Promoting the Circular Economy on an Island: Anaerobic Co-Digestion of Local Or...

ABSTRACT: The local waste co-digestion is an interesting option to tackle in reduced and isolated areas like the islands. The islands have limited territory and scarce fuel production. Moreover, organic waste can create serious environmental problems in soil, water and air. Anaerobic co-digestion (AcoD) is a technology fulfilling the concept of waste-to-energy (WtE) based on local resources. The valorisation of...

Water availability and water usage solutions for electrolysis in hydrogen produ...

ABSTRACT: Europe is committed to a new growth strategy with no net greenhouse gases emissions by 2050, where hydrogen has a clear role to play. Portugal's strategy for H2 sets public policies promoting an industry focused on the hydrogen value chain. Considering the production of green hydrogen from renewable sources is key, water electrolysis becomes a priority, and with it, the need to assess the suitability ...

Jet-loop reactor with cross-flow ultrafiltration membrane system for treatment ...

ABSTRACT: Olive oil extraction is one of the ancient agricultural industries all over the Mediterranean area and even today it is of fundamental economic importance for many industries found over the whole Mediterranean. However, this industry generates large amounts of olive mill wastewater (OMW) and due to its physicochemical characteristics it causes severe environmental concerns and management problems in t...

Potencial do biometano em Portugal [Comunicação oral]

Avaliação do potencial e impacto do biometano em Portugal: Sumário executivo

An integrated approach to energy production and nutrient recovery through anaer...

This paper reports on experimental results used to verify the applicability of Vetiveria zizanoides (VZ) as a virtuous energetic crop. VZ produces biogas through its anaerobic digestion, and its nutrient content can be recovered through reuse, after digestion, as an agricultural amendment. Biomethanation tests were conducted with fresh and pretreated VZ, and the results of these tests were compared with those f...

Avaliação do potencial e impacto do biometano em Portugal

ABSTRACT: O PNAER 2020, D.R. 1ª Série Nº 70, de 10 de Abril 2013, identifica políticas e atividades necessárias implementar para garantir o cumprimento do plano nacional relativamente à promoção da utilização das fontes de energia renovável nos diferentes setores. Uma das áreas estratégicas a promover refere-se ao “Biometano”, apresentando como objetivo a avaliação do potencial do biometano em Portugal e suas a...

Implementação de sistemas de Bioenergia: integração dos resíduos com a agricultura

A evolução da nossa sociedade está cada vez mais dependente duma mudança do uso dos recursos naturais e do estilo de vida, que deverá ser baseada numa maior parcimónia e eficiência, na redução de emissões de gases com efeito estufa, na promoção de fontes de energias renováveis. Hoje em dia já se reconhece que os resíduos da nossa civilização, outrora encarados como fonte poluidora e colocados sem proveito em at...

Biogas production from mediterranean crop silages

Anaerobic digestion has proven to be an efficient way for the production of a renewable fuel. The aim of this work was to study the potential use of two crop silages, yellow lupine (Lupinus luteus L.) and oilseed radish (Raphanus sativus var. oleifera cv. Pegletta), for the production of biogas through the process of anaerobic digestion. The use of yellow lupine was due to its capacity for nitrogen fixation, re...
