One more new project at LGI: HOUSEFUL. This project will literally make your head spin because it aims at full circularity in residential buildings!
Coordinated by LEITAT, this project of 16 partners will last for 4 years and will launch 12 solutions, that are either technical or methodological.
These solutions will be demonstrated during the refurbishment of 4 buildings, 2 near Barcelona – Spain, and 2 in Vienna, with 3 out 4 being on social housing.
Solution #1 – A methodology to evaluate the circularity degree of buildings
Solution #2 – A methodology to co-create, with all stakeholders of the building life-cycle, new business opportunities in tune with the principles of circular economy
Solution #3 – Materials passports: specifying all construction materials of a building, to prepare their recycling
Solution #4 – Databases of local sustainable construction materials
Solution #5 – A nature-based solution to recycle grey and rain waters
Solution #6 – A nature-based solution to recycle liquid part of blackwater
Solutions #7 – Anaerobic Membrane Reactor (AnMBR) and dry Anaerobic Digestion (dAD) tech for bios gas production. Complemented by gas cleaning tech.
Solution #8 – Compost tech to receive the digestate from solution #7
Solution #9 – Procedures for safe disassembly and efficient recycling of construction & demolition waste
Solution #10 – Active and passive tech for energy efficiency
Solution #11 – Pay per use business models
Solution #12 – An online platform to evaluate the circularity of buildings and recommend improvements, backed by HOUSEFUL solutions
- A 30% reduction of construction & demolition waste usually destined to landfills
- Energy efficiency gains of 30%
- Recycling of 50% of biowaste from the kitchen
- Recycling of >90% of each rainwater, greywater and blackwater stream for reuse in toilets flushing, irrigation, and biogas production
- Production of 0.55kg of compost per kg digestate produced from biowaste and blackwater
LGI will carry out the Life Cycle Cost assessment of the refurbishments and recommend the best commercialization strategies for the marketable results of the project.
