1. ADDITION OF BOILER CHARCOAL WASTE TO COMPOST FOR USE AS SUBSTRATE FOR VEGETABLE SEEDLINGS
ABSTRACT The recovery of waste from the broiler production chain (BPC) is consistent with the principles of a circular economy. Besides turning waste into organic compost, its use as substrate for the production of vegetable seedlings further increases its economic value. However, it is necessary to adapt its characteristics to enable its use as substrate. T

2. Painéis de partículas elaborados do mesocarpo do dendê como alternativa ao MDF utilizado na construção civil
RESUMO A escassez dos recursos florestais integrada à necessidade de aquisição de produtos mais ecológicos demanda o uso de outros tipos de biomassa, além da madeira no setor construtivo. Diante disso, o mesocarpo do dendê - resíduo oriundo da agroindústria e com grande potencial de utilização para desenvolvimento de novos materiais - surge como al

3. Investigation on chemical composition and optimization of essential oil obtainment from waste Pinus taeda L. using hydrodistillation
ABSTRACT: The extraction of essential oils obtained by the hydrodistillation of needles/twigs waste of Pinus taeda L. was optimized by applying response surface methodology (RSM), with 24 full factorial design, in order to improve oil essential production, and aggregate value to the production chain of pine wood. Through the model it was possible to ascertai

7. Uma alternativa para a glicerina oriunda da produção do biodiesel : preparo de polióis e aplicação em adesivos poliuretânicos
This work reports the purification of the residual glycerin, a coproduct of the biodiesel production and their esterification with fatty acids from vegetable oils. The obtained products, mainly monoacylglycerides (polyols), were used for the preparation of urethanic adhesives. Firstly, residual glycerin was purified by vacuum distillation and the acid cataly

10. Environmental assessment of economic production of wood from native species in two municipalities in the Brazilian Amazon / Avaliação ambiental econômica da produção de madeira de espécie nativa em dois municípios na Amazônia Brasileira
A exploração das florestas nativas e das plantações florestais no Brasil tem um imenso potencial. No entanto, na Amazônia, a exploração das florestas nativas tem se dado predominantemente de forma predatória com um enorme desperdício dos recursos madeireiros e não madeireiros. O objetivo desta pesquisa foi avaliar a cadeia produtiva da madeira de e
