Dye effluents cause diverse environmental problems. Methylene blue (MB) dye stands out since it is widely used in the textile industry. To reduce the pollution caused by the MB, we developed biosorbents from tucumã seeds, where the in natura seeds were treated with NaOH (BT) and H3PO4 (AT) solutions and characterized by Boehm titration, point of ze...

Yellow passion fruit peel and cupuaçu seeds are common wastes. Usually, they have few or no applications and are discarded, causing environmental pollution. To use them in a new way and reduce ecological pollution, we obtained the ash of yellow passion fruit peels by calcination. We characterized it using Fourier‐transform infrared spectroscopy wit...

Lignocellulosic materials are mainly formed by cellulose, lignin, and hemicellulose. However, the percentages of these compounds are very variable and may have different characteristics. These materials can be transformed through different processes and are mainly applied as adsorbents, biogas, fertilizers, and catalysts. For this, it is necessary...

Multiple environmental issues are associated with the use of fossil fuels, such as the emission of polluting gases that can generate acid rain and contribute intensely to the greenhouse effect. Aiming to alleviate these problems, biofuels—mainly biodiesel, bioethanol, and biogas—are presented as a sustainable alternative because they are renewable...

As hortas urbanas comunitárias e pedagógicas são cada vez mais presentes nas cidades. São uma manifestação sociocultural de preservação de tradições de cultivo e, uma prática agrícola que contribui para o desenvolvimento sustentável, mas que devem seguir o princípio de uma postura biocêntrica. O presente trabalho propõe promover por meio da horta u...
