The incinerator plant is developed by the company Foxx Inova Ambiental, which is pushing forward several Waste-to-Energy projects across Brazil, and comes as part of a public-private partnership signed between the municipality of Barueri and the company. [1] It is planned to burn up to 825 tons of waste per day – the entire waste of Barueri as well as some from neighboring municipalities – and thereby generate electricity of about 17 MW/h, thus more or less covering the energy consumption of 80,000 residents. [1][2][3] While the plant, in the beginning, was supposed to be installed at a former landfill for inert waste in the Jardim Califórnia neighborhood, it is now planned in an industrial area of the Aldeia neighborhood, next to the Tietê river, where it already received a preliminary installation license from Cetesb (São Paulo State Environmental Agency). [1][2] 

The incinerator plans have been fiercely opposed by the wastepicker movement, residents of Barueri and other civil society organizations. Incineration is criticized on the one hand for its adverse impacts on public health and the environment, in particular the generation of toxic ash and emissions. On the other hand, burning waste is problematic from a socio-economic perspective as it disincentives recycling and drives resource use. It thus directly threatens the livelihoods of wastepickers – in Brazil often working in informality or organized in cooperatives – as their incomes strongly depend on access to recyclable material. That clearly contradicts with Brazil’s 2010 adopted National Solid Waste Policy, which provides for incineration only as a means of last resort, while municipalities were encouraged to rather support the recycling sector and promote the inclusion of wastepicker cooperatives in their waste management plans. [4][5] The concerns that the incinerator would particularly put wastepicker livelihoods at risk is also shared by waste experts such as Sylmara Dias, who pointed out that incinerators need primarily solid waste (which is the most recyclable and accounts for 40 % of all produced waste) and have to operate for 24 hours per day in order to be economically viable, which would automatically jeopardize recycling work. As there is already wide skepticism in the public image, incinerators would now become called  “energy recovery units” and promise to prevent any harmful pollution with filters, while in reality there is a clear risk that toxic particles and carcinogenic gases get released. [1][6] 

In 2012 and 2013, street demonstrations against the incineration project took place and wastepicker groups, as well as local residents, participated in public hearings. [1][4][5] Thousands of signatures against the incinerator were collected and information brochures distributed, explaining the adverse effects of incineration on public health. [4] At a public forum on waste solutions held in Barueri in 2013, the representative of Foxx URE and the mayor of Barueri were booed by the audience, after they had stated that residents who positioned themselves against the project were just manipulated by unions. [4] Despite that, the project was not reconsidered and its various benefits for the population were continued to be promised while also street demonstrations continued to take place in 2014. [1][7] 

Project developers claim that the applied waste-to-energy technology was already widely used in Northern Europe and would not come with any harm to the environment and public health; moreover it would be optimal for densely populated metropolitan areas such as São Paulo, Rio de Janeiro and Porto Alegre, whereas they claim - recycling and landfill capacities have been reached. [1][2] However, also the incinerator would generate ash - and a landfill for its final deposit still has to be found. [1] 

The start of construction works was first announced for 2017 and then for 2018 and expected to last between two and two and a half years. [1][2] In 2018, Foxx sold 51% of its shares to the company China Jinjiang Environment, who announced that the "group will uphold high-quality standards and efficiency levels, in order to make the Barueri project a landmark project in Brazil and Latin America, kickstart the development of the local WTE industry, raise local standards of sustainable development, and pave the way for the group's success in Brazil and Latin America" [8]. As it was moreover communicated, parts of the fund for the incinerator would be provided by a World Bank fund. [9] As of 2019, the construction works were still awaiting the final approval of Cetesb but the plant was expected to be realized by 2021. [3]

In 2018, Foxx, which merged with the company Haztec in 2013, became a subsidiary of China Jianjiang Environment, who bought 51 % of the share capital. It was announced that investments of about 62 million Reais into the incinerator would come from the International Finance Corporation (IFC) of the World Bank Group. [9][10]
