Energetic and biochemical valorization of cork boiling wastewater by anaerobic ...

In addition to energy benefits, anaerobic digestion offers other interesting advantages. The cork industry is of great environmental, economic and social significance in the western Mediterranean region, with Portugal being the world-leading producer and exporter. Cork boiling wastewater (CBW) is a toxic and recalcitrant organic effluent produced by this sector, which constitutes a serious environmental hazard...

Cork wastes treatment and biogas production

Cork industry is an important economic and social sector in the western Mediterranean region. Portugal is the producer and processing leader of this sector. The cork processing industry gives rise to several effluents that must be treated and valorised. This work is a part of a study that aims to develop an integrated process in order to maximize the valorization of the different wastes/effluents of the cork pr...

Phenolic compouds with antiradical activity from the cork boiling wastewater an...

This work aims to develop a procedure that explores the different types of valorization that can be obtained by integrating a biological process, such as the anaerobic digestion, to promote the bioconversion of the industrial cork effluents (cork boiling wastewater, CBW).

Cork wastes as energy sources

This work shows the possibility of using cork wastes form cork processing for energy production. In cork processing operations an important waste is produced, cork powder, the main waste of the cork industry, which is estimated to reach over 30000 tons/year. There are various types of cork powders with higher calorific values ranging from 4,000-7,000 Kcal/kg. This powder is commonly burned to produce steam or h...

Cork boiling wastewater anaerobic digestion process leads to biogas and valuabl...

Cork is the outer bark of the cork-tree (Quercus suber L.) and it is a very important industrial sector in western Mediterranean region, being Portugal the world-leading producer and exporter (1). The anaerobic digestion has never been applied to the treatment and valorization of the industrial cork effluents (cork boiling wastewater, CBW). The goal of the present work is evaluate the role of this biological p...

Cork, energetic and environmental aspects

REDECOR: Rede temática do sobreiro e da cortiça

A REDECOR - Rede Temática do Sobreiro e da Cortiça teve início numa outra rede designada por RTC (Rede Temática da Cortiça) criada, em 2004, no âmbito da Sociedade de Portuguesa de Materiais e da sua Divisão de Materiais de Origem Florestal, de âmbito mais restrito, rede essa que se pretendeu alargar numa fase posterior, dando origem à REDECOR.

Cork boiling wastewater treatment and biogas production

Cork boiling wastewater (CBW) is a very important effluent of the cork processing industry which is produced in the western Mediterranean region and western north of Africa. CBW has no utility till now constituting an environmental hazard. It is a complex liquid stream which is produced during the boiling of the cork planks. This process step is one of the key operations in cork processing. CBW is known as havi...

Water content control to improve space charge storage in a cork derivative

The influence of humidity content on the electrical and dielectric properties of a composite made from recycled TetraPak® containers and granulated cork was studied. The material components have been dried before preparation and after the composite was conditioned by keeping the samples in a dry environment (desiccator) or in an oven at high temperature (70oC in air). The differences observed in electrical prop...

REDECOR: Uma rede de informação ao serviço do sector corticeiro

A cortiça é um recurso natural da maior importância para o nosso País, qualquer que seja o ponto de vista: económico, ambiental, social. O sector corticeiro é um dos "clusters" de maior interesse a desenvolver e apoiar futuramente no nosso País, podendo mesmo ser apontado como um dos desígnios nacionais.
