Assessment of Bio- Ethanol and Biogas Initiatives for Transport in Sweden
Assessment of bio- ethanol and biogas initiatives for transport in Sweden Background information for the EU-project PREMIA EU Contract N° TREN/04/FP6EN/S07.31083/503081 May 2005 2 Abstract This report is the result of an assignment on assessment of bio-ethanol and biogas initiatives for transport in Sweden, granted by VTT Processes, Energy and Environment, Engines and Vehicles, Finland to Atrax Energi AB, Sweden. The report of the assignment is intended to append the literature and other information used in the “PREMIA” project The work has been carried out by Björn Rehnlund, Atrax Energi AB, Sweden, with support from Martijn van Walwijk, France. The report describes the development of the production and use of biobio-ethanol and biogas (biomass based methane) as vehicle fuels in Sweden and gives an overview of today’s situation. Besides data and information about numbers of vehicles and filling stations, the report also gives an overview of: • Stakeholders • The legal framework, including standards, specifications, type approval, taxation etc. • Financial support programs. Public acceptance, side effects and the effect off the introduction of bio-ethanol and biogas as vehicle fuels on climate gases are to some extent also discussed in this report. It can be concluded that since the early 1990’s Sweden has had a perhaps slow but steadily increasing use of bio-ethanol and biogas. Today having the EC directive on promotion of bio bio-fuels and other renewable fuels in place the development and introduction of filling stations and vehicles has started to increase rapidly. From 1994 to 2004 the number of filling stations for bio-ethanol grew from 1 to 100 and during the year 2004 until today to 160 stations. -

Giant Miscanthus Establishment
Giant Miscanthus Establishment Introduction Giant Miscanthus (Miscanthus x giganteus), a warm-season perennial grass originating in Southeast Asia from two ornamental grasses, M. sacchariflorus and M. sinensis, is a popular candidate crop for biomass production in the Midwestern United States. This sterile hybrid is high yielding with many benefits to the land including soil stabilization and carbon sequestration. Vegetative propagation methods are necessary since giant Miscanthus does not produce viable seed. Field Preparation A giant Miscanthus stand first begins with field seedbed preparation. To provide good soil to rhizome contact, Figure 1. Rhizome segments. Photo credit: Heaton Lab. the seedbed should be tilled to a 3- to 5-inch depth. Soil moisture is critical to proper establishment for early stage time after the first frost in the fall and before the last one in germination. If working with dry land, prepare your field just the spring. If not immediately replanted in a new field, they prior to planting for optimal soil moisture. Good soil contact should be kept moist and cool (37-40º F) in storage. Ideal is also critical, so conversely, don’t till when the land is wet rhizomes have two to three visible buds, are light colored, and clods will form. Nutrient (NPK) and lime applications and firm (Fig. 1). Smaller rhizomes or those that are soft to should be made to the field as necessary before planting, the touch will likely have lower emergence. following typical corn recommendations for the area. Giant Miscanthus does not have high nutrient requirements once RHIZOME PLANTING established, but fields last for 20-30 years, so it is important Specialized rhizome planters are becoming available that adequate nutrition be present at establishment. -

Cassava Plant Guide
Plant Guide Food products: There are hydrocyanic glucosides CASSAVA (HCN) in all parts of the plant; these glucosides are Manihot esculenta Crantz removed by peeling the roots and boiling in water. Plant symbol = MAES The young tender leaves are used as a potherb, containing high levels of protein and vitamins C and Contributed by: USDA NRCS National Plant Data A. The leaves are prepared in a similar manner as Center spinach, while eliminating toxic compounds during the cooking process. Cassava flour is used to make cookies, quick breads, loaf breads, pancakes, doughnuts, dumplings, muffins, and bagels. Cassava extracted juice is fermented into a strong liquor called kasiri. It also can be concentrated and sweetened until it becomes dark viscous syrup called kasripo (casareep). This syrup has antiseptic properties and is used for flavoring. The peeled roots of the sweet variety are usually eaten cooked or baked. Livestock: Cassava leaves and stem meal are used for feeding dairy cattle. Both fresh and dried cassava roots are consumed by ruminants in different forms (chopped, sliced, or ground). Cassava bushes three to four months old are harvested as forage for cattle and other ruminants. Lincoln Moore. 2005 USDA NRCS Ornamental: One clone with variegated leaves is planted as an ornamental.

Evaluating the Environmental Impact of Corn Stover Collection for Biofuels Production Thesis Presented in Partial Fulfillment O
Evaluating the Environmental Impact of Corn Stover Collection for Biofuels Production Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University. By Asmita Khanal, B.E. Environmental Science Graduate Program The Ohio State University 2018 Master’s Examination Committee: Dr. Ajay Shah, Advisor Dr. Harold Keener Dr. Frederick Michel Dr. Shauna Brummet Copyright by Asmita Khanal 2018 Abstract Corn stover is the most readily available lignocellulosic feedstock for cellulosic biofuel production in the Midwestern U.S. Biofuels produced from corn stover could offset the environmental impact of fossil fuel combustion. Corn stover harvest for biofuels production removes potentially recyclable nutrients and carbon, increases the vulnerability of the soil to soil erosion, and produces emissions during harvest and collection due to operation and manufacture of the machinery, thus challenging the sustainability of the process. The main objective of this research was to evaluate the environmental impact of corn stover removal for biofuel production by first determining physical and compositional attributes of the corn stover in terms of dry matter, structural carbohydrates, lignin and nutrients, and then quantifying the environmental impact of corn stover collection for biofuel production. In 2016 and 2017, stover fractions below and above ear-level, and cobs contributed 42-56%, 31-38% and 13-18% to the total non-grain aboveground dry matter, respectively. Based on this dry matter contribution of the different fractions, three different corn stover removal scenarios were established: 1) removal of cobs, 2) removal of stover above ear level excluding cobs, and 3) removal of stover above half way between ground and ear level excluding cobs, to analyze the environmental impact in terms of greenhouse gases emissions in comparison to the base case scenario, i.e., no stover removal. -
