“…This mode of operation has caused environmental problems due to generation of greenhouse gases, such as methane, brought on by anaerobic digestion, as well as the consumption of large amounts of water, not always plentiful at the processing site. Discarding wstewater from decortication has caused pollution of waterways as well as noxious effects on the aquatic fauna (Terrapon-Pfaff, 2012). In China, where sisal cultivation is mechanized and technically advanced, decorticators are similar to those in Tanzania, but their design is more modern, the units being more compact and efficient.…”

“…Assessment of environmental risks, social and rural development and food safety are based on the selection of sustainability criteria of the Roundtable on Sustainable Biofuels [RSB] that defines twelve principles based on aspects of social and environmental sustainability (RSB, 2011). It was selected six principles: greenhouse gas emissions, water use and quality, biodiversity, soil health, social and rural development and food security, as used by Terrapon-Pfaff et al (2012).…”

“…Decortication is done in large continuous feed machines using a large amount of water injected in the rotors, about 100 m³ per metric ton of dry fiber (Terrapon-Pfaff et al, 2012;Medina, 1954). This facilitates the removal of traces of parenchymal tissue, and improves the quality of the sisal fiber produced.…”

This work evaluates the potential of co-products from sisal fiber extraction and of plant residues at the end of the productive life cycle and their upgrading into bioproducts and biofuels, focus on Brazil, and, specifically on the Sisal Identity Territory in the state of Bahia. Sisal co-products and residues are identified and quantified; Environmental and socio-economic indicators are applied. Energy potential and bioproducts from sisal in Brazil have been studied in universities and research centers, but not sufficiently quantified, so the scientific bases for this purpose are still limited. Considering an annual sisal fiber production in Brazil at 100,000 MT, and a 4% yield from the fiber extraction process, an estimated 2.4 million metric tons of products are thus generated by the defibering process, consisting of pulp, sisal tow, and juice. Furthermore, an estimated 900,000 metric tons per year of residual biomass from the stems at the end of the 10-year productive cycle is produced and presently left to rot in the field.

“…Tanzania's sisal fibre production has increased significantly starting from the nineties (Brenters & Romijn, 2003) (Terrapon-Pfaff, et al, 2012. Reasons are, among others, a request for sustainable materials and the funding of a public-private Tanzania Sisal Board that supports the privately owned sisal estates.…”

“…One 300 kW pilot facility have been installed in the Tanga region (Muthangya, et al, 2009). Furthermore, it has been estimated that up to 102 GWh of electricity could be generated in Tanzania each year producing biogas from sisal wastes, equivalent to about 3% of the country current power production (Terrapon-Pfaff, et al, 2012). This electricity could be used both to power the sisal production activities and to provide energy services to the population.…”

Low‐cost sustainable biomass availability in the European Union may not be able to meet increasing demand; exploring the option of importing biomass is therefore imperative for the years to come. This article assesses sustainable biomass export potential from Brazil, Colombia, Indonesia, Kenya, Ukraine, and the United States by applying a number of sustainability criteria. Only biomass types with the highest potential are selected, to take advantage of economies of scale, e.g. pulpwood, wood waste, and residues in the United States, and agricultural residues in Ukraine. This study found that, except for the United States, pellet markets in the sourcing regions are largely undeveloped. The export potential depends strongly on pellet mill capacity and assumed growth rates in the pellet industry. Results show that the United States, Ukraine, Indonesia, and Brazil offer the highest biomass export potential. In the Business As Usual 2030 scenario, up to 204 PJ could potentially be mobilized; in the High Export scenario this could increase to 1423 PJ, with 89% of the potential being available for costs ranging from 6.4 to 15 €/GJ. These potentials meet the European Commission requirements for a 70% reduction in greenhouse gas emissions set in the Renewable Energy Directive. The total export potentials do not reflect the net possible import potentials to the European Union, as biomass could be imported to other countries where there is a demand for it, where less strict sustainability requirements are applied, and which are proximate to the sourcing regions, notably South Korea, Japan, and China. © 2018 The Authors.
