Stimulus Project Brightlands Chemelot Campus

Het project Circulaire en modulaire woningen voor de sociale woningbouw heeft als
doel door regionale ketensamenwerking een marktklare, economisch haalbare,
circulaire, flexibele en aantrekkelijke oplossing te realiseren voor de uitdagingen in
de sociale woningbouw.

De basis van het nieuwe woonconcept is de modulaire circulaire rijtjeswoning
geschikt te maken voor de sociale woningbouw. De woning onderscheidt zich
doordat hij: (1) demontabel is, waardoor haar materialen na gebruik teruggewonnen
en hergebruikt kunnen worden; (2) gebouwd wordt met duurzame (biobased
(bermgras) en circulaire) materialen; (3) gebouwd wordt middels een stikstofloze
modulaire bouwmethode; (4) betaalbaar en onderhoudsarm is; (5) een lange
levensduur heeft en geschikt is voor tijdelijke en permanente woningbouw; (6)
comfortabel, aantrekkelijk en snel beschikbaar is; en (7) energiezuinig en
zelfvoorzienend is (NOM woning energiebesparende ramen en isolatie.

Om impact te kunnen maken is het belangrijk om multidisciplinair en met de hele
keten samen te werken en aan te sluiten bij de wensen van de eindgebruikers.

Hiervoor bestaat het gevormde consortium, onder leiding van de Brightlands
Chemelot Campus, uit verschillende ketenpartners, van (MKB) bedrijfsleven tot
kennisinstelling, van techniekontwikkelaars tot woningcorporatie en van
opleidingscentrum tot marktpartij. Daarnaast worden bewonerspanels/starters via
woningcorporatie betrokken bij dit project, wordt middels open innovatie ingezet op
het inzetten van circulaire innovaties van Limburgs MKB en startups in de
demonstatiewoningen, en zijn er experts zoals de Rabobank op het gebied van
financiering (zie partneromschrijving en LOI (Bijlage A)) betrokken bij relevante
vraagstukken zoals het financieringsmodel en opschaling. De Chemelot Campus
ondersteund de ontwikkelaars in de ontwikkeling en het testen van de nieuwe
materialen en managed het project.

Block Materials richt zich, iov Stichting Maeconomy, de spil in het web voor het
ontwikkelen van het woonconcept. In het bijzonder op het verdienmodel van het
concept. Dit verdienmodel waarborgt circulair gebruik van materialen. Materialen
behouden namelijk waarde, waardoor ze na gebruik door de producenten
teruggenomen worden en hergebruikt worden voor dezelfde toepassingen. Het
behoudt van waarde maakt dat de kosten voor de gebruiker lager zijn.
Om de woning financieel nog toegankelijker te maken wordt er gezocht naar een
toegankelijke manier van financieren. De combinatie van een circulair verdienmodel
en toegankelijk financieringsmodel maakt de hoge kwaliteit van de circulaire woning
beschikbaar voor een lage prijs.

Het Consortium bestaat uit Chemelot Campus, CHILL, CUBE Homes, Stichting
Maeconomy, ECOR, Mosa Tiles, TNO/BMC, Bouwmensen, Zuyd Hogeschool,

Stimulus Project Brightlands Chemelot Campus

The Circular and modular homes for social housing project aims to realize a market-
ready, economically feasible, circular, flexible and attractive solution to the challenges
in social housing through regional chain collaboration.

The basis of the new living concept is to make the modular circular terraced house
suitable for social housing. The house is distinguished by the fact that it: (1) can be
dismantled, so that its materials can be recovered and reused after use; (2) is built
with sustainable (biobased (roadside grass) and circular) materials; (3) is built using a
nitrogen-free modular construction method; (4) is affordable and low-maintenance;
(5) has a long lifespan and is suitable for temporary and permanent housing; (6) is
comfortable, attractive and quickly available; and (7) is energy efficient and self-
sufficient (NOM home energy-saving windows and insulation.

In order to make an impact, it is important to work multidisciplinary and with the entire
chain and to respond to the wishes of the end users.

For this purpose, the consortium formed, led by the Brightlands Chemelot Campus,
consists of various chain partners, from (SME) businesses to knowledge institutions,
from technology developers to housing associations and from training centers to
market parties. In addition, resident panels/starters are involved in this project
through a housing association, open innovation is used to deploy circular innovations
from Limburg SMEs and startups in the demonstration homes, and there are experts
such as Rabobank in the field of financing (see partner description and LOI (
Appendix A)) involved in relevant issues such as the financing model and scaling up.
The Chemelot Campus supports the developers in the development and testing of
the new materials and manages the project.

Block Materials, in collaboration with the Maeconomy Foundation, is the hub in the
web for developing the living concept. In particular on the revenue model of the
concept. This revenue model guarantees circular use of materials. Materials retain
value, meaning they can be taken back by manufacturers after use and reused for
the same applications. Retaining value means lower costs for the user.

To make the home even more financially accessible, an accessible method of
financing is being sought. The combination of a circular revenue model and
accessible financing model makes the high quality of the circular home available for a
low price.

The Consortium consists of Chemelot Campus, CHILL, CUBE Homes, Stichting
Maeconomy, ECOR, Mosa Tiles, TNO/BMC, Bouwmensen, Zuyd Hogeschool,

SUM4RE

Het intensieve gebruik van grondstoffen in de bouwsector, dat ruim 40% van de uitstoot van broeikasgassen (BKG) vertegenwoordigt, staat onder druk door de schaarste van deze materialen, haar economische waarde en ecologische voetafdruk. Stedelijke mijnbouw (Urban Mining), bestaande uit het terugwinnen van materialen en elementen uit elke vorm van antropogene ( alles wat door de mens is teweeg gebracht, voorraden, inclusief gebouwen of infrastructuur, kunnen als alternatief worden geformuleerd voor de uitputting van natuurlijke hulpbronnen.

Omdat het koolstofarm maken van alle sectoren nodig is om tegen 2050 een koolstofneutrale EU en de tussentijdse doelstelling voor de reductie van broeikasgasemissies voor 2030 van 55%, te bereiken, ondersteunt circulariteit deze doelen van duurzaamheid. Circulariteit kan dan ook worden gezien als een van de voorwaarden en belangrijkste oplossingen voor transformatie naar duurzaam gebouwde woonomgeving.

Bouw- en sloopafval (CDW), exclusief mijnbouwafval, vertegenwoordigt de grootste afvalstroom in de EU in termen van massa. In 2020 bedroeg het totaalbedrag van de in de EU27 geproduceerde CDW bedroeg 330 Mton (exclusief uitgegraven grond, baggerspecie) en groeit op basis van gegevens van Eurostat de CDW-productie verder. Deze massa heeft betrekking op afval gegenereerd tijdens de verschillende bouwfasen (bouw, renovatie en sloop), waaruit de sloop fase domineert.
Hoewel het terugwinningspercentage van bouwafval in de EU hoog is, wordt het afval voornamelijk in laagwaardige toepassingen, zoals wegenbouw, hergebruikt. Om de verschillende obstakels voor circulariteit te overwinnen die bij belanghebbenden naar voren komen in de waardeketen moet speciale aandacht worden besteed aan het gemakkelijk beschikbaar maken van relevante gegevens voor besluitvorming voor nieuwe mensen en opkomende gestandaardiseerde EU digitale instrumenten, zoals afvalaudits, digitale materiaalpaspoorten en digitale producten, digitale bouwlogboeken en EU-protocollen voor bouw- en sloopafvalbeheer.

In lijn met het EU DBL-initiatief (Figuur 1) streeft SUM4Re naar een integrale aanpak voor het creëren van materiaalbanken uit de gebouwde omgeving door urban mining en technologieën voor geautomatiseerde data-acquisitie te combineren ([1] met identificatie en modellering ([2]. Een paradigmaverschuiving van conventioneel BIM naar een open circulair Begeleide BIM wordt voorgesteld om nieuwe bedrijfsmodellen op secundaire materialen te ondersteunen en daarom [3]circulariteit te realiseren. De daadwerkelijke bijdragen van SUM4Re zullen bestaan uit een reeks meetbare resultaten die zullen worden geïmplementeerd gevalideerd via 15 Use Cases (UC).

Summary SUM4RE

The intense use of raw materials in the construction sector, which represents more than 40% of Greenhouse Gas (GHG) emissions when accounting for the first use of materials, is jeopardized by their scarcity, economic value, and environmental footprint. Urban mining, consisting in the reclamation of materials and elements from any kind of anthropogenic stocks, including buildings or infrastructures, can be articulated as an alternative to depleting natural resources. As the decarbonisation of all sectors is needed to achieve a carbon neutral EU by 2050.

and the intermediate GHG emission reduction target for 2030 is set at 55%4, circularity is broadly supportive of sustainability and may be seen as one of the conditions and main solutions for transformation to a sustainable built environment. Construction and demolition waste (CDW) excluding mining wastes represents the largest waste stream in the EU in terms of mass.

Based on Eurostat data, CDW generation is growing. In 2020, the total amount of CDW produced in EU27 was 330 Mt (excluding excavated soil, dredging spoils). This number covers waste generated during the different building phases (construction, renovation, and demolition), out of which the demolition phase is dominating. Although the recovery rate of CDW in EU is high, the waste is mainly used in low-grade applications like earth construction.
To overcome the different obstacles to circularity that emerge from stakeholders in the value chain, a special focus must be put on making relevant data for decision-making easily available to new and upcoming standardized digital instruments, such as Waste Audits, Digital Material Passports, Digital Product Passports, Digital Building Logbooks or EU Construction and Demolition Waste Management Protocols.

Aligned to the EU DBL initiative (Figure 1), SUM4Re aims to deliver an integral approach to create materials banks from the built environment by combining urban mining and technologies for automated data acquisition ([1] identification) and modelling ([2] analysis). A paradigm shift from conventional BIM towards an open circular guided BIM is proposed to support new business models on secondary materials and therefore to [3] realise circularity. The actual contributions of SUM4Re will be a set of measurable results that will be implemented and validated through 15 Use Cases (UC).

CIRCULAR CRAFT CENTERS

Based on its work in projects and for the Regional Government, Block Materials designs initial notes, business cases and further applications of Circular Craft Centers in municipalities. These Craft Centers are among the national spearheads of a Circular Economy and also receive finances from the government for implementation and daily operational matters. If you would like to get started with a Circular Craft Center, please contact us.

REGIONAL CIRCULAR ECONOMY

Block Materials has carried out a number of studies for the Parkstad Limburg Region for the further development of the Regional Circular Economy. The three documents she produced: a. “Building blocks for Circular Construction and Demolition”, b. “Transformation of the Built Environment and Circular Demolition” and c. Implementation of Digital Deconstruction in Parkstad Limburg will set up the development of a Circular Construction and Demolition Implementation Program in a Region. This blueprint for the Parkstad Limburg region can be applied in the same way in several regions.

CO2 MODULE

Any material that is reused no longer needs to be produced. This also means that CO2 during the production of a material is prevented through this reuse. Block Materials has developed a module within the Cirdax application that makes various environmental calculations. Including the CO2 saved as a result of using secondary materials. The Co2 module uses the data of materials in a building as a basis for the calculations. For the “embodied Co2” per material, the University of Bath’s ICE database is the central starting point. The calculation options with the Co2 module are expanded to a wider range of desired indicators, such as MKI, MPG, or elements from Breeam, Gro, Level(s) and Totem for the Belgian market. Partly to support specific target groups, such as architects.

BLOCKCHAIN TECHNOLOGY

Block Materials unites the application of blockchain technology with materials in a building. Based on an inventory of materials in a building, Block Materials adds a property right to the material passport of a material based on the #hash. A right of ownership that can also be checked through verification using blockchain technology, thus guaranteeing this right of ownership. Based on this ownership right per material, this material can then be traded, the ownership of the material can be tracked over time, it is possible to enforce liability for future delivery, or the ownership right can be linked to other rights, such as emission rights on the production or reuse of materials. Blockchain technology replaces the role of notaries and appraisers in this regard and results in completely different transaction costs on materials than were previously the case. Block Materials studies all costs and benefits that come to light as a result of this innovation in the various projects in which it works.

MANUALS

Knowledge of the Circular Demolition Process is one of the building blocks of a local circular economy. In the context of the Sustainable Innovation Scheme of Parkstad Limburg and the Digital Deconstruction project, Block Materials has developed a Circular Demolition Handbook that can also be consulted via this link. The manual takes the daily practice of a real estate owner as a starting point, with the central question being classic or sustainable demolition. The manual presents the process of sustainable demolition using 12 steps. The decision to demolish conventionally or sustainably is central, with one half of the manual focusing on the preparation of this decision, and the other half continuing with the decision to demolish sustainably and what to do next. The book works with the central methodology of Blockmaterials in which the trade-off between more value from materials versus carrying out inventories, repairs, refurbishment, etc. follows the common thread. The book contains many practical examples, tools and suggestions on how to tackle sustainable demolition. She does this for each step in the described process.

DEMOLITION PORTAL

On the demolition portal you can find all products that are made for companies and organizations that (want to) get started with Circular Construction and Demolition. This concerns access to our instruments, such as Cirdax and the various Manuals, as well as Education modules for the Demolition Industry. Via the Demolition Portal you also have access to the Sustainable Demolition Calculation Tool, with which you can calculate in advance whether making a material inventory is effective for you. Based on a number of characteristics of a building, she calculates the additional costs of sustainable demolition, and also immediately indicates what the additional revenues are, because the value of the inventoried materials increases due to the work. You can also order an inventory afterwards. You can access the Demolition Portal here.

CIRCULAR AND MODULAR BUILDINGS FOR SOCIAL HOUSING

Data about buildings and materials are an important basis for a different construction process. In the OP-Zuyd project Circular and Modular Homes for Social Housing, Block Materials provides building and material passports for the desired demonstration homes. Based on these passports and the ownership rights to parts of the home, we investigate alternative forms of financing the building, the parts of the building, as well as the size and method of financing by the (future) owner of this home. In this way we contribute to the combination of efficient use of materials, efficient financing and affordable housing. The program runs from 2023 to 2026.

COSTS

In the European research program CircularB (part of the COST network), Block Materials investigates how a holistic and integrated analysis of the reuse of materials in buildings can be given shape. Block Materials provides the project with both legal and economic foundations for this challenge, as well as educational models in which employees can be trained in the future. The program runs from 2022 to 2026.

DIGITAL HUB

The Circular Hubs project investigates the redesign of logistics flows of construction waste in the Parkstad Limburg region as a result of higher values of secondary construction materials in economic traffic. After all, if materials have become more valuable through inventory, repair and/or refurbishment, they can be sold in a different way than is currently the case. This requires research into the retail structure of such materials, or a different organization of the sorting, cleaning and processing process. Block Materials is collaborating with Bouwkringloop and Rd4 on this project. The project also serves as assistance for the Circular Craft Places project.

DEMOBLOG

Block Materials is working in the European Demo-Blog project in collaboration with partners ReUseMaterials, VITO and Leap Forward on an Interactive Marketplace for Architects in Belgium. After all, if verified secondary materials, as made visible with the help of the Cirdax database and blockchain registrations, also find their way into new applications, these materials must be on the radar of architects, project developers and construction companies that use them. wish to use materials. For the latter, the availability and quality of the materials must be transparent for both suppliers and buyers of materials. Both sides of the transaction of secondary materials will also have to match each other, so that payment, logistics, as well as repair and refurbishment of the materials can be organized. The project runs from 2022 to 2026. Block Materials wants to put the project on the market in a first version in 2024.

GROWTH FUND APPLICATION

The core of the instruments that Block Materials develops lies in the possibility of reducing information differences (market failure) about the quality and availability of materials in buildings for the purpose of connecting supply and demand in circular processes. This application of George Akerlof’s The Theory of Lemons to the world of buildings not only requires the large-scale availability of Building Passports for innovation in construction, but also shows that Building Passports cannot simply be created. They form a so-called Collective Good, for which government intervention in the financing of such a “digital highway” is desirable. Block Materials is working within the European Center for Circular Construction and Transformation consortium on the financing of this National Infrastructure by compiling an application for it with the National Growth Fund. Partners who can make a substantial contribution to real estate objects to be digitized can register for a place in our consortium.

Digital Deconstruction

In the period 2019-2023, Block Materials participated in the European Digital Deconstruction project. The aim of the project was to implement new digital instruments for the demolition or dismantling of materials in buildings. With partners, Block Materials has succeeded in implementing the instruments 3D scan, Releasability, Digital Materials Database and Blockchain as Property Right. The last two instruments are made by Block Materials and were built within the Cirdax environment of sister company ReUseMaterials. Based on this infrastructure, Block Materials continues to build solutions for Circular Construction and Demolition in various regions in Europe.

BLOCKCHAIN BOOK

Block Materials’ way of working has a robust basis in the scientific principles of Law and Economics. The application of Blockchain technology within this methodological framework ensures that every material in a building has a well-defined ownership right. This combination of real estate, property rights and new technology has been elaborated on for all facets of innovation related to the reuse of materials in the book Flexible Real Estate with Blockchain.
