In this context, the search for sustainable solutions for solid waste management becomes urgent. This study investigated the feasibility of using human hair mass (HHM), generally discarded as waste, as an agricultural input. Composed of approximately 16% nitrogen (N), as well as carbon (C) and sulfur (S), HHM has agronomic potential. The use of HHM residue (HHM) as a fertilizer in three crop cycles and as a substrate component in one crop cycle was evaluated for radish (Raphanus sativus L.) varieties (Redondo Pequeno and Gigante Crimson). The HHM was characterized chemically and physically, including scanning electron microscopy (SEM) analysis. N contents ranged from 10.83% (smoothed) to 15.46% (dyed). A minimum N content of 10% was adopted. Agronomic trials demonstrated that RMCH favors plant root and leaf development, outperforming the control and comparable to urea. Soil analyses revealed that RMCH increased the levels of phosphorus, sulfur, boron, organic carbon, and organic matter, while urea caused losses of C and S. As a substrate, RMCH demonstrated good moisture retention and stimulated initial seedling growth. It is concluded that RMCH has potential as a fertilizer and substrate component, promoting the circular economy by transforming human waste into an agricultural resource.

Overcoming exclusionary paradigms, Environmental Education and Rural Education assume a significant role in promoting rural territorial development, acting not only as adaptation but as an emancipatory axis in the reconfiguration of the relationship between education and the countryside. This research aimed to analyze the macro-trends of Environmental Education present in the conceptions and educational practices of teachers in Municipal Early Childhood Education Centers (CMEI), both rural and urban, in Toledo/PR. This research sought to situate the macro-trends of Environmental Education as a fundamental element in the formation of educational conceptions and practices in different school contexts in the Municipality of Toledo/PR. The results indicate that the promotion of socio-environmental awareness will be built through a critical, emancipatory, and transformative Environmental Education. In the context of Rural Education, even with the need for more effective public policies, this perspective offers solid support for local identities and sustainable practices. It must be understood, however, that the integration of these approaches is of fundamental importance for addressing environmental and social challenges. The research pointed to the imperative need to overcome linearity in pedagogical planning, such that the documentary analysis revealed little emphasis on training for active citizenship and social transformation. The absence of distinct and contextualized elements in the Pedagogical Projects (PPPs) of the rural and urban institutions researched suggests the urgent need to revise pedagogical strategies, reinforcing the urgency of an Educational Praxis that values peasant identity and promotes critical-social development. In conclusion, based on the discussions presented, Critical Environmental Education, combined with Rural Education, is a powerful approach to valuing the rural context and fostering sustainable actions, combining environmental balance with critical thinking.

Thus, according to its importance, this work aimed to structurally, chemically, and morphologically characterize CB, as well as to evaluate its adsorption capacity toward organic substances, seeking to understand the surface behavior of the material. For this purpose, CB was analyzed regarding the point of zero charge (pHPZC), Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDX). The pHPZC was approximately 5.5, indicating that the material presents a positive value in acidic media and tends to be neutral or slightly negative at higher pH values. FTIR analyses revealed the presence of hydroxyl, methyl, and methylene functional groups, associated with a graphitic structure containing surface oxygenated groups, while TGA demonstrated high thermal stability, with mass loss lower than 10% up to 1000 °C. SEM showed that CB has nanometric spheroidal and agglomerated particles, with a fractal structure and high surface area, and these characteristics favor the adsorptive potential of the material. Adsorption tests with erythrosine indicated a high affinity of CB for negatively charged molecules, with rapid saturation kinetics, in about 20 minutes. Our results demonstrate that CB has a predominantly cationic surface under the conditions of this study, being effective in the adsorption of anionic organic compounds; however, requiring prior activation treatments to increase its adsorption capacity for metal ions. Thus, our results highlight a promising potential as an adsorbent in aqueous systems, especially after surface modifications that optimize its interaction with different types of contaminants.

The study examines the pedagogical design of the educational actions in light of the Park Management Plan, considering challenges related to the understanding of public use regulations, risk perception in sensitive areas, and the strengthening of territorial belonging. A qualitative, descriptive-analytical approach was adopted, based on the systematization of experience, field records, participant observation, and critical reflection. The results indicate that the pedagogical cycle of preparing, experiencing, and socializing favored a broader understanding of the ecological processes of the Atlantic Forest, strengthened low-impact behaviors, and contributed to the internalization of conservation regulations and to the recognition of the Park as a collective heritage. It is concluded that educational mediation, when territorialized and articulated with environmental governance, constitutes a strategic instrument for qualifying public use and protecting the Outstanding Universal Value of Iguaçu National Park.
