Towards the development of a biobased economy in Europe and India

India has emerged as a key player with a high potential to develop a biomass and biobased economy due to its large geographic size and the massive amounts of agricultural and non agricultural biomass produced. India has joined hands with Europe to synchronize its efforts to create and facilitate the development of a biobased economy in this country. This paper aims to examine common research and development actions between the European Union (EU) and India to facilitate the development of these biobased economies. As a base, a thorough study has been performed considering the biomass potential and current status of the bioeconomy in both the EU and India based on the distillation of a series of 80 potential recommendations. The recommendations were grouped into four major categories: (1) biomass production, (2) by-products/waste, (3) biorefineries and (4) policy, market, and value-added products. A questionnaire was designed and distributed to key stakeholders belonging to: academia, industry, and policymakers in both India and the EU. A total of 231 responses were received and analyzed, based on the key recommendations made for the essential research and development topics that are of prime importance to develop biobased economies in both the EU and India. The findings of this study suggest recognizing the value-added contributions made by biobased products such as: food, feed, valuable materials and chemicals in both regions. It is important to reduce the overall process costs and minimize the environmental impacts of such a biobased economy.

U.S. Federal Initiatives to Support Biomass Research and Development

This article provides a brief overview of federal initiatives in the United States to support biomass research, demonstration, and development. The interest in the biomass industry and U.S. federal efforts to spur development of, increased production of, and use of biopower, biofuels, and biobased products, collectively known as the "biomass industry", are discussed. A growing level of leadership from the executive branch of the federal government and support by the U.S. Congress are documented. Five important policy drivers that support this heightened emphasis on biomass for power, fuels, and products are identified and discussed. The current status of U.S. dependence on these renewable energy sources is briefly outlined. Federal biomass funding activity for the current fiscal year by the U.S. Department of Agriculture and the U.S. Department of Energy, two major federal participants in research, demonstration, and development for this industry, is briefly outlined. This funding commitment is placed into an overall context of total federal support for all research and development. Finally, the article suggests future market penetration targets for this industry, emphasizes the importance of infrastructure development necessary to support the industry's growth, and notes the payoff from such development for farmers, foresters, rural communities, and the environment.     

"Drink Milk for Fitness": The Cultural Politics of Human Biological Variation and Milk Consumption in the United States

Cow's milk is accorded a high cultural value in the contemporary United States. Its white color, association with the maternal and the pastoral, and repeated mention in the Bible add positive symbolic weight to this major national agricultural commodity. Thus, it comes as no surprise that influential policy-making institutions in the United States recommend milk consumption for all U.S. groups. This is despite variation in adult populations' abilities to digest milk, which has been documented by biological anthropologists. This article assesses various U.S. "stories" about milk consumption and its relationship to biological variation against the biological anthropological explanation of variation in lactase activity/lactose tolerance. Many of these serve as normalizing discourses that ultimately pathologize biological difference and may undermine the dietary traditions of some ethnic groups. In particular, the close relationship between government and the dairy industry leads to policies that fail to seriously consider variation in digestive physiology among the diverse U.S. populations.     

The Physical Economy of the United States of America

The United States is not only the world's largest economy, but it is also one of the world's largest consumers of natural resources. The country, which is inhabited by some 5% of the world's population, uses roughly one‐fifth of the global primary energy supply and 15% of all extracted materials. This article explores long‐term trends and patterns of material use in the United States. Based on a material flow account (MFA) that is fully consistent with current standards of economy‐wide MFAs and covers domestic extraction, imports, and exports of materials for a 135‐year period, we investigated the evolution of the U.S. industrial metabolism. This process was characterized by an 18‐fold increase in material consumption, a multiplication of material use per capita, and a shift from renewable biomass toward mineral and fossil resources. In spite of considerable improvements in material intensity, no dematerialization has happened so far; in contrast to other high‐income countries, material use has not stabilized since the 1970s, but has continued to grow. This article compares patterns and trends of material use in the United States with those in Japan and the United Kingdom and discusses the factors underlying the disproportionately high level of U.S. per capita resource consumption.     

Surfactants Based on Renewable Raw Materials

Under the European Commission's European Climate Change Programme, a group of experts studied the possibilities of using more renewable raw materials as chemical feedstock and assessed the related potential for greenhouse gas (GHG) emission reduction. Surfactants were among the products studied. Surfactants are currently produced from both petro-chemical feedstocks and renewable resources (oleochemical surfactants). Assuming, in a first step, that total surfactant production in the European Union remains constant until 2010, it was estimated that the amount of oleochemical surfactants could be increased from about 880 kilotons (kt) in 1998 to approximately 1, 100 kt in 2010 (an increase of 24%). This substitution reduces the life-cycle CO₂ emissions from surfactants by 8%; the theoretical maximum potential for total substitution is 37%. Because the surfactant market is expected to grow, the avoided emissions will probably exceed 8% of the current life-cycle CO₂ emissions from surfactants. If compared to the CO₂ emissions from the total industrial sector and, even more so, if compared to the total economy, the relative savings are much lower (0.02% to 0.09%). This leads to the conclusion that the increased production and use of biobased surfactants should be part of an overall GHG emission reduction strategy consisting of a whole range of measures addressing both energy demand and supply. This article also discusses policies and measures designed to increase the use of biobased surfactants.     

Toward a low-carbon and circular building sector: Building strategies and urbanization pathways for the Netherlands

Buildings are an important part of society's environmental impacts, both in the construction and in the use phase. As the energy performance of buildings improve, construction materials become more important as a cause of environmental impact. Less attention has been given to those materials. We explore, as an alternative for conventional buildings, the use of biobased materials and circular building practices. In addition to building design, we analyze the effect of urbanization. We assess the potential to close material cycles together with the material related impact, between 2018 and 2050 in the Netherlands. Our results show a limited potential to close material cycles until 2050, as a result of slow stock turnover and growth of the building stock. At present, end-of-life recycling rates are low, further limiting circularity. Primary material demand can be lowered when shifting toward biobased or circular construction. This shift also reduces material related carbon emissions. Large-scale implementation of biobased construction, however, drastically increases land area required for wood production. Material demand differs strongly spatially and depends on the degree of urbanization. Urbanization results in higher building replacement rates, but constructed dwellings are generally small compared to scenarios with more rural developments. The approach presented in this work can be used to analyze strategies aimed at closing material cycles in the building sector and lowering buildings' embodied environmental impact, at different spatial scales.     

Agroterrorism in the U.S.: key security challenge for the 21st century

Agriculture is one of the easiest sectors of the U.S. economy to disrupt, and its disruption could have catastrophic consequences for the U.S. and world economies. Agriculture in the U.S. accounts for 13% of the current Gross Domestic Product (GDP) and provides employment for 15% of the population. It produces high-quality, cheap, plentiful food for domestic consumption and accounts for more than $50 billion in exports. The likelihood of terrorist acts interrupting the production, processing, and distribution of agricultural products is high: A number of different possible plant or animal pathogens could cause harm or loss of production, and even an act of agroterrorism that did not result in the destruction of foodstuffs or interruptions in the food supply could have a psychological impact. A number of recent unintentional events and epidemics have prompted the U.S. and other countries to provide resources to counteract contagious diseases and contain their impact, including increased funding to federal agencies that are responsible for protecting domestic agriculture. This article presents recommendations to protect agriculture, including changing the way agriculture is viewed on the federal level and increasing the resources to protect agriculture from terrorist attack.     

From John McCain to Abu Ghraib: Tortured Bodies and Historical Unaccountability of U.S. Empire

ABSTRACT   John McCain, once considered a "friend" of Vietnam because of his support for normalized relations with the United States, has since lost his standing. Claims to inhumane treatment and torture while a prisoner in the "Hanoi Hilton" have met with angry denials and calls for more attention to the humanitarian care that McCain and others received. Recent U.S. allegations of human rights abuses in Vietnam following the Abu Ghraib prison scandal have further strained relations, as have charges leveled against Vietnamese small-scale producers of dishonest trade practices. Drawing on these exchanges, I examine competing representations of Vietnamese wartime acts that have permeated the "normalization" process. Neoliberal rhetorics aimed at "saving" the Vietnamese economy and its allegedly blemished human rights record are countered by discourses and images that lay claim to a Vietnamese "tradition" of wartime compassion and humanitarianism that also demands U.S. historical accountability for imperial violence and its aftermaths.

Compositional Analysis and "Sources" of Pottery: An Ethnoarcheological Approach

One of the important assumptions of compositional analysis is that the elemental composition of an artifact reflects the source of the materials used to make it. Thus, pottery from a particular source will be chemically similar to the raw materials from that source. This "commonsense" assumption seems beyond dispute, but the fact that pottery is a mixture of clay, water, and often temper added by the potter, complicates the interpretation of compositional data from ceramics. This article examines the relationship between potters' behavior in obtaining and using raw materials, on the one hand, and the chemical composition of their finished pottery, on the other, by comparing the elemental composition of ethnographic pottery and raw materials from contemporary pottery-making communities in the Valley of Guatemala. The results of this research show that the relationship between pottery and its constituent raw materials is not as obvious as was first supposed. The article concludes with an alternative approach to compositional analysis that is more in line with the realities of real-world pottery production.     

Accuracy of radioanalytical procedures used to determine the biobased content of manufactured products

Radiocarbon analyses were used to determine the "biobased content" of a variety of diverse samples. The theoretical biobased contents of those samples were compared to the biobased content values obtained by radiocarbon analyses. Results of this work indicated that the radiocarbon analyses provided accurate (within +/-3%, absolute) biobased content values for the samples tested. It is not practical to examine the accuracy of the radiocarbon analyses for every possible type of sample matrix. However, based on analyses performed on various types of samples, every indication is that the analyses provide accurate and reliable results on the biobased content of liquid and solid materials.     

Economy‐wide Material Flow Indicators on a Sectoral Level and Strategies for Decreasing Material Inputs of Sectors

The article presents a method for the calculation of selected economy‐wide material flow indicators (namely, direct material input [DMI] and raw material input [RMI]) for economic sectors. Whereas sectoral DMI was calculated using direct data from statistics, we applied a concept of total flows and a hybrid input‐output life cycle assessment method to calculate sectoral RMI. We calculated the indicators for the Czech Republic for 2000–2011. We argue that DMI of economic sectors can be used for policies aiming at decreasing the direct input of extracted raw materials, and imported raw materials and products, whereas sectoral RMI can be better used for justifying support for or weakening the role of individual sectors within the economy. High‐input material flows are associated in the Czech Republic with the extractive industries (agriculture and forestry, the mining of fossil fuels [FFs], other types of mining, and quarrying), with several manufacturing industries (manufacturing of beverages, basic metals, motor vehicles or electricity, and gas and steam supply) and with construction. Viable options for reducing inputs of agricultural biomass include changes in people's diet toward a lower amount of animal‐based food and a decrease in the wasting of food. For FFs, one should think of changing the structure of total primary energy supply toward cleaner gaseous and renewable energy sources, innovations in transportation systems, and improvements in overall energy efficiency. For metal ores, viable options include technological changes leading to smaller and lighter products, as well as consistent recycling and use of secondary metals.     

Managing the Unmanageable: Elderly Russian Jewish Émigrés and the Biomedical Culture of Diabetes Care

In this article, we examine the apparent resistance of elderly Russian Jewish émigrés to the dominant U.S. biomedical model of diabetes treatment. Cultural competence on the part of medical professionals who make assumptions about Russian culture tends to be based on particularly American values of self-control and individual agency. The American consumer model of health care incorporating risk, individual responsibility, autonomy, and choice, when applied to elderly Russian Jewish émigrés, results in a reading of different values and choices as failed self-management or noncompliance. This article argues for a more reflexive understanding of U.S. biomedical culture as a replacement for the current "sound bite" model of cultural diversity.     

Sequential application of waste whey as a medium component for Kluyveromyces lactis cultivation and a co-feeder for lipase immobilization by CLEA method

Currently, much attention is paid to technologies which can be drivers of the circular economy across different sectors, in particular, to develop technologies for utilization or reusability of biocompatible materials from industrial waste. One of such is the milk whey, which is a cheap biobased raw material, the disposal of which is a major problem for the dairy industry. Our proposed and investigated technology is based on a continuous exploitation of the whey combining microbiology and biotechnology. Primarily, whey was used as a nutrition source for the cultivation of Kluyveromyces lactis with the aim to produce the targeted biocatalyst—lipase. During cultivation, the whey was transformed into the hydrolyzed form, which was further successfully applied as a protein feeder (external linker) for immobilization of lipase by cross-linked enzyme aggregate (CLEA) method. The first time use of whey as a co-feeder for immobilization of enzymes by CLEA method has shown promising results and increased the stability of lipases for temperature and organic solvents. Hydrolysis of rapeseed oil catalyzed with immobilized derivatives was obtained with 45–96% efficiency at non-optimized conditions. Additionally, the determined kinetic parameters indicated that the rate of p-nitrophenyl palmitate hydrolysis was not changed drastically after immobilization.

     

On the usage of agricultural raw materials – energy or food? An assessment from an economics perspective

Bioenergies are promoted across the globe as the answer for global warming and the chance to reduce dependency from fossil energy sources. Despite the fact that renewable energy sources offer the opportunity to reduce CO2 emission and present a chance to increase agricultural incomes, they also come along with some drawbacks that have been mostly neglected in the current discussion. This paper seeks to build a basis for discussing the impacts of the growing subsidization of bioenergy and the resulting usage competition of agricultural raw materials between foods and energy. To assess the usage competition and the subsidization of bioenergy, this article employs a welfare economics perspective associated with an emphasize on the construct of externalities. This will help to foster the discussion on the further subsidization of bioenergy, where funding for R&D on new ways of using non-food raw materials ought to play a significant role.

The Promises and the Challenges of Biotransformations in Microflow

The challenges of transition toward the postpetroleum world shed light on the biocatalysis as the most sustainable way for the valorization of biobased raw materials. However, its industrial exploitation strongly relies on integration with innovative technologies such as microscale processing. Microflow devices remarkably accelerate biocatalyst screening and engineering, as well as evaluation of process parameters, and intensify biocatalytic processes in multiphase systems. The inherent feature of microfluidic devices to operate in a continuous mode brings additional interest for their use in chemoenzymatic cascade systems and in connection with the downstream processing units. Further steps toward automation and analytics integration, as well as computer‐assisted process development, will significantly affect the industrial implementation of biocatalysis and fulfill the promises of the bioeconomy. This review provides an overview of recent examples on implementation of microfluidic devices into various stages of biocatalytic process development comprising ultrahigh‐throughput biocatalyst screening, highly efficient biocatalytic process design including specific immobilization techniques for long‐term biocatalyst use, integration with other (bio)chemical steps, and/or downstream processing.     

Assessment of sesame (<Emphasis Type="Italic">Sesamum indicum</Emphasis> L.<Emphasis Type="Bold">)</Emphasis> cake as a source of high-added value substances: from waste to health

The risk of exhaustion of natural resources and raw materials have given rise to emerging trends such as recycling of food waste. From the economical and ecological points of view, conversion of biowaste to high added value compounds has been getting great attention among the science and commercial entities. Due to their high-added value phytochemicals, agricultural and food residues have been a great significant to the researchers around the world. This study focuses on the valorisation of cake derived from sesame oil processing. If the very valuable non-nutrient phytochemicals in sesame cake are not evaluated properly, they would be consumed as just animal feed or fertilizers. They might be employed as antiaging (in pharmaceutical products), or free radical scavenger (in dietary supplements), or preservative additive against lipid oxidation (in fat containing food products). This review article aims to present pharmacological and therapeutic effects of sesame cake extract by pointing out its application in pharmaceutical, cosmetic and food industries.     

Practice and Politics in Japanese Science: Hitoshi Kihara and the Formation of a Genetics Discipline

This paper examines the history of Japanese genetics in the 1920s to 1950s as seen through the work of Hitoshi Kihara, a prominent wheat geneticist as well as a leader in the development of the discipline in Japan. As Kihara’s career illustrates, Japanese genetics developed quickly in the early twentieth century through interactions with biologists outside Japan. The interactions, however, ceased due to the war in the late 1930s, and Japanese geneticists were mostly isolated from outside information until the late 1940s. During the isolation in wartime and under the postwar U.S. Occupation, Kihara adapted to political changes. During wartime, he developed a research institute focusing on applied biology of various crops, which conformed to the national need to address food scarcity. After the war, he led the campaign for the establishment of a national institute of genetics and negotiated with American Occupation officers. The Americans viewed this Japanese effort with suspicion because of the rising popularity of the controversial theory of the Russian agronomist, Trofim Lysenko, in Japan. The institute was approved in 1949 partly because Kihara was able to bridge the gap between the American and Japanese sides. With Kihara’s flexible and generous leadership, Japanese genetics steadily developed, survived the wartime, and recovered quickly in the postwar period. The article discusses Kihara’s interest in cytoplasmic inheritance and his synthetic approach to genetics in this political context, and draws attention to the relation between Kihara’s genetics and agricultural practice in Japan.     

A Green and Sustainable Approach: Celebrating the 30th Anniversary of the Asymmetric l‐Menthol Process

Takasago has been devoted to producing l‐menthol since 1954, and our long history of manufacturing this important aroma chemical is reviewed here. The current asymmetric catalytic process had its 30th anniversary in 2013. Our l‐menthol process is considered carbon‐neutral, and, therefore, ‘green’ and sustainable. It uses renewable myrcene obtained from gum rosin as a starting material. In addition, the Rh‐BINAP (=2,2′‐bis(diphenylphosphino)‐1,1′‐binaphthyl) catalytic system is highly efficient. This pathway not only leads l‐menthol, but a variety of 100% biobased aroma chemical products as well. By measuring the ¹⁴C levels in a material, one can determine the percentage of carbon that is biobased. This biobased assay, described as the ratio plant‐derived C/fossil‐derived C, can clarify how renewable a product really is. This will be highlighted for several of Takasago's key aroma chemicals.
