Turning rubble into socioeconomic development opportunity for vulnerable communities around the world, creating new products and services.


Summary / Résumé

The urban centers account for about 70% of greenhouse gas emissions. The buildings and road systems use 60% of the electric energy, 40% of the natural resources and generate 40% of the waste. On the other hand, the civil construction sector, based on the research carried out for the Lima-Paris Action Plan (LPAA), generates about 30% of carbon dioxide (CO²) emissions, but if new technologies and processes are implemented, more efficient and less damaging industry, it is possible to reduce these effects over the next 30 years. In developing countries, the poorest people lack innovative solutions for housing, to become resilient to climate change, avoiding problems caused by rains, such as landslides and floods. In Brazil, construction produces 122,262 tons of waste per day and accounts for 61% of all garbage generated in urban areas, according to ABRELPE - Brazilian Association of Public Cleaning and Special Waste Companies. Of these 70% of the waste produced by the construction industry comes from small works, carried out informally and without technical guidance by low income people who do not have access to the technical guidance of Architects and Engineers. If the construction sector is not modernized to reduce its impact on the environment, it will hamper the socioeconomic development of the poor, making housing more expensive, unhealthy and energy inefficient. It calls for viable strategies that instill these populations into the process of change, saving natural resources and securing income for these communities. To achieve this, the Project proposes the creation of an online platform for waste management coming from works carried out by low-income people, in partnership with startups and social businesses that offer technical assistance services at affordable and / or free prices , aiming at reducing waste of water, energy and elimination of waste and debris. And creation of a small ecological brick factories in vulnerable communities.

What actions do you propose? / Quelles actions proposez-vous?

• Creation of the Virtual Bank of Construction Material - Construction Marketplace

The creation of a participatory solid waste management web platform, where consumers and construction professionals can use to give a correct destination for the waste of their constructions and reforms, formal and informal, generating reports of environmental impact and at the same time having the possibility of increasing their income, negotiating recyclable waste, leftover building materials and furniture they no longer want. On this platform, this surplus of registered building material can be exchanged for others, sold or donated for later use in renovations or constructions for housing of social interest; already the non-reusable waste, will have the correct destination for recycling, in the factories of ecological bricks, avoiding to go to landfills. Population growth and the consequent demand for infrastructure and housing are the main drivers of this equation for more use of natural resources and generation of greenhouse gases. Faced with this reality, it is evident the need to mobilize and sensitize the government and society on the problem of irregular disposal of construction waste, offering a sustainable and economically viable solution for the construction industry.


• Low Income Architecture and Urbanization Technical Assistance Network

In Salvador, Bahia, Brazil, as in many Brazilian cities, low-income communities suffer floods and landslides every year during rainy season. In 2017, CODESAL - Civil Defense of Salvador, recorded about 600 landslide risk areas, occupied by informal housing. This scenario could be different if this population had access to secure land and access to Architecture and Engineering professionals. In order to facilitate this access, we intend to create a network of public institutions, NGOs, startups, social businesses and freelancers who are willing to offer services at affordable or free prices. Through the virtual platform and by popularization in popular neighborhoods, we will inform the people where they can find these services and their importance, aiming to incorporate the constructions and reforms solutions as: renewable energy sources, use of rainwater, reduction of waste of materials, waste recycling, use of sustainable building materials, among others.

• Ecological Brick Factory

In order to generate income and give a productive destination for the rubble, it is intended to install a factory with a small recycling waste recycling plant of easy use for the manufacture of ecological bricks. This factory will be run by the Startup Bazaar, similar to a cooperative, where people living in vulnerable communities would be the employees, thus guaranteeing a source of income for their families. With these actions, we will definitely contribute significantly to reducing the effects of climate change on the urban environment, having a positive environmental impact, integrating the public, private and social spheres in the goal of transforming the construction sector into a more efficient and sustainable, minimizing the cost of construction materials and ensuring decent housing for vulnerable populations.

Which types of stakeholders are involved, in which way? / Quels types de parties prenantes sont impliqués, de quelle façon?

Memorar - Popular Office of Architecture and Construction, is a social business created in 2016 in Salvador, Bahia - Brazil, in partnership with the Federal University of Bahia and mentorship of the Kranium Accelerator; we are organizing the platform business model. We also intend to partner with Builders, Construction Material Stores and Scrap Recycling Plants / Cooperatives to make possible the financial sustainability of the platform and generate income for communities. In addition to these actions implemented, nongovernmental organizations will assist us, giving support in the accomplishment of social actions and engagement of people in their communities. And public institutions, such as the City Hall that is open to partnership, providing physical space and institutional support.

How could the actions be scaled up at the neighborhood or city level? / Comment serait-il possible d'augmenter la portée des actions à l'échelle des quartiers ou de la ville?


The Bazar de Obra project will be implemented in principle in the city of Salvador / BA - Brazil, with actions concentrated in the needy communities of the city; later, we will expand to the metropolitan area of ??the city, and after validating our method of scale, we will expand to other cities in Brazil and other Latin American countries, starting with Colombia, Venezuela and Mexico. The project will benefit the poor communities of the cities, making partnerships with local organizations, adding housing solutions and generating employment and income, always aiming to guarantee sustainability and decrease the environmental impact caused by construction waste in the process.



• 1 to 2 years - Beginning of the implementation of the web platform in the city of Salvador, in partnership with other public and private entities, and actions in partnerships with social businesses for technical assistance in architecture for low-income people

• 3 to 5 years - Implementation of the first ecological brick factory in the Metropolitan Region of Salvador and expansion of the web platform to other cities in Brazil and Latin America, in partnership with public power and non-governmental organizations.

What impact will these actions have on reducing greenhouse gas emissions and adapting to climate change? / Quels impacts auront ces actions sur la réduction des émissions de gaz à effet de serre et l'adaptation aux changements climatiques?



What are the other environmental, economic or social benefits? / Quels sont les autres bénéfices environnementaux, économiques et sociaux?

The project aims to solve the problem of improper disposal of construction material that can be recycled or reused, but which is often taken to landfills when not disposed of on public roads, burdening the state in the urban cleaning of our cities and raising the levels of greenhouse effect; there is an urgent need for a solution such as the Bazaar of Work to give a correct destination, but in addition, the project promotes:

• Reduction of greenhouse gas emissions from construction material factories;

• Reduction of the gases from the decomposition of organic matter, such as methane, to guarantee basic sanitation for dwellings;

• Training of young people and adults, contributing to their socioeconomic development;

• Generation of Employment and Income in vulnerable communities;

• Reduction of consumption and reduction of waste of natural resources such as water, energy and minerals.

What are the most innovative aspects and main strengths of this approach? / Quels sont les aspects novateurs et les principales forces de cette approche?

A participatory solid waste management platform, where consumers and construction professionals can use to give the correct destination for the residues of their buildings and reforms, generating reports of environmental impact and at the same time having the possibility to increase their income / income negotiating recyclable waste, leftover building materials and furniture they no longer want. On this platform, this surplus of registered construction material can be exchanged for others, sold or donated for later use in renovations or construction for social housing; already the waste will have the correct destination for recycling, avoiding to go to landfills, with that the professionals and also ordinary consumers can generate reports and monitor the destination of their waste, in an automated and online way.
