as a special advisor in Danish Waste Association 2013-2015). He has been responsible for the area of landfilling of waste, contaminated soil and construction and demolition waste with the purpose to represent and maintain the members interests in the field, including counseling and guiding the members. He has been running the ERISDA secretary, working group on landfill, C&D network in Danish Waste Association. Through the years he has led and developed several projects on Landfill Mining, biocover, utilization of landfill gas, shredder waste, mapping of the landfill capacity in Denmark, Taxation and re-use of contaminated soil, characterisation of waste, and Verification and extended control of nonhazardous waste prior to landfilling at Glatved Landfill, Reno Djurs investigation of the potential health risk of handling asbestos and investigation of contaminants in C&D from recycling stations and completed several EU-tenders for municipalities and waste companies.
René has participated in several working groups and contribruted to the National Ressource Strategy and since 2010 developed the Danish EPA´s annual Benchmark report on landfill. Moreover, René has a great knowledge about the municipal waste sector and daily operation of modern landfills and how to optimize this in order to minimize the environmental impact of the surroundings and the working environment as much as possible.

He has participated in the development of and has as an advisor and consultant provided technical support to the development and national implementation of the EU Landfill Directive Denmark and the EU Mining Waste Directive. He is involved in the implementation of environmental considerations in the Construction Products Regulation and in the development and robustness validation of related leaching tests. He is chairman of one of the EU Commission working group set up to develop criteria for acceptance of monolithic waste at landfills. He has developed, constructed and interpreted leaching tests and methods for characterisation of construction and demolition waste, and he has (for the European Commission (JRC) developed proposals for methodologies for obtaining End-of-Waste Status for waste-based aggregates. Ole is closely following and participating actively in discussions concerning the ongoing changes of the EU legislation on classification of waste as hazardous or non-hazardous.
Ole is the author and co-author of numerous reports on studies funded by the Danish Environmental Protection Agency and several reports published by the EU Commission. He has contributed to six text books and is the author / co-author of 18 scientific articles and more than 100 international conference papers.
