Allagoptera arenaria (Arecaceae), commonly known as Bguriri,^is a palm that occurs only along the sandy coastal environments of Brazil. This work carries out a thorough analysis of A. arenaria leaf anatomy, including histochemistry and micromorphology, with special emphasis on leaf epicuticular waxes. Several common features of palms were identified, as well as characters not yet reported for the family or the species. Allagoptera arenaria pinnae possess a one-layered epidermis, hypodermis with two adaxial layers and one abaxial layer, homogeneous mesophyll composed of palisade cells, three different types of collateral veins, a prominent adaxial midrib, and silica inclusions. Although both margins of A. arenaria pinnae have a similar appearance, the shape of the leaf margins can vary. Scales or ramenta were found on the abaxial surface of the midrib on the median and basal portions of the pinnae. Histochemical analysis revealed the presence of polyphenols, flavonoids, lignin, and neutral and acidic lipids. The most distinctive character of A. arenaria pinnae is the presence of a thick layer of epicuticular waxes covering both the adaxial and abaxial surfaces. These results suggest the potential for exploiting A. arenaria as an alternative source of industrial waxes.

“…One of the plants with great potential for use as a source of products with photoprotective activity is the carnauba ( Copernicia cerifera ), a Brazilian palm tree that has leaves covered by a waxy coating. This material, after being extracted from the leaves, becomes a raw material for the production of carnauba wax, the most important vegetable wax from the economic aspect with various applications [59, 60]. This product is of great commercial interest for use in organic filters due to its high content of cinnamate derivatives such as aliphatic diesters of p -methoxicinnamic acid or hydroxy cinnamic acid.…”

Many pathological problems are initiated by ultraviolet radiation (UVR), such as skin cancer, the most commonly diagnosed cancer worldwide. The UVA (320–400 nm) and UVB (290–320 nm) wavelengths may cause effects such as photoaging, DNA damage, and a series of cellular alterations. The UVA radiation can damage the DNA, oxidize the lipids, and produce dangerous free radicals, which can cause inflammation, modify the gene expression in response to stress, and weaken the skin immune response. With a minor penetration, the UVB radiation is more harmful, being responsible for immediate damage. Ultraviolet radiation light emitted by the sun is considered necessary for the existence of life but cause radiation problems, especially in the skin. The photoprotective activities of plant extracts and isolated composts were evaluated by many reports, as well as the correlation of these compounds with the antioxidant activity. This review presents plant compounds with interest to the cosmetic industry to be used in sunscreens such as flavonoids and cinnamates.

ResumoA legislação brasileira prevê que a destinação correta dos resíduos sólidos industriais é obrigatoriedade do gerador. Porém esta é uma das principais dificuldades encontradas, já que o processo produtivo gera resíduos e impactos ambientais. Entretanto, estes resíduos podem ser aproveitados para aumentar a ecoeficiência e como um objeto maior a ecoefetividade, reduzindo os impactos, aumentando a eficiência econômica e ambiental e contribuindo para a sustentabilidade. O setor metal-mecânico igualmente enfrenta a problemática do gerenciamento ambiental, então, o objetivo deste trabalho é avaliar a ecoeficiência e ecoefetividade dos métodos empregados na limpeza de cavacos metálicos contaminados com fluido de corte de empresas metalúrgicas. Foi realizado um estudo sobre a reutilização do cavaco de alumínio, analisando os métodos utilizados, a destinação caso não possível reutilizar e avaliado a ecoeficiência e ecoefetividade. Esta avaliação foi realizada por critérios estudados, onde é possível avaliar métodos como ecoeficientes e ecoefetivos. Na prática foram encontrados somente métodos ecoeficientes e, entre estes, alguns com práticas ecoefetivas. Os resultados evidenciam que a cultura de reparar, reutilizar, reciclar e destinar, ao invés de promover ações como a remodelagem de um sistema produtivo em ciclo fechado onde não há geração de resíduos é ainda mais prático e realístico.

ANALYSIS OF METAL CHIP RECYCLING METHODS CONTAMINATED CONSIDERING APPROACHES TO ECO-EFFICIENCY AND ECO-EFFECTIVENESS AbstractThe Brazilian law requires that the proper disposal of industrial solid waste is mandatory of the generator. However, this issue becomes one of the main difficulties encountered in order that the manufacturing process generates waste and environmental impacts. Still, this waste can be utilized to increase eco-efficiency and as a larger object to eco-effectiveness, reducing the impacts, increasing the economic and environmental efficiency and contributing to sustainability. The metal-mechanical sector also faces the problem of environmental management, therefore, the aim of this study is to evaluate the eco-efficiency and ecoeffectiveness of the methods used in the cleaning of metallic chips contaminated with cutting fluid metallurgical enterprises. A study on the reuse of aluminum chips was done by analyzing the cleaning methods used, the allocation if cannot be reused and evaluated within the aforementioned characteristics, which is the most eco-efficient and/or eco-effective. This review was performed by studied criteria to which you can evaluate methods as eco-efficient and eco-effective. In practice found only eco-efficient methods, and among them, some with eco-effective practices. The results show that the culture of repair, reuse, recycle and intended instead to promote actions such as the remodeling of a production system in a closed cycle where no waste generation is now even more practical and realistic.
