Ethanol Production, Food and Forests

Ethanol Production , Food and Forests

This paper investigates the direct and indirect impacts of ethanol production on land use, deforestation and food production. A partial equilibrium model of a national economy with two sectors and two regions, one of which includes a residual forest, is developed. It analyses how an exogenous increase in the ethanol price a ects input allocation (land and labor) between sectors (energy crop and...

Corn ethanol production, food exports, and indirect land use change.

The approximately 100 million tonne per year increase in the use of corn to produce ethanol in the U.S. over the past 10 years, and projections of greater future use, have raised concerns that reduced exports of corn (and other agricultural products) and higher commodity prices would lead to land-use changes and, consequently, negative environmental impacts in other countries. The concerns have...

Biofuels versus food: How much Brazilian ethanol production can affect domestic food prices?

Production of Ethanol and Biomass from Thin Stillage Using Food-Grade Zygomycetes and Ascomycetes Filamentous Fungi

A starch-based ethanol facility producing 200,000 m 3 ethanol/year also produces ca. 2 million m 3 thin stillage, which can be used to improve the entire process. In this work, five food-grade filamentous fungi, including a Zygomycete and four Ascomycetes were successfully grown in thin stillage containing 9% solids. Cultivation with Neurospora intermedia led to the production of ca. 16 g·L −1 ...

Ethanol Production from Maize

The production of fuel ethanol from corn grain is widely carried out in the US, with total current production at 7 billion gallons. This may soon reach 10 billion gallons or more. This chapter addresses the potential of fuel ethanol as an additional source of product based on utilization of the cellulosic (non-food) portions of maize, and in particular the pericarp, cobs, stalks and leaves of t...
