BACKGROUND Animal wastes are of particular environmental concern due to greenhouse gases emissions, odor problem, and potential water contamination. Anaerobic digestion (AD) is an effective and widely used technology to treat them for bioenergy production. However, the sustainability of AD is compromised by two by-products of the nutrient-rich liquid digestate and the fiber-rich solid digestate...

BACKGROUND Sugarcane is the most efficient crop for production of (1G) ethanol. Additionally, sugarcane bagasse can be used to produce (2G) ethanol. However, the manufacture of 2G ethanol in large scale is not a consolidated process yet. Thus, a detailed economic analysis, based on consistent simulations of the process, is worthwhile. Moreover, both ethanol and electric energy markets have been...

Biorefineries combine necessary technologies between biogenic raw material and the industrial intermediates and final products. The paper represents the providing code-defined basic substances (via fractionation for the development of industrially relevant product family trees). The main focus is directed on precursor-containing biomass with preference of the carbohydrate line, in particulary o...

The 2011 US Billion-Ton Update1 estimates that there are enough agricultural and forest resources to sustainably provide enough biomass to displace approximately 30% of the country’s current petroleum consumption. A portion of these resources are inaccessible at current cost targets with conventional feedstock supply systems because of their remoteness or low yields. Reliable analy­ ses and pro...

The growing demand for rayon and cellulosic products has resulted in the conversion of a number of kraft pulp mills into dissolving pulp mills in recent years. In fact, kraft-based dissolving pulp production fits well into the concept of an integrated forest biorefinery, in particular, the utilization of dissolved organics in the pre-hydrolysis liquor (PHL) for bio-materials and bio-energy purp...

one of the indicators of management and sustainability control of forest resources is the definition deforestation and degradation types. these factors hazard quantitative and qualitative of the iranian forests. in this study with integrated approach, different forms of forest degradation identified in the forest areas with a reviews of library resources and then investigation the degree of sta...

HIS PAPER REPORTS the application of ESF (College of Environmental Science and Forestry) Biorefinery concepts and technology in New York State industry. This is a planned application linking at least three industrial companies to reduce the time to practice. A wood-based biorefinery is being erected in New York. Identifying the strengths of the participating companies and required competencies ...

Hybrid bio-thermochemical based technologies have the potential to ensure greater feedstock flexibility for production of bioenergy and bioproducts. This study focused on bioconversion syngas produced from low grade technical lignin C2-/C4-carboxylic acids by Butyribacterium methylotrophicum. The effects pH, medium supplementation use crude were analyzed. At pH 6.0, B. methylotrophicum consumed...
