the irruption of polymers from Renewable Resources on the scene of macromolecular science and technology
Green Chemistry, 2011Co-Authors: Alessandro GandiniAbstract:The last few decades have witnessed a spiralling growth of interest in polymers from Renewable Resources within both the scientific and industrial communities. This review attempts to illustrate this state of affairs through a panoramic overview of recent progress in the most relevant areas related to such materials, including the polymerisation of natural monomers and their derivatives, the exploitation of biopolymers, as such, or after appropriate modifications, as well as the preparation of composites and blends. Because of the sheer size and depth of the field, no attempt has been made here to provide a comprehensive coverage, emphasis being placed instead on conveying the extent and originality of contributions reported in the last few years in important domains like sugars and polysaccharides, vegetable oils, lignin, pine resin derivatives, furans, and a series of other monomers.

Materials from Renewable Resources based on furan monomers and furan chemistry: work in progress
Journal of Materials Chemistry, 2009Co-Authors: Alessandro Gandini, Monica Gomes, Dora Coelho, Bruno Reis, Armando J D SilvestreAbstract:The polymerisation of furan monomers and the exploitation of some of the chemical peculiarities of the furan heterocycle have generated a wide diversity of macromolecular materials based on Renewable Resources. We present here recent contributions to this field, including ongoing studies on the synthesis and characterisation of novel furan polyesters and on the application of the Diels–Alder reaction to the preparation of linear and branched thermally reversible polyadducts.

polymers from Renewable Resources a challenge for the future of macromolecular materials
Macromolecules, 2008Co-Authors: Alessandro GandiniAbstract:This perspective article examines the state of the art regarding the field of polymers from Renewable Resources and attempts to give a critical appraisal of the situation related to a representative number of specific materials, in terms of their interest, present degree of advancement, and prospective development within short- and medium-term projections. The selected examples include polysaccharides and their derivatives, lignin, suberin, vegetable oils, tannins, natural monomers like terpenes, and monomers derived from sugars, with particular emphasis on furan derivatives and lactic acid, bacterial cellulose, and poly(hydroxyalkanoates), ending with a brief assessment of the potential role of glycerol and ethanol as future precursors to monomers.

Renewable Resources portfolio optimization in the presence of demand response
Applied Energy, 2016Co-Authors: Sahand Behboodi, David P Chassin, Curran Crawford, Ned DjilaliAbstract:Demand response is viewed as a practical and relatively low-cost solution to increasing penetration of intermittent Renewable generation in bulk electric power systems. This paper examines the question of what is the optimal installed capacity allocation of Renewable Resources in conjunction with demand response. We introduce an integrated model for total annual system cost that can be used to determine a cost-minimizing allocation of Renewable asset investments. The model includes production, uncertainty, emission, capacity expansion and mothballing costs, as well as wind variability and demand elasticity to determine the hourly cost of electricity delivery. The model is applied to a 2024 planning case for British Columbia, Canada. Results show that cost is minimized at about 30% wind generation. We find that the optimal amount of Renewable resource is as sensitive to installation cost as it is to a carbon tax. But we find the inter-hourly demand response magnitude is much less helpful in promoting additional Renewables than intra-hourly demand elasticity.

development and performance evaluation of natural thermal insulation materials composed of Renewable Resources
Energy and Buildings, 2011Co-Authors: Azra Korjenic, Vít Petranek, Jiří Zach, Jitka HroudovaAbstract:Abstract Because energy efficiency in buildings will be evaluated not only based upon heating demand, but also according to the primary energy demand, the ecological properties of the building materials for the whole assessment has become essential. The demand for green building materials is rising sharply, especially insulating materials from Renewable Resources. The application of natural materials has become increasingly important as a consequence of the increasing need to conserve energy, use natural materials, incorporate architecture and construction into sustainable development processes, and the recently promulgated discussions on appropriate disposal of used insulation materials such as polystyrene (EPS). Due to the fact that natural materials are more sensitive to moisture, decomposition factors such as temperature, material moisture content, attacks by microorganisms, and possible decomposition of the material or shorter durability, it is necessary to evaluate the degradation rate of built-in materials and also determine their real in situ hygrothermal properties according to their moisture content, and volume changes. This paper describes the results of a research project carried out at the Vienna University of Technology and Brno University of Technology. The objective is to use jute, flax, and hemp to develop a new insulating material from Renewable Resources with comparable building physics and mechanical properties to commonly used insulations materials. All input components are varied in the tests. The impact of moisture content changes in relation to the rate of change of other properties was the focus of the investigation. The tests results show that the correct combination of natural materials is absolutely comparable with convectional materials.

reuse of the materials recycled from Renewable Resources in the civil engineering status achievements and government s initiatives in taiwan
Materials, 2021Co-Authors: Chi-hung Tsai, Yun-hwei Shen, Wen-tien TsaiAbstract:Growing concerns about the circular economy and sustainable waste management for civil applications of non-hazardous mineral industrial waste have increased in recent years. Therefore, this study presents a trend analysis of industrial waste generation and treatment during the years of 2010-2020, and focused on promotion policies and regulatory measures for mandatory Renewable Resources from industrial sources in Taiwan, including reclaimed asphalt pavement (RAP) material, water-quenched blast furnace slag, and ilmenite chlorination furnace slag. According to the official database of the online reported statistics during the period of 2010-2020, approximately three million metric tons per year of Renewable Resources were totally reused in civil engineering or related cement products, reflecting a balanced supply chain in the domestic market. Among these, water-quenched blast furnace slag accounted for about 90% (about 2.7 million metric tons) in Taiwan. Currently, the legislative framework of sustainable waste management in Taiwan is based on the Waste Management Act and the Resource Recycling Act, but there are some problems with them. In order to effectively reduce environmental loadings and conserve natural Resources to mitigate climate change, some recommendations are addressed from different points of view.

Renewable Resources have limitations that can include location, capacity, cost and availability. California is proactive in the implementation of Renewable energy through legislation and execution of a Renewable Portfolio Standard. This work explores key challenges to achieving high penetrations of Renewables onto California's grid. The Holistic Grid Resource Integration and Deployment (HiGRID) tool has been developed for this analysis and is verified herein. This tool resolves the hourly operation, performance and cost of Renewable and non-Renewable generation Resources. Three Renewable deployment strategies are explored including all wind, all solar photovoltaic, and 50/50 mixture. Initially, wind is the preferred candidate from a cost and required installed capacity perspective; however, as the penetration increases excess wind generation encourages installation of solar. The 50/50 case becomes more cost competitive at high Renewable penetrations (greater than 32.4%) and provides the highest system-wide capacity factor and CO2 reduction potential. Results highlight the value of optimizing the Renewable deployment strategy to minimize costs and emphasize the importance of considering capacity factor and curtailment when representing the true cost of installing Renewables.
