About the company

CWare is dedicated to the sustainability agenda and green transition. We are involved in a number of EU research projects within circular economy related to the built environment and urban greening and resilience.


We can assess green and societal impacts and assist in developing green business models and exploitation strategies.


Our mission is to bring new innovative green ideas into life through collaboration and co-development.


URBAN TREE is a spin-off from CWare and are offering a climate-neutral greening and biodiversity solutions to the urban environment.

We are part of Circle House Lab

Circle House Lab is a continuation of the company developments and collaborations from the project Circle House. With Lejersbo as the developer, Circle House is designed to be the world’s first residential building constructed according to circular principles. The aim of Circle House is to create a circular example that is offered and built on market conditions. The project is expected to be completed in 2021.
Circle House Lab is run by GXN and Responsible Assets, in collaboration with Danish Standard.
Circle House Lab is anchored physically and digitally at BLOXHUB, where knowledge from projects and events can be accessed. The project is supported by: Realdania and the Danish Environmental Protection Agency’s Development and Demonstration Pool (MUDP).


Horizon Europe


The ambition of 100KTREEs is to make cities a better and healthier place to live by encouraging municipalities to plant more trees and to optimise the impact of tree planting. The project will support cities by mapping the existing trees and by showing a solid business case for planting new trees, as well as attracting third party sponsorship to make it happen. We need to plant trees now to allow our children to enjoy their shade in 20 years’ time. 

100KTREEs will develop a mapping and modelling toolbox to optimise the planting of trees and to monitor the health of the trees, based on Copernicus and in-situ data. By assigning monetary value to the key attributes of a tree, e.g. pollution absorption, cooling effect, noise abatement, flood risk reduction and increased biodiversity, a number of business cases will be developed for our two partner cities, Copenhagen and Sofia.  Such business cases will also be used to attract third party financing.  By means of a crowd science app we will engage with citizens and create awareness of the wonders of trees, also extending to improved life quality and mental health impacts.

The project is supported by the Horizon Europe program and is Danish led by CWare Aps and DHI with additional Danish participation by UrbanDigital Aps and EcoTree. Copenhagen and Sofia (Bulgaria) are to be used as pilot cities. 


Horizon Europe


Traditional silo approaches, where stakeholders manage their own data, could be replaced by digital and smart buildings, merging heterogeneous data sources, and placing the stakeholders as the core of these buildings. DigiBUILD will catalyse this much-needed transformation by making use of high-quality data and next generation digital building services, supporting the deployment of EU-wide Framework for a Digital Building Logbook. An inclusive environment for multi-stakeholder knowledge exchange (based on European Bauhaus initiative) will be applied to co-design end-user-oriented services. DigiBUILD will provide an open, interoperable and cloud-based toolbox to transform current ‘silo’ buildings into digital, interoperable and smarter ones, based on consistent and reliable data, supporting better-informed decision-making for performance monitoring & assessment, planning of building infrastructure, policy making and de-risking investments. It will be built on top of existing platforms and common EU initiatives, towards an Energy Efficient Building Data Space, based on standard cloud-data platform frameworks (FIWARE) and Data Space initiatives (GAIA-X and IDSA). On top of this advanced data governance framework, we will create AI-based data analytics and Digital Building Twins based on high-quality data, aiming to facilitate transparency, trust, informed decision-making and information sharing within the built environment and construction sector, which will be deployed across 10 real-world conditions (TRL 8). DigiBUILD will contribute to the uptake of digital technologies in the building sector to better align the EU Member States’ long-term renovation strategies with the EPBD requirements on decarbonisation, and on a path towards a climate-neutral building stock by 2050.


Horizon Europe


The incineration of biomass, municipal solid waste and sewage sludge produces significant quantities of ashes in the EU: approximately 25 million tons annually. These residues have currently no use or they are utilized only in low-value applications. Major problems with the use of incineration residues in the construction, water treatment, and other industries are insufficient public awareness of the safety and environmental acceptability of the final products , the lack of uniform regulations, and readiness of the market to accept incineration residues as a supplementary material. The project AshCycle will demonstrate and implement industry-urban symbioses revolving around the underutilized ashes to reach circular and climate neutral economy in Europe. Pilots and replication demonstrations will be carried out in Denmark, Finland, Belgium, The Netherlands, Croatia, Slovenia, Switzerland, and South Africa. The symbioses will include all major actors from the value chains, namely ash providers, ash beneficiation handlers, concrete and adsorbent product providers, as well as engagement of general public. AshCycle answers unmet socio-economic demands, facilitates emerging ash-based circular products for market entry and to unlocks benefits for society by acceptance of new circular concepts.




CURE synergistically exploits the Copernicus Core Services and develops an umbrella cross-cutting application for urban resilience in DIAS (Data and Information Access Services), consisting of individual cross-cutting applications for climate change adaptation/mitigation, energy and economy, as well as healthy cities and social environments, at several European cities.


NVE Interreg project


By-products for sustainable concrete in the urban environment

URBCON will reduce the high primary raw material consumption and CO2 emissions, that result from the construction and maintenance of the urban built environment (e.g. buildings, pavements, sewer pipes, bridges). The focus is on concrete, being the most used building material. The overall objective is to apply by-products as alternative raw materials for concrete.

Activity 1: Sustain URBCON technology

Activity 2: Sustain the SRM Market Platform

Activity 3. Quantify environmental and economic viability

Activity 4: Roadmap for roll-out of URBCON concept


Marie Curie Innovative Training Network


PhD framework creating a critical mass of experts skilled in innovative alkali-activated material (AAM).

The aim of DuRSAAM is to strengthen the European research area on eco-efficient construction materials and the increased competitiveness of Europe’s construction sector, in applying concrete technology based on alkali-activated materials (AAM) for a more sustainable built environment.




Mineral wool waste back to loop with advanced sorting, pretreatment and alkali activation.

The WOOL2LOOP project aims to close this material loop by introducing novel technology and value chain to CDW sorting, pretreatment, and processing.

The quality of sorted mineral wool is upgraded by comparing and combining the following approaches: pre-demolition audit, robotized demolition and sorting, novel on-site analysis with timegated Raman spectroscopy, and smart demolition practices.




Advanced material solutions towards high efficiency solar energy harvesting.

NewSol develops advanced materials solutions based on innovative storage media and concepts for Thermal Energy Storage (TES) for Concentrated Solar Power (CSP).


FP7 project


Use of eco-friendly materials for a new concept of asphalt pavements for sustainable environments.

To demonstrate and validate an eco-innovative design of asphalt pavements based on the integration of more sustainable materials into its production cycle.

This goal will be achieved by working on two asphalt mixtures’ main components, binders and aggregates. On the binder side, the aim is to replace almost the 100% of the bitumen by greener materials from renewable raw sources, e.g. vegetable oils, by-products of bioethanol production.

On the aggregates’ side, efforts will be made on the valorization of Construction and Demolition Waste and in the use of reclaimed asphalt for asphalt mixtures.
