Development of DYNAMIX Policy Mixes - Deliverable 4.2, revised version, of the DYNAMIX project

This report documents the development of the initial dynamic policy mixes that were developed for assessment in the DYNAMIX project. The policy mixes were designed within three different policy areas: overarching policy, land-use and food, and metals and other materials. The policy areas were selected to address absolute decoupling in general and, specifically, the DYNAMIX targets related to the use of virgin metals, the use of arable land and freshwater, the input of the nutrients nitrogen and phosphorus, and emissions of greenhouse gases. Each policy mix was developed within a separate author team, using a common methodological framework that utilize previous findings in the project. Specific drivers and barriers for resource use and resource efficiency are discussed in each policy area. Specific policy objectives and targets are also discussed before the actual policy mix is presented. Each policy mix includes a set of key instruments, which can be embedded in a wider set of supporting and complementary policy instruments. All key instruments are described in the report through responses to a set of predefined questions. The overarching mix includes a broad variety of key instruments. The land-use policy mix emphasizes five instruments to improve food production through, for example, revisions of already existing policy documents. It also includes three instruments to influence the food consumption and food waste. The policy mix on metals and other materials primarily aims at reducing the use of virgin metals through increased recycling, increased material efficiency and environmentally justified material substitution. To avoid simply shifting of burdens, it includes several instruments of an overarching character.

Del bodegón a la basura. Representaciones de alimentos en la historia del arte desde la perspectiva de la fotografía contemporánea

El artículo habla de la representación de alimentos en la Historia del Arte; estudia porqué las representaciones de comida tradicionalmente han sido consideradas como un género menor y plantea la hipótesis de su revitalización en el mercado del arte contemporáneo a través de la fotografía. Mediante el análisis de imágenes de comida en diferentes épocas, el texto explica que los bodegones casi siempre han sido símbolos de la superabundancia, presentando fundamentalmente alimentos, y en algunas ocasiones desperdicios. Continúa con la idea de que las sobras en las antigüedad eran orgánicas y sin embargo, en la actualidad los still life se han convertido en representaciones de basura, de desechos, y desperdicios en todas sus acepciones. El texto demuestra, mediante el análisis de algunas obras contemporáneas fotográficas, que el tema de la comida hoy es mucho más relevante de lo que la crítica de arte argumentaba en el pasado. Las imágenes de objetos conforman un sistema de representación y significado en continua evolución que es el reflejo de nuestra cultura. Estas fotografías nos hablan de sociología, política y economía mostrándonos en la actualidad el impacto que está sufriendo el medioambiente debido a nuestras rutinas cotidianas.

Soil-less systems vs. soil-based systems for cultivating edible plants on buildings in relation to the contribution towards sustainable cities

Food production and consumption for cities has become a global concern due to increasing numbers of people living in urban areas, threatening food security. There is the contention that people living in cities have become disconnected with food production, leading to reduced nutrition in diets and increased food waste. Integrating food production into cities (urban agriculture) can help alleviate some of these issues. Lack of space at ground level in high-density urban areas has accelerated the idea of using spare building surfaces for food production. There are various growing methods being used for food production on buildings, which can be split into two main types, soil-less systems and soil-based systems. This paper is a holistic assessment (underpinned by the triple bottom line of sustainable development) of these two types of systems for food production on buildings, looking at the benefits and limitation of each type in this context. The results illustrate that soil-less systems are more productive per square metre, which increases the amount of locally grown, fresh produce available in urban areas. The results also show that soil-based systems for cultivation on buildings are more environmentally and socially beneficial overall for urban areas than soil-less systems.

Análisis de tecnologías eco eficientes para la disposición final de residuos sólidos en las empresas Coraseo S.A y Seacor S.A

Los residuos sólidos como consecuencia directa de las actividades humanas, han representado un reto desde sus inicios, de ahí se empezaron a desarrollar técnicas y prácticas para garantizar una adecuada gestión de los residuos, nuestros primeros ancestros encontraron en los botaderos a cielo abierto la solución más fácil para disponer los desechos de animales y residuos de comida en sitios cercanos a sus viviendas, por ejemplo, los griegos poseen registros de la inauguración del primer relleno municipal en la ciudad de Atenas hace más de 2000 años. La evolución de las culturas, la revolución industrial y el crecimiento poblacional acelerado han modificado no solo la composición sino también la cantidad de los residuos sólidos producidos, haciendo cada día más difícil su adecuada gestión debido a su alto grado de toxicidad, la ausencia de materiales biodegradables y su volumen, traduciendo esto en un gran impacto. El panorama no es muy alentador y los pronósticos emitidos por el Banco Mundial prevén que para el año 2025 los niveles mundiales de residuos sólidos urbanos alcanzaran 2,2 millones de toneladas por año. Basada en el interés por la adecuada gestión de los residuos y la disminución del impacto ambiental de las empresas Coraseo S.A y Seacor S.A, la presente investigación busca seleccionar la metodología y/o tecnología más apropiada teniendo en cuenta las condiciones económicas, logísticas y de infraestructura de la empresa y la comunidad involucrada. En primera instancia se estudió en profundidad el panorama empresarial y posteriormente se seleccionó un grupo de cuatro propuestas para la transformación y aprovechamiento de los residuos sólidos que fueron evaluadas a nivel económico, normativo, medio ambiental. Los datos analizados sugieren entre otras cosas, un robustecimiento del marco legal ambiental colombiano y mundial, una mayor colaboración económica de los organismos internacionales y las entidades bancarias y finalmente una reducción en los costos de las tecnologías disponibles para el aprovechamiento de los residuos sólidos, haría posible el sueño de las sociedades de gestionar efectivamente los residuos sólidos generando el menor impacto ambiental posible y en el caso del grupo empresarial Cordobés lograr innovar y emprender con un proyecto eco eficiente como el que se evaluó.

Food-borne pathogens and pig waste products - the spoke in the wheel?

Food-borne pathogens are present in normal healthy pigs and thus are also present in pig wastes and by-products. The presence of these pathogens can be viewed negatively (i.e. 'a spoke in the wheel') or as simply another issue that requires the adoption of appropriate guidelines and management procedures. A key component in the development of appropriate, effective guidelines and management practices is a solid basis of knowledge on which pathogens are present as well as the levels of these pathogens. This paper reviews Australian Pork Limited (APL) funded projects carried out in our laboratories that have provided a solid base of Australian data for the pig industry. These data will ensure that pathogens are not 'a spoke in the wheel' but rather an issue - like many others that confront the industry - that can be managed to ensure that there is no unacceptable risk to either public health or the environment.

Biohydrogen production from food industry waste by suspended and immobilized thermophylic bacteria

This work describes hydrogen production by anaerobic digestion of glucose, molasses and milk whey by 4 thermophilic Thermotoga strains. In the attached-cell tests, the biofilm support characterized by the highest specific surface resulted in the best H2 rate. All the Thermotoga strains examined (T. neapolitana, T. maritima, T. naphtophila, T. petrophila) could produce H2 from glucose, molasses and milk whey, both in suspended- and attached-cell tests. With all the three substrates, the best performances were obtained with T. neapolitana. Some tests were conducted out to select the optimal carrier for the attached-cell conditions. 4 types of carrier were tested: 3 sintered glass carriers and a ceramic one; the chosen carrier was Biomax.

Solid Waste Disposal: Independent Food Service Practices

Solid waste disposal is a major concern today. This study seeks to identify the current practices and attitudes of managers of independent food services toward solid waste management and the characteristics of food services which were most likely to be involved with a solid waste management program

Growing banana prawns in prawn farm settlement ponds to utilise and help remove waste nutrients.

To assess their utility for profitable wastewater bioremediation, banana prawns, Penaeus (Fenneropenaeus) merguiensis (de Man), were stocked at low densities (1 – 5 m-2) and grown without supplemental feeding in five commercial-prawn-farm settlement ponds (0.3 to 6.0 ha). The prawns free-ranged in the variously designed ponds for 160 to 212 days after stocking as PL15. Survival estimates ranged from 12% to 60% with production of 50 – 528 kg ha-1. Over 1150 kg of marketable product was produced in the study. Exceptional growth was monitored at one farm where prawns reached an average size of 17g in 80 days. Nutrients in water flowing into (8 - 40 ML d-1) and out of the settlement pond at that farm were assessed twice weekly along with routine water quality measurements. Only small differences in water qualities were detected between waters running into and out of this settlement pond. Total nitrogen levels gradually increased from 1 - 1.5 mg L-1 early in the season to over 3 mg L-1 towards the end of the season. Total phosphorus levels similarly rose from 0.1 - 0.2 mg L-1 to 0.3 - 0.4 mg L-1 in the middle of the season, but fell to 0.2 – 0.3 mg L-1 towards the end when approximately 12,000 prawns were harvested with a total weight of 175 kg. No significant differences (P > 0.05) were detected in the overall acceptability of prawns harvested from each of the 5 settlement ponds in small-scale consumer sensory analyses. The prawns from settlement ponds were rated similarly to banana prawns grown with commercial diets at two other establishments. Microbiological analyses of prawns from all farms showed bacterial levels to be well within food-grade standards and lower than prawns produced in a normal growout pond. These results demonstrate that high quality food grade banana prawns can be produced in these wastewater treatment systems.

Investigations into the potential for mixed cultures of banana prawns Penaeus merguiensis, sea mullet Mugil cephalus and rabbitfish Siganus nebulosus for bioremediation of aquaculture waste

To experimentally investigate the potential of mixed species polycultures for bioremediation of nutrient rich prawn farm effluent, a series of experiments was performed with banana prawns Penaeus (Fenneropenaeus) merguiensis, sea mullet Mugil cephalus and rabbitfish Siganus nebulosus to determine their compatibilities during particular life stages. Rabbitfish demonstrated a high tendency to prey upon banana prawn juveniles when no other food was available. Mullet of various sizes did not appear to prey upon banana prawn postlarvae (PL16) or juveniles in a fed or unfed environment. The study confirms the good potential for mullet and banana prawn polycultures.
