Valorisation of Biowastes for the Production of Green Materials Using Chemical Methods

With crude oil reserves dwindling, the hunt for a sustainable alternative feedstock for fuels and materials for our society continues to expand. The biorefinery concept has enjoyed both a surge in popularity and also vocal opposition to the idea of diverting food-grade land and crops for this purpose. The idea of using the inevitable wastes arising from biomass processing, particularly farming and food production, is, therefore, gaining more attention as the feedstock for the biorefinery. For the three main components of biomass—carbohydrates, lipids, and proteins—there are long-established processes for using some of these by-products. However, the recent advances in chemical technologies are expanding both the feedstocks available for processing and the products that be obtained. Herein, this review presents some of the more recent developments in processing these molecules for green materials, as well as case studies that bring these technologies and materials together into final products for applied usage

Rethinking conversion : beyond the religious and the secular

This article seeks to pinpoint some of the consequences of the secularization process – conceived as the dissociation of religion from both state politics and culture – with the aim of broadening the conceptualization of conversion. Conversion is therefore considered to be a social fact beyond the religious and the secular, for which the concept of 'trans-formation' is employed in order to grasp this phenomenon. The concept of trans-formation posits processes of conversion as shifts from intimate convictions to public values. From this perspective, based on a pragmatic sociology of values, religious conversions are put forth as one possible way to qualify trajectories that the concept of trans-formation aims to comprehend. The article ends by considering the status of religious convictions in comparison with convictions otherwise qualified
