Conteúdo: | Forest extraction and agricultural production leave many materiais that are difficult or impossible to use as ís. Hence they are left in the forests and fields as wastes, causing environmental problems and bringing no revenue. However, uses to make valuable products can be found for such wastes by studying them to understand their chemical and physical properties, including their energy content. One such material is pine needles. However, no data are available on their properties. This paper presents the chemical constituents, calorific value and anatomical and morphological characterization of these needles. In addition, their possible conversion into carbon/activated charcoal through various physical and chemical activations is also discussed. The true density, specific area and calorific values of these carbons were measured. The results indicate that pine needles have potentia I for various value added applications, including as additives in the food industry and production of cooking briquettes and other biofuel uses. The results also indicate that physical activation is less effective compared to chemical activation.
