Abstract:
This study explores the impact of green energy strategies on natural resource sustainability in Pakistan, utilizing data from 1999 to 2022 and applying the ARDL estimation technique. The primary focus is on understanding how renewable energy consumption and production influence natural resource rents. Empirical results indicate a complex relationship: renewable energy consumption is negatively correlated with natural resource rents, suggesting that increased consumption of renewable energy may reduce the exploitation of natural resources. Conversely, renewable energy production shows a positive correlation with natural resource rents, implying that boosting renewable energy production can enhance the value derived from natural resources. These findings underscore the dual role of renewable energy in promoting sustainability. On the consumption side, a shift towards renewables can alleviate pressure on natural resources, fostering long-term ecological balance. On the production side, investing in renewable energy infrastructure appears to complement the efficient use of natural resources, potentially increasing economic rents. Policymakers should encourage renewable energy consumption through incentives and subsidies, reducing dependence on non-renewable resources and mitigating environmental degradation.

Abstract:
AbstractThe drive for greater use of renewable materials is one that has recently gained momentum due to the need to rely less heavily on petroleum. These renewable materials are defined as such since they are derived from plant-based sources. Some renewable materials also offer properties that conventional materials cannot provide: hierarchical structure, environmental compatibility, low thermal expansion, and the ability to be modified chemically to suit custom-made applications. Nature's materials, particularly from plant- and animal-based polysaccharides and proteins, have hierarchical structures, and these structures can be utilized for conventional applications via biomimetic approaches. This issue begins with an article covering renewable polymers or plastics that can be used to generate block copolymers (where two polymers with specific functions are combined) as an alternative to conventional materials. Applications of renewable polymers, such as cellulose from plants, bacteria, and animal sources, are also covered. Also presented are the use of bacterial cellulose and other plant-based nanofibers for transparent electronic display screens and, in a wider sense, the use of cellulose nanofibers for composite materials, where renewable resources are required to generate larger amounts of material. Finally, this issue shows the use of biomimetic approaches to take the multifunctional properties of renewable materials and use these concepts, or the materials themselves, in conventional materials applications.

Abstract:
Renewable resources related to biomass, waste materials and recycled materials are an important concept in the principles of green chemistry, development of biorefineries and sustainability development. This thesis reports the repurposing of renewable resources which included wheat straw, biomass ash, waste cardboard (paper) and paper de-inking residues (DIR) to extract, synthesize and produce potentially high value chemicals, materials and composites. Biosilicate solutions were successfully extracted from biomass ash including wheat straw ash and miscanthus ash with aqueous potassium hydroxide solutions. Systematic analyses had been applied on the extraction of biosilicate solutions to obtain different types of silicate solutions for further applications of binder and mesoporous materials. Biosilicate solutions extracted from miscanthus ash were utilized as binders to make bioboards, whilst biosilicate solutions extracted from wheat straw ash were utilized as a silica resource to synthesize biobased mesoporous materials, namely bio-MCM-41 and bio-SBA-15. N2 porosimetry analysis revealed that mesoporous silica made from biosilicate solutions gave a surface area of bio-MCM-41 of >1000 m2 g-1 and a surface area of >800 m2 g-1 for bio-SBA-15. XRD, SEM and TEM analyses for both bio-MCM-41 and bio-SBA-15 revealed significant ordering pores, structure and the hexagonal arrays. Different kinds of renewable resources including wheat straw, pea pod waste and paper de-inking residue with the binder of biosilicate solutions and other chemical additives such as protein and starch were processed to bioboards. Also, wheat straw powder was added into cardboard/paper sheets to decrease the cost of paper manufacture and to improve mechanical properties. De-waxed wheat straw cardboard/paper sheets was successfully incorporated in to paper pulp to give a tensile index of 30-34 Nm/g similar with respect to conventional cardboard paper (tensile index of 30-32 Nm/g). A brief study to elicit sugars to the surface of cardboard/paper thus producing an in-situ sticky surface using low temperature microwave irradiation was conducted. Although it’s not conclusive, an aqueous fraction was expelled that contains organic matter (based on C-H stretch absorption bands noted in FT-IR), which may be due to sugars.

Abstract:
A series of polyurethane (PU) and polyurethane-urea (PUU) elastomers derived from a renewable source have been synthesised and characterised extensively. Comparisons have been made to analogous series of elastomers utilising petroleum derived diisocyanates. The renewable elastomers utilised a difuranic diisocyanate (DFDI) derived from furfural, a readily available raw material synthesised from agricultural waste. DFDI was synthesised using a modified version of a published procedure, utilising triphosgene for the formation of the diisocyanate. The reaction kinetics of the diisocyanates used were compared using an adiabatic temperature rise technique in both catalysed and uncatalysed reactions, showing that DFDI reacts at approximately one fifteenth the rate of MDI with primary alcohols. The polyurethane series comprised MDI/DFDI and 1,4-butanediol (BD) hard segments (HS) and polytetrahydrofuran (PTHF) soft segments (SS) at 1, 2 and 2.9 kDa molecular weights. The PUU series utilised the 2kDa PTHF SS and the amine precursor to the diisocyanate, in effect simulating the HS produced in a water blown (polyurethane-urea) foam. In all PU elastomers the DFDI variants displayed much greater degrees of phase separation as evidenced by lower soft segment (SS) Tgs observed by both DSC and DMTA measurements, greater invariants observed in SAXS frames, more SS crystallinity observed in WAXS data and a much more clearly defined morphology observed in tapping mode AFM images. Crystallinity within the SS was found to be much higher in DFDI based elastomers, whereas crystalline hard segments were only observed in MDI based PU elastomers and was more pronounced at higher HS contents and at lower SS molecular weights. The PUU elastomers showed very clear morphologies in AFM images but were found to possess a lower degree of phase separation overall, agreeing with previous literature suggesting that the stronger hydrogen bonding of urea groups can hinder phase separation.

Purpose/aim: The purpose of this dissertation is to find out the effect of waste disposal on environment and to explore the effect of renewable resources on economy. We use some data to test and verify the existence of effects. Design/methodology/approach: We use our questionnaires to collect data, and analyze the data in statistical tests. We use case studies to find examples to verify the significance of waste classification and renewable resources as well as the problems in main cities of China. Findings: The analysis shows that we need to focus on waste classification education, if we want to apply it in real life. The best way to use renewable resource more widely is to aquire government support. If we can carry out waste classification better, we can make use of more renewable resources. Originality/value: The value of this paper is that we prove that using waste classification and renewable resource can increase economic growth rate and protect the environment. It is also important because economic growth brings about the reduction of environment quality. When the environment quality decreases, the economic level will also decrease.

Abstract:
The global energy system is dominated by the use of fossil fuels. This system suffers from several problems, such as different environmental issues, while the long-term energy security is sometimes questioned. As an alternative to this situation, a transition to a global energy system based on renewable energy technologies, to a large extent solar and wind energy, is commonly proposed. Constructing the technology needed for such a transition requires resources and how fast this could happen is somewhat disputed. This thesis explores methods to assess the potential constraints for realizing such a transition by looking at potential technology growth rates and outlooks of production of the required natural resources. The thesis is based on three papers presenting case studies that look at growth rates of wind energy as well as future production outlooks of lithium and phosphate rock. Using different types of growth patterns reaching proposed installed capacities of wind power, annual commissioning requirements are investigated, taking account for the limited life expectancy oftechnology. Potential outlooks of mineral production are explored using resource constrained curve-fitting models on global lithium production. A more disaggregated model looking at individual countries are used on phosphate rock production to investigate new perspectives on production outlooks. It is concluded that the growth rates of individual energy technologies affect the resource requirements and prospective constraints on energy transitions. Resource constrained modelling of resource production can provide spans of potential outlooks for future production of resources required for anenergy transition. A higher disaggregation of the modelling can provide new perspectives of potential constraints on future production. These aspects should be further investigated when proposing alternative future energy systems.

Abstract:
In this century, the major use of synthetic polymers have been as replacements for more traditional materials, particulary in packaging. Today the packaging industry is by far the major user of plastics. Another interesting application of these materials is drug delivery systems. Polymers have played an integral role in the advancement of drug delivery technology by providing controlled release of therapeutic agents in constant doses over long periods, cyclic dosage and tunable release of both hydrophilic and hydrophobic drugs. Modern advances in drug delivery are now predicated upon the rational design of polymers tailored for specific cargo and engineered to exert distinct biological functions. Aliphatic polyesters such as poly(L-lactic acid), poly(butylene succinate), and polyhydroxyalkanoates among others, constitute primary examples of bio-based polymers that distinguish by being fully renewable and displaying partial or total biodegradability. This Ph.D. Thesis is devoted to the synthesis of aliphatic random and block polyesters from renewable resources with application for packaging and drug delivery. The main goal of this project is to develop new bio-based polymers with similar or even improved properties compared to those of conventional plastics obtained from non-renewable sources. The two cyclic acetals, 2,3-di-O-methylene-L-threitol and dimethyl 2,3-di-O-methylene-L-threarate, were used for the synthesis of two series of PBS copolyesters differing in which unit, butylene or succinate, was replaced, in addition of the corresponding parent homopolyesters. 2,4:3,5-di-O-methylene-D-glucitol was used for the synthesis of PBS copolyesters by melt polycondensation. Three series of polyalkanoates (adipates, suberates and sebacates) were synthesized using as monomers three sugar-based bicyclic diols derived from D-glucose and D-mannose. ABA triblock copolyesters were synthesized by ROP of L-lactide in solution initiated by telechelic D-glucose- and L-tartaric-based polyester macroinitiators. The synthesized polyesters were characterized by nuclear magnetic resonance (NMR) spectroscopy, gel permeation chromatography (GPC) and viscosimetry. Thermal properties were analyzed by differential scanning calorimetry (DCS) and thermogravimetry (TGA). Crystalline structure of polyesters was studied by X-ray and its mechanical properties were evaluated as well. Hydrolytic degradation and biodegradation assays were followed by GPC and NMR. Nanoparticles made from triblock copolyesters were characterized by scanning electron microscopy (SEM) and dynamic light-scattering (DLS).<br>En este siglo, el mayor empleo que se les ha dado a los polímeros sintéticos ha sido como sustitutos de materiales más tradicionales, en particular, materiales para envase y embalaje. Hoy en día la industria de envasado es, por mucho, la mayor consumidora de plásticos. Otra aplicación interesante de estos materiales son los sistemas de administración de fármacos. Los polímeros han jugado un papel fundamental la tecnología de administración de fármacos al proporcionar un medio de liberación controlada de agentes terapéuticos en dosis constantes durante largos periodos; la dosificación cíclica y la liberación sintonizable de fármacos hidrofílicos e hidrofóbicos. Actualmente, los avances modernos en la administración de fármacos se basan en el diseño racional de polímeros para la liberación de dosis controladas que modifican distintas funciones biológicas de forma específica. Los poliésteres alifáticos tales como el poli(ácido L-láctico), el poli(succinato de butileno) y los polihidroxialcanoatos, entre otros, constituyen ejemplos primarios de polímeros de base biológica que se distinguen por ser completamente renovables y presentar biodegradabilidad parcial o total. Este trabajo de doctorado está dedicado a la síntesis de poliésteres alifáticos al azar y de bloques a partir de recursos renovables con aplicación para el envasado y la administración de fármacos. El objetivo principal de este proyecto es desarrollar nuevos polímeros biológicos con propiedades similares o incluso mejores en comparación a los plásticos convencionales obtenidos a partir de fuentes norenovables. Los dos acetales cíclicos, 2,3-di-O-metileno-L-treitol y dimetil 2,3-di-O-metileno-L-trearato, se usaron para la síntesis de dos series de copoliésteres de PBS que difieren en qué unidad, butileno o succinato, se reemplazó, además de los homopoliésteres originales correspondientes. Se usó 2,4:3,5-di-O-metileno-D-glucitol para la síntesis de copoliésteres de PBS mediante policondensación en estado fundido. Se sintetizaron tres series de polialcanoatos (adipatos, suberatos y sebacatos) usando como monómeros tres dioles bicíclicos base azúcar derivados de D-glucosa y D-manosa. Los copoliésteres tribloques ABA se sintetizaron mediante ROP de L-láctido en solución iniciada por macroiniciadores de poliester telequelico basados en D-glucosa y L-tartárico. Los poliésteres sintetizados se caracterizaron por espectroscopia de resonancia magnética nuclear (RMN), cromatografía de permeación en gel (GPC) y viscosimetría. Las propiedades térmicas se analizaron mediante calorimetría de barrido diferencial (DCS) y termogravimetría (TGA). La estructura cristalina de los poliésteres se estudió mediante rayos X y sus propiedades mecánicas también se evaluaron. La degradación hidrolítica y los ensayos de biodegradación fueron seguidos por GPC y NMR. Las nanopartículas hechas de copoliésteres tribloque se caracterizaron por microscopía electrónica de barrido (SEM) y dispersión de luz dinámica (DLS).

<p>High molecular weight poly(ester-carbonate)s have beenprepared by a two-step chain-extension reaction performed onoligomeric αω-bishydroxyl-terminatedpoly(1,3-propylene succinate).αω-Bishydroxyl-terminated copolymeric oligomers of1,3-propylene succinate/1,4-cyclohexanedimethylene succinatewere obtained by thermal polycondensation of1,3-propanediol/1,4-cyclohexanedimethanol/succinic acidmixtures having different composition, and subsequently chainextended using phosgene as coupling agent, which leads toaliphatic/alicyclic copoly(ester-carbonate)s.

Abstract:
Butanol, butyric acid and butyraldehyde are important 4-carbon oxychemicals typically generated from petro-chemical sources. All have significant markets in the food industry either for direct use as flavorings or as chemical feedstocks for generating butyric acid and butyraldehyde derived flavour compounds. Strong consumer sentiment against the consumption of petro-chemical derived products yields a demand for butyrate and butyraldehyde generated through all-natural methods. The bacterial fermentation production of butyric acid as well as bioconversion of butanol to butyraldehyde by yeast is presented in this work as a means of producing these products naturally. This thesis demonstrates the fermentation production of butyric acid with the Gram-positive anaerobic bacteria Clostridia tyrobutyricum. The organism consumes monomeric hexoses and pentoses to generate the carboxylic acids lactate, acetate and butyrate. The fermentations undertaken in this thesis were performed with either glucose or xylose as the primary carbon source in minimal media. Butyric acid studies were performed under anaerobic conditions as batch fermentations with lag, log and stationary phase growth being monitored by the optical density of the fermentation broth. Samples were drawn throughout the fermentations and HPLC analysis was performed to determine sugar consumption and butyric acid production over time. Another element expounded in this thesis is the potential use of the economical and renewable resource hot water extracted (HWE) hemicellose as a substrate for Clostridial fermentation. HWE hemicellose is produced as a waste stream from the pulp and paper industry and is converted to fermentable xylose with the concomitant release of acetic acid from the acetyl groups on the xylan backbone. With the presence of such a high concentration of acetic acid, microbial inhibition occurs and the productivity of xylose fermentation to butyric acid is diminished with the increased lag phase. C. tyrobutyricum xylose fermentation studies were performed with synthetic media challenging the fermentation with up to 26.3 g/L acetic acid to gain an understanding of the effects of acetic acid inhibition. Once the acetic acid induced lag phase growth was characterized this work was furthered by adapting a strain of C. tyrobutyricum to 26.3 g/L acetic acid conditions and demonstrating that this pre-adaptation could drastically reduce the acetic acid induced lag phase of a batch fermentation. From this set of studies, it is noted that the presence of acetic acid in the media increases carbon efficiency of the fermentation as during stationary growth C. tyrobutyricum re-uptakes free acetic acid from the environment and converts it into butyric acid. This thesis also demonstrates the bioconversion of butanol to butyraldehyde by the methylotrophic yeast Pichia pastoris. P. pastoris were grown to high cell densities under glycerol feed and then induced to produce the endogenous alcohol oxidase (AOX) enzyme by beginning the culture on methanol consumption after a short starvation period. AOX converts short chain aliphatic alcohols to the corresponding aldehyde with the utilization of oxygen. The AOX enzyme is inhibited by the final product butyraldehyde so studies were performed utilizing alternative amine based pH buffering systems which also aid the bioconversion by binding free butyraldehyde as a Schiff-base. By binding the butyraldehyde longer bioconversions were observed. For these conversions, AOX activity was monitored with an absorbance based enzyme assay and the butanol substrate and butyraldehyde product were determined by gas chromatography.<br>Godkänd; 2012; 20120906 (adajar); LICENTIATSEMINARIUM Examinator: Associate Professor Ulrika Rova, Institutionen för samhällsbyggnad och naturresurser, Luleå tekniska universitet Diskutant: Dr Christian Andersson, Formox AB, Perstorp Tid: Fredag den 12 oktober 2012 kl 10.00 Plats: C305, Luleå tekniska universitet

Abstract:
The Department of Energy has listed 5-hydroxymethylfurfural (HMF) and 2,5-furandicarboxylic acid (FDCA) as two of the twelve building blocks derived from cellulosic biomass. HMF can serve as a renewable platform for the production of fuels and chemicals. Our research goal is to develop novel methods for the conversion of renewable resources to feedstock chemicals for polymer synthesis. The Diels-Alder reaction, the cycloaddition of alkenes and dienes, has become one of the most important synthetic methods used in organic chemistry. We were interested in carrying out Diels-Alder reactions with derivatives of HMF. Naphthalene analogs of terephthalic acid were synthesized by reacting HMF derivatives with benzyne which could lead to the formation of bio-based polyethylene terephthalate (PET) analogs.

Abstract:
The carbon reduction and sustainability goals of the University of California, Irvine require increased penetrations of intermittent renewables on the campus microgrid. These increased intermittent renewables create operational challenges related to conventional energy resources. To study these operational challenges, a holistic campus resource dispatch model was developed. The campus energy resources consist of a microgrid with ten 12 kV circuits emanating from one substation, 4 MW of solar photovoltaic, a central combined heat and power plant (19 MW), a district heating and cooling system, and an electric chiller-thermal energy storage system that provide electricity, heat, and cooling. The holistic model includes dynamic models of the combined heat and power (CHP) plant, the electric chiller-thermal energy storage system, and various renewable resources. In addition, models for complimentary technologies were also created to investigate their potential to increase renewable penetration on the campus microgrid. These include battery energy storage, demand response, and energy efficiency. Simulations with the holistic campus resource model revealed several important conclusions: (1) Regardless of renewable resource type, impacts on the CHP plant remains the same, i.e., increased renewable penetrations create reduced CHP plant capacity factors; (2) Local two axis CPV provides lower costs of electricity than local fixed PV at renewable penetrations below 23% after which local fixed PV provides a lower cost of electricity (3) Introduction of a battery into the campus microgrid achieves higher renewable penetrations and improves the operation of CHP plant; and (4) Electric energy storage does not always prove cost effective (i.e., At low renewable penetrations, electric energy storage is not cost effective; At 17% renewable penetration, electric energy storage begins to become cost effective).

Abstract:
Hydrogen can be produced from various primary resources by using different processes. The full benefits of hydrogen production can be obtained when it is produced from renewable energy resources. Among these emerging renewable energy resources, marine and hydrokinetic (MHK) energy systems lower variability in the energy production. Also, more than 50% of the total US population resides near water bodies. In this paper, a brief review of renewable energy-based hydrogen production systems is provided, the emission level of both conventional and renewable energy sources for producing the same amount of hydrogen are compared using GREET model, and research needs for further MHK-based hydrogen production systems are discussed. The results showed the significant emission reductions obtained from renewable-based hydrogen production systems. Moreover, the study showed the potential of producing the same amount of hydrogen with less resource quantity of wave energy compared to that from other renewables such as solar energy.
