“…Because the PAC is an outcrop of granite origin and close to one of Brazil's most important ornamental stone beneficiation industries (Xavier, Azevedo, Alexandre, Monteiro, & Pedroti, 2019), the locale is extremely vulnerable to speculative mining. Despite the importance of the mining sector for the Espírito Santo economy, mining activity is the biggest threat to inselberg vegetation, not only in Brazil but also around the world (Porembski et al, 2016).…”

Inselbergs are granitic or gneissic rocky outcrops prevalent in the landscape of southeastern Brazil. These ecosystems represent islands of isolated habitats that harbor a peculiar flora with high richness and endemism. The present study lists the species of vascular plants occurring in the Pedra da Andorinha Complex, located in the municipality of Jerônimo Monteiro/Cachoeiro de Itapemirim, southern Espírito Santo state, aiming to generate subsidies for the creation of a protected area. The survey was performed between July 2017 and October 2018, resulting in a record of 121 species, 96 genera, and 40 families. Bromeliaceae (17), Orchidaceae (12) and Fabaceae (10) were the richest families. The phytophysiognomy of exposed rock vegetation comprises a greater number of species (79 species) compared to the woody rupicolous communities (42). Eighteen of the collected species are threatened by extinction; a new species was discovered; and five were described based on materials previously collected in the studied location — Alcantarea patriae, Anthurium martinellii, Coleocephalocereus uebelmanniorum, Stigmatodon attenuatoides and Pitcairnia azouryi, the first four being endemic to the region. We also found Tabebuia reticulata, a rare species among Brazilian flora. Our results highlight the biological importance of the Pedra das Andorinhas Complex and reinforce the need to create a protected area to preserve biodiversity and the regional natural heritage.

“…Despite the great importance of this sector for the country's economic development, there is an increasing need for the main raw material of the red ceramic industry, clay, in which its exploration is simultaneously intensified and, consequently, increasing environmental impacts [2]. In this way, researchers sought solutions that would reduce damage to the environment, such as the incorporation of industrial waste in the clay matrix [3,4,42,43] The red ceramic industry represents 4.8% of the civil construction industry in Brazil, comprising 6903 companies that generate an equivalent to R$ 18 billion in annual sales [5]. According to data from the Ministry of Mines and Energy, the main products developed in the North are bricks and blocks [6].…”

“…Studies demonstrate great potential and improvements in traditional ceramic products with the incorporation of granite waste [2,3,[25][26][27][28][29][30][31][32][33][34][35]. The main reason for this reuse to be possible is the compatibility and mineralogical heterogeneity between the clays used in the traditional ceramic industry and the by-product of the granite exploration activity [27,29,31,35].…”

“…The main reason for this reuse to be possible is the compatibility and mineralogical heterogeneity between the clays used in the traditional ceramic industry and the by-product of the granite exploration activity [27,29,31,35]. In addition, fluxing compounds, commonly found in granite residue, contribute to the development of a greater amount of vitreous phase during the sintering procedure, filling the pores and increasing the durability of the red ceramic pieces providing an improvement in the quality of the product [3,35,15].…”

“…The literature presents research with quantities of granite residues from 5% to 60% (by weight) introduced in red ceramic [3,14,22,24,26,27,[33][34][35]. Since ceramic products for civil construction were the products most investigated in the studies [14, 22, 25-27, 30, 32, 34].…”

The increase in the exploitation of raw materials in the civil construction sector has led to an increase in damage to the environment, mainly due to the improper disposal of granitic waste. However, this fact has caused damage to the environment. Therefore, this research aims to analyze the influence of the introduction of granite waste in a clay matrix aiming its use in the red ceramic industry. For this, the clay from the ceramic pole in the city of Iranduba -AM and granite waste from a company located in the municipality of Presidente Figueiredo -AM were collected. Formulations were made containing three levels of waste (0, 10 and 20% mass) and three firing temperatures (1173, 1273 and 1373K). The materials were characterized by X-ray fluorescence spectroscopy, X-ray diffraction, scanning electron microscopy and the following technological properties were determined: water absorption; linear retraction; apparent porosity; specific mass; and 3-point flexural rupture module. The results showed that the glassy phases generated provide a better densification of the formulations with 20% of waste, sintered at 1373K, as they presented favorable mechanical properties for the manufacture of red ceramic products, providing a correct destination of the waste and providing alternatives for the social, economic context and environmental impact of the Amazon region.
