Current topics

Within the scope of our newsletters, we regularly inform about innovations in the field of mineral waste management – whether it be a revised regulatory framework, new technologies or new products and services offered by our group of companies. However, some topics that will have an impact over the long term or hold far-reaching relevance for the use of secondary aggregates are briefly summarised again here. If you have any further questions, please do not hesitate to contact us. And we also recommend that you subscribe to our German newsletter or English newsletter, which we send out approx. 4 times a year to inform you about updates to relevant regulations and related amendments or new publications, e.g. the Handbook on secondary aggregates.

Possibilities for the post-tender use of substitute building materials

Construction materials from secondary sources such as recycled aggregates are not always adequately considered in tenders. Time and again, primary building materials are explicitly put out to tender, even though the use of alternative building materials would have been permitted in whole or in part from both a technical and legal point of view. However, there is still room for manoeuvre even after the contract has been awarded.

Dr. Lars Hettich, lawyer and specialist solicitor for public procurement law at the law firm BEITEN BURKHARDT takes up this topic in a specialist article in the magazine Kommunalwirtschaft. Step by step, the possibilities for subsequent material changes in according with the German law are discussed therein.

The magazine Kommunalwirtschaft is the organ of the Verein für Kommunalwirtschaft und Kommunalpolitik e. V. The responsible publisher has agreed to the publication of the corresponding article as a special edition at our request. The German article can be ordered here on the German order page free of charge.

Priority for secondary aggregates in construction: German juris® legal article as special print edition

"There is a need to improve the legal framework for the use of mineral substitute construction materials under waste and procurement law. " This is the conclusion drawn by Gregor Franßen, lawyer at Heinemann & Partner, when asked about the legal framework for the use of secondary aggregates in Germany.

"Although the entire legal framework under waste and procurement law is aimed at promoting the use of recycled building materials, there is a considerable contradiction between, on the one hand, the legal and political claim to promote the avoidance and recycling of mineral waste and, on the other hand, the legal practice, which is characterised by the lack of binding force and enforceability of the requirements under waste and procurement law".

At the same time, if one considers the considerable influence that the public sector has on the utilisation of mineral substitute building materials in public construction measures due to its buying power, in that it decides on whether and how to use mineral substitute building materials by designing its tender documents, there is an urgent need for action to optimise the legal framework.

A positive example here is the Waste Act in Thuringia, which Gregor Franßen discusses in a specialist article in the German juris® PraxisReport. Due to the relevance of the article, we have had it produced as a special print, which we make available free of charge and which you can order via our German order page here.

Road rubble containing tar: ifeu's ecological study supports use as landfill construction material

The ifeu Institute for Energy and Environmental Research in Heidelberg has published a study on the "Ecological approach to the disposal of tar-contaminated road rubble". Commissioned by the BDE - the German Association of Waste Management, Water and Raw Materials Management – the authors Florian Knappe and Joachim Reinhardt compare the life cycle assessments of different alternatives for dealing with road demolition material containing tar, including disposal at landfills, recycling as landfill construction material and thermal treatment.

LfU Bayern: New factsheet on road construction

From 2018, the Free State of Bavaria in Germany will no longer reuse tar-based material on federal and state roads in order to avoid a shift and uncontrolled distribution of PAH-containing material in municipal and private road construction. In 2017, the Bavarian State Office for the Environment (LfU) compiled comprehensive information on the legal background and on the environmental requirements for the technical design and operation of processing plants as well as for the storage and recycling of road demolition in leaflet No. 3.4/1 LfU factsheet collection

Free special publication "Verkehrsblatt" with BMVI regulation for road demolition waste containing tar

The German Federal Ministry of Transport and Digital Infrastructure (BMVI) has changed the regulations for road construction materials containing tar. The General Circular on Road Construction No. 16/15 of the BMVI was published in the "Verkehrsblatt Heft" 22/2015. In it, the Federal Ministry asks that "as soon as possible, but no later than 01.01.2018, the installation of mixtures of construction materials with tar-containing components (recycling classes B and C of the RuVA-StB) in base layers of federal highways are no longer to be permitted".
