Circular Measures and Products

BIG Biogas production



Solids from blackwater and organic waste from kitchens and gardens can be used to produce biogas. The generated biogas can be used for cooking or heating. The gas is stored in inflatable and impermeable fabrics. This energy storage can be further used for potential grid injection, or combustion in a natural gas boiler and can support the NZEB or passive house claim to reach full autonomy even in winter months.



Anaerobic biogas digestor

HomeBiogas develops biogas systems. The anaerobic system decomposes waste (kitchen waste, animal manure, and human waste)  and transforms it into renewable biogas for cooking and into liquid bio-fertilizer.

BIO Biobased materials

A bio-based material is a material made from substances derived from living (or once-living) organisms. Using building materials based on natural and renewable sources is more sustainable and circular than materials based on finite and/or carbon intensive exploitation.



Heraklith – Wood wool insulation panels

Heraklith Wood Wool panels are lightweight, easy and time-saving to install, and made mainly with wood certified by the Programme for the Endorsement of Forest Certification (PEFC).



alfaWALL – Prefabricated straw modules

Okambuva is a company that has developed prefabricated straw panels for construction, suitable as load-bearing elements and envelope that meet current energy efficiency standards and are produced with local and nearby resources.


Wooden exterior cladding

Wood building provider that can be used for building houses and/or covering surfaces like floors, ceilings, internal walls, facades, terraces and fences.

> Tarkett

Tarkett Linoleum Flooring

Tarkett Lino flooring is made of renewable and biobased materials like linseed oil, pine rosin, wood and cork flour and jute and is designed to be fully recyclable even after use. Originale is a linoleum flooring protected with Essenza+ (acrylic finish). Elafono is a cork underlay and is designed to give additional sound reduction and comfort underfoot.

BMP Building materials passport


Materials passports contain information about the quality, origins and location of materials and products used in the construction of buildings and other construction objects. All in such a way that owners and/or managers of real estate and infrastructure always have up-to-date information on the financial and circular value, toxicity, demountability and reuse potential of the materials and products applied in their properties.



Digital Building Materials Passport tool

A platform for the registration, organisation, documentation, storage and exchange of data regarding any materials, components and products used by the construction industry at such a high level of detail that the materials consumed in the economy can remain available to future generations, through circularity and the circular economy.

COM Compost production

Kitchen scraps, yard waste and/or stabilised blackwater from anaerobic digestion systems can be used as compost for local gardening, substituting or competing with commercial compost.



Anaerobic digestor

A system for your waste management, energy generation and organic fertilizer needs. Through the biodigestion the bacteria break down organic waste, like food scraps and animal manure, producing biogas. Bacteria in the digester also produce organic, liquid bio-fertilizer. The bio-fertilizer flows freely so you can easily collect and use it on your crops.


Blackwalls Compost Converter

Low-maintenance composter with good capacity. It deals efficiently with all types of food and garden waste. Made from 100 per cent-recycled plastic. Comes with a three-year warranty. It needs to be placed on soil or grass as the relatively small amount of liquid produced during composting drains from the base. Site in partial or full shade.

CWM Circular waste management



Construction and demolition belong to the five priority areas to be tackled in the context of the European circular economy. It is the built environment where the majority of the European waste production originates, in form of construction and demolition waste, wastewater and organic waste. Circular economy principles allow for the implementation and incorporation of waste management into economically viable and sustainable solutions that convert retrofit investments from a liability into an asset.


> ITeC

TCQi – Environmental model management programme

Optimal management of waste at the end of building life cycle. An analysis of maximum recovery and valorization potential of existing materials in buildings (i.e., envelope, facade, etc.) at refurbishment or demolition stages. The solution provides with demolition guides to guarantee safety management of waste streams.


Circular waste management service

CoCircular offers an integral service of circular waste management for developers, construction companies, engineering firms and architecture studios. They also certify the traceability of construction waste until its actual recovery.

DES Desmountable and/or prefabricated products

Circular materials can be used to produce prefabricated, fully reusable buildings. It can be done by designing reusable building components to be produced in automated BIM controlled production processes. Prefab plug & play solutions have proven to be effective to come to a:

  • Reduction of both renovation time on site and costs.
  • Reduction of disturbance for occupants during the renovation works.
  • Quality improvement by better quality control during the production process (then on-site works).



Timber frame prefab panels

Timbeco prefab solutions are designed for the construction or renovation of buildings. They offer a standard solution (Timbeco Modular System) or tailor-made projects. The solutions are based on modularity and can be customized as your needs change.



Prefab timber panels

WEBO produces timber frame elements for residential and non-residential construction projects. Thanks to an automated production process, WEBO is able to assemble timber frame construction elements at the construction site within a minimal lead time.


Straw prefab wall panels

EcoCocon straw wall panels consist of 98% straw and timber. Together with an interior clay plaster, an exterior airtight membrane and a protective layer of wood fibre board, the system is Passivhaus standard certified, achieving the U-value of 0.123 W/m2K. The entire system is vapour-permeable and provides exceptional indoor comfort. The panel types include braced panels, lintels, sills, columns, and inclined gable wall elements. They are made of locally sourced natural materials that do not undergo any chemical treatment during the production process. Precision-cut and prefabricated, panels are designed for quick and easy assembly, only requiring basic carpentry tools.


Prefab wood houses

Prefab wood house builders with the mission to provide sustainable and ecological construction services at competitive prices using the best resources available – skilled specialists, modern technology, and materials safe for the environment and people.

EBP Reusing existing building products an recycled materials

Reusing existing building materials can reduce emissions, but also help to retain the value of buildings over their lifetime and support the local economy.
To increase reuse it is necessary to maximize the amount of valuable materials recovered by increasing the acceptance of Construction and Demolation Waste CDW – based products. E.g. CDW-derived materials can be effectively reintroduced in the production cycles of concrete and timber components with a replacement rate of 50-85 %.


Mat Map

Recycled construction materials wholesaler

MatMap’s philosophy consists of renewing the productive model of the construction sector, making it more sustainable. For this reason, we work to connect professionals who have recovered construction materials, work leftovers, leftover stock or ecological materials, with anyone who wants to apply them to their projects.


Recycled construction materials wholesaler

Rotor Deconstruction is a cooperative based in Brussels, that organises the reuse of construction materials. They dismantle, process and trade salvaged building components. Rotor DC seeks to collaborate with contractors, non-profits and other companies, and to become a central part of a regional ecosystem for large scale reuse of building materials.

LCM Local and/or certified circular materials


It is important to choose certified circular construction materials and products from the different seals available during the design phase that are available as close to the building as possible. The use of certified building circular material will be essential for the improvement of building circularity.


> Cradle to cradle products innovation institute
