Projects and Literature
Our main research topic is the CO2-reduced circular economy of mineral building materials. Basic solutions found within the framework of the Helmholtz research programs are to be proven in practice and must be scientifically, technically and economically developed to higher technology levels. To this end, we conduct joint research projects with partners from universities and industry, which are supported by various funding bodies.
Helmholtz Research Program
Research program “Materials and Technologies for the Energy Transition” (MTET)
Within topic 5, “Resource and Energy Efficiency” we address crucial technology gaps in recycling of building materials.
Research program “Energy System Design” (ESD)
Within Topic 2.1 “Digitalization and Systems Technology for Flexibility Solutions” we focus on the integration of decentralized cement processing technologies in a decarbonized energy system.

Repost: Autoclaved Aerated Concrete
Recycling cluster Autoclaved aerated concrete (AAC): Optimizing demolition and separation of post use AAC and new routes for circular use of AAC
Project duration 01.06.2019 – 31.12.2022
Abstract
The upcoming end of buildings life time within the next years will lead to increasing amounts of post use AAC material from demolition. The Repost project deals with ways of reusing such material batches within the production of new AAC to avoid landfilling and save primary resources.

R-Zement Pilot Plant
R-Zement: low CO2 production of di calcium silicate clinker from recycled construction material
Project duration 01.04.2021 – 30.06.2025
Abstract
R-Zement project aims at a pilot plant to establish a decentralized clinker production at a 10t/h scale. The newly found process generates di calcium silicate clinker (belite clinker) at a temperature of 1000°C. At the pilot plant level the rotary kiln will be electrically heated.
An advisory board with members from Baden-Württemberg administration, industrial associations and companies is set up to guide the project.

Innopool Energy Transition and Circular Economy (EuK)
Innovation pool project 1: Energy transition and circular economy: Decarbonation and flexibilization of energy intensive recycling processes
Project duration 01.01.2021 – 31.12.2023
Abstract
Using thermochemical recycling of waste concrete as an example to simulated implications on mass and energy cycles. What needs to be considered to maintain stable power grids and economic production with increasing amounts of renewables? What is the impact of decentral but energy intensive processes?

Holiscon: Holistic Concrete
Feasibility study for holistic concrete recycling in in Baden-Württemberg
Project duration 01.01.2022 – 31.12.2022
Abstract
To evaluate recycling options for concrete in Baden-Württemberg a feasibility study is based on available data. The study should be amended by recommended actions where on going changes like concrete mixture optimization, new standards, new technologies in general are taken into account.

Ultraefficiency Demonstrator
Ultraefficiency demonstrator for decentralized processes
Project duration 01.05.2021 – 31.12.2022
Abstract
This feasibility study deals with enhancing the circulation of materials, e.g. the demolition and material recycling of external thermal insulation composite systems (ETICS) in construction. The two main fractions, organic vs. inorganic, proceed to different value chains with chemical intermediates and mineral constructions materials as products. Ideally, a complete recycling is to be achieved and will be evaluated.

Urban: low CO2 Concrete
Low CO2 concrete by upcycling wastes from demolition
Project duration 01.11.2022 – 31.10.2025
Abstract
The aim of the project is the manufacturing of high quality and sustainable concretes with partial substitution of components by recycling products (RC) instead of standard cements and aggregates. Separately or in parallel substitution shall be achieved with
- low temperature belite clinker (KIT process) added to OPC based cements and
- mechanically prepared concrete fines.
A final test in the production of precast concrete parts will be based on the adapted clinker process, mix design and ratios, sulfate carrier and additives adjustment.
