“…Nowadays, the concept has been extended to the formulation of a biobased economy that has been estimated to grow globally by 2020 to $250 billion in value ($77 bn at 2005, $125 bn at 2010) generating up to 380,000 jobs (120,000 at 2005, 190,000 at 2010) However, currently biobased goods replace just 0.2 % of petroleum-based goods, but alternatives exist for over 90 % of them [67,68]. The prospect for scaling up has enlivened both supporters and critics of the technology [49,50].…”

Grape wine is among the most important alcoholic beverages in the globe, with a continuously rising world demand, currently sizing at 25 billion litres. Such a large and heavily industrialised market calls for the maintenance of a steady production of raw materials to end products. Consequently, intensive cultivation of land, harvesting of the goods and manufacturing for the production of commercially available products are being implemented. Wine making is a timed, multistage process producing a large amount of organic and inorganic waste. It has been calculated that during cultivation and harvesting about 5 tonnes of solid waste are generated per hectare per year, while the winery wastewater varies according to the production size from 650,000 m 3 (Greece) to over 18,000,000 m 3 (Spain) per year. Conventional treatments of winery waste are becoming increasingly expensive, demanding significant amounts of effort, resources and energy for safe waste discharge. Therefore, the need to recycle, reuse and recover energy and valuable chemicals from winery waste and wastewater becomes apparent. Valorisation of winery waste is possible when introducing the concept of biorefinery, i.e. the use of winery waste as bioconversions feedstock in order to produce platform chemicals, biofuels, heat and energy.

“…Crop residues are obtained as a by-product of agricultural post-harvesting activities, usually from the processing of staple crops for domestic consumption and export (Perimenis et al, 2011;Mohammed et al, 2013). They include straw and husks of cereals such as rice, maize/corn, sorghum, and millet; peels and stalks of cassava and straw and pods from cowpea.…”

This study analyses ex-ante socio-economic impacts of biogas systems using a remote rural community in Ghana as a case study. An analysis was performed for a 300 m 3 bio-digester that relies on crop residue and animal manure as feedstock to produce methane gas for cooking using selected bioenergy economic and social indicators. With a 10 percent discount rate, a 30 year bio-digester lifetime and methane tariff starting at US$ 0.7/m 3 , the project will have a Net Present Value of approximately US$ 22,000, 16 year payback and an Internal Rate of Return of 11%. The project will create 4 full time unskilled labour positions during the investment year and 3 positions during operation years. Using methane from the bio-digester for cooking will displace approximately 170 tonnes of firewood per year and save the women in the community a total of 3,400 hours per year not fetching firewood. However, only 5% of households are willing to pay the base tariff of US$ 30 /m 3 with up to 60% willing to pay less than half the monthly tariff. To make tariffs affordable to rural households, there is the need for subsidy schemes from government or relevant agencies.

“…In turn, the increase in food prices creates an incentive to expand cropland for agricultural production. The release of carbon from expanding cropland for production of displaced agriculture products, known as the indirect landuse change effect, could negate the carbon benefits associated with biofuel programs and affect the biodiversity, the soil quality, and the natural resources in a certain region [28,29]. In other words, indirect effects are mainly market related effects; changing market prices of different products is the link between biofuel promotion and indirect effects [30,31].…”

Interdependencies between Biofuel, Fuel and Food Prices: The Case of the Brazilian Ethanol Market

2016

Abstract:Brazil is currently the world's largest sugar producer and exporter, as well as the world's largest producer and consumer of sugarcane ethanol as a transportation fuel. The growth of this market originates from a combination of government policies and technological change, in both the sugarcane ethanol processing sector and the manufacture of flex-fuel vehicles. In recent years however, ethanol production has been questioned due to its possible impact on food prices. The present paper aims to explore the impact of Brazilian ethanol prices on sugar and gasoline prices. The relationships between a times series of these prices are investigated using a Vector Error Correction Model (VECM), supported by Granger Causality tests. In addition, Impulse Response Functions (IRFs) and Forecast Error Variance Decompositions (FEVD) are computed in order to investigate the dynamic interrelationships within these series. Our results suggest that ethanol prices are affected by both food and fuel prices, but that there is no strong evidence that changes in ethanol prices have an impact on food prices.
