Cellulosic Biofuels

Cellulosic biofuels are not as far off as often assumed. EESI's investigation of this issue found some pilot scale cellulosic biofuel production facilities already online and many more demonstration and commercial scale biorefineries under construction or on the drawing board. In fact, 55 cellulosic biorefineries are complete, under construction or in the planning stage in a total of 31 states across the country, adding up to an expected nameplate capacity of 629.5 million gallons per year (MGY) and a potential expansion to 995 MGY. Most of the demonstration and commercial scale facilities are scheduled to start operation in 2009 or 2010

De Roadmap combineert korte- en middellange termijn mogelijkheden (commerciële implementatie, demonstratie plants, pilot plants en gerelateerd toegepast onderzoek) met strategisch onderzoek voor de langere termijn. Tevens zijn vier z.g. Moonshots uitgewerkt, als voorziene bioraffinagestrategieën met een grote potentie voor de Nederlandse economi

Neoliberalising technoscience and environment: EU policy for competitive, sustainable biofuels

This chapter discusses how EU biofuels policy: stimulates new markets for knowledge as well as resources; assumes that markets drive beneficent innovation; and thus deepens links between markets, technoscience and environment. The theoretical concept ‘neoliberalising the environment’ is extended to links between technoscience and natural resources

Use of Agricultural Residue Feedstock In North Dakota Biorefineries

Rising prices and uncertain supplies of petroleum, together with environmental concerns regarding fossil fuel combustion, have enhanced interest in biobased products and fuels. This study analyzes the feasibility of a multi-product biorefinery that uses wheat straw as feedstock to produce ethanol, electricity, and cellulose nanofibers. Nanofibers (nanowhiskers) would be used as reinforcements in a biobased nanocomposite material that could substitute for fiberglass in many applications. The growth of a biobased industry could have major economic development implications for the Great Plains/Midwest region.biomass, biomaterials, cellulose nanofibers (CNFs), economic development, ethanol, wheat straw, Agribusiness, Resource /Energy Economics and Policy,

The outlook of the production of advanced fuels and chemicals from integrated oil palm biomass biorefinery

The palm oil industry generates significant amounts of solid wastes. The solid wastes, also known as oil palm biomass, includes the trunk (OPT) and fronds (OPT) from the plantation, and empty fruit bunch (EFB), mesocarp fibre (MF) and palm kernel shell (PKS) from the processing mills. Oil palm biomass is not effectively recycled for other applications, and existing disposal practices can cause adverse impacts on the environment. As oil palm biomass is a readily available lignocellulosic biomass, it has the potential to be a low-cost feedstock for conversion into higher value products. The first part of this study provides a comprehensive review of utilisation of oil palm biomass for the production of biofuels, chemicals and biomaterials through direct utilisation and physical conversion, biochemical conversion, thermochemical conversion and synthesis of lignin-based materials. The second part of this study discusses the opportunity for biorefinery development based on existing bioproducts from oil palm biomass, for the production of advanced fuels and platform chemicals that have not been explored in oil palm biomass research. This study proposes integrated biorefinery concepts via the integration of existing oil palm biomass biorefinery products with thermochemical process for upgrading the bioproducts into higher values products. The high-value products integrated biorefinery products include advanced biofuels, fuel additives and platform chemicals. The integrated biorefinery development for oil palm biomass processing is expected to improve the economics of the production of biomass-derived renewable energy and enhance the sustainability of palm oil industry

Pretreatment Processes of Biomass for Biorefineries: Current Status and Prospects

Producción CientíficaThis article seeks to be a handy document for the academy and the industry to get quickly up to speed on the current status and prospects of biomass pretreatment for biorefineries. It is divided into two biomass sources: vegetal and animal. Vegetal biomass is the material produced by plants on land or in water (algae), consuming sunlight, CO2, water, and soil nutrients. This includes residues or main products from, for example, intensive grass crops, forestry, and industrial and agricultural activities. Animal biomass is the residual biomass generated from the production of food from animals (e.g., manure and whey). This review does not mean to include every technology in the area, but it does evaluate physical pretreatments, microwave-assisted extraction, and water treatments for vegetal biomass. A general review is given for animal biomass based in physical, chemical, and biological pretreatments

Using Cellulosic Ethanol to ‘Go Green’: What Price for Carbon?

The revised Renewable Fuels Standard (RFS2) mandates that cellulosic biofuels be part of the liquid transportation fuel mix and contribute to reducing our carbon footprint. Unfortunately, since no commercial cellulosic biorefinery exists and cellulosic biomass production is typically smaller scale than conventional crop production, limited knowledge exists of the actual costs of producing cellulosic biomass and converting it to cellulosic ethanol. Understanding of the implications of RFS2 requires a better understanding of the economics of producing cellulosic ethanol. We use the Biofuel Breakeven model (BIOBREAK), a simple long run breakeven model that represents the feedstock supply system and biofuel refining process, along with estimates of the potential reduction in carbon emissions from biofuels relative to conventional fuels, to derive the implicit carbon price (or carbon credit) needed to sustain a biomass market and cellulosic ethanol industry. We evaluate BIOBREAK under different oil prices, the RFS2 mandate, and with and without other biofuel incentives.Environmental Economics and Policy, Resource /Energy Economics and Policy, Biofuels, Biomass, Cellulosic Ethanol, RFS2, Carbon,

Valorisation of lignin – Achievements of the LignoValue project

Lignocellulosic biorefinery for production of biofuels, materials and chemicals requires valorization of all fractions including lignin. As a consequence of its poly-aromatic structure, lignin potentially serves as a source for aromatic chemicals. The developed biorefinery concept of the LignoValue project comprises two major steps: (1) Organosolv fractionation of wheat straw and willow into (hemi)cellulose and high purity lignin. (2) Further conversion of the isolated lignin via catalytic pyrolysis, supercritical depolymerization and partial hydrodeoxygenation (HDO) into different components like low molecular phenolic compounds, wood adhesives and fuel additives. The cellulose fraction resulting after organosolv fractionation is effectively hydrolysed by enzymes for biofuel production. Quality assessment of the liberated lignins shows interesting characteristics for follow-up chemistry such as high purity, relatively low molar mass and polydispersity. Catalytic pyrolysis in a fluidised bed at 400-500°C was found to convert organosolv lignin in 35-55% phenolic oil, 10% identified monomeric phenolic compounds, 10-20% water, 5-20% gas and 35-55% char. Supercritical depolymerisation of lignin in carbon dioxide based solvents resulted in a similar spectrum of products, however, at a lower temperature (ca 300°C) but at higher pressures. In both thermochemical processes the use of promotors or catalysts lead to an improved yield of the target monomeric aromatic products. Also the residual char fraction shows interesting properties for use in bio-char applications. Catalytic semi-continuous HDO of lignin in hydrogen atmosphere can be manipulated to yield both light oils or heavy oils as potential additives to fuels. Suitable catalysts were found to convert depolymerised lignin to phenolic oils in high yields. In this process no char formation is observed. The lignin oils were successfully tested on lab scale as partial substitution of phenol in resins for gluing wood panels. The LignoValue concept is critically reviewed in a techno-economic analysis demonstrating the potential for further commercial development and adoptation of this innovative biorefinery process in Europe
