Abstract Developing optimal flame retardant polymer compositions that meet all aspects of a given application is energy and cost-intensive. To reduce the number measurements, we developed an artificial neural network-based system to predict flammability polymers from small-scale test data structural properties. The can ignition time, peak total heat release, mass residue after burning reference...

Stubble burning in Chile is a common practice used for the farmers but it causes nutrient losses, erosion and environmental pollution. An alternative to change this situation incorporation of crop residue improve soil quality. The objective research was compare effects oat stubble on chemical physical properties an Humic Haploxerands with rotation oat-wheat. A completely randomized experimental...

A layer of harvest residues from the previous crop can reduce wasteful evaporation from the soil surface and thereby increase the efficiency of use of limited water resources for agricultural production. The practice of harvesting sugarcane green and leaving crop residues in the field, as opposed to burning the residue, has been re-adopted in many sugarcane industries worldwide. However, a bett...

We present the results of a study on climate forcing effects replacing coal for power generation in United Kingdom (UK) with wood pellets produced northern Ontario, Canada. Continuous pellet production from two biomass sources were considered: fiber increased harvesting standing live trees (stemwood scenario) and harvest residue provided by ongoing operations (residue scenario). In both scenari...

The U.S. EPA State and Local Climate Change Program is unveiling the Emission Inventory Improvement Program Volume VIII: Estimating Greenhouse Gas Emissions, a revised guide for states conducting greenhouse gas emission inventories. The revised guidance is accompanied, for the first time, by the State Tool for Greenhouse Gas Inventory Development, a user-friendly inventory spreadsheet tool inte...

Crop residue burning directly contributes to environmental pollution and releases 149.24 million tonnes of carbon dioxide (CO2), over 9 monoxide (CO), 0.25 oxides sulphur (SOX), 1.28 particulate matter 0.07 black carbon. The paddy straw results in extensive impacts both on off farm, e.g. losses soil organic matter, nutrients, production productivity, air quality, biodiversity, water energy effi...

in this study the effect of different nitrogen source substrates on the amount of chitosan production by aspergillus niger was investigated. a. niger ptcc 5012 from the persian type culture collection (ptcc) was grown on soy bean, corn seed and canola residues at 30 °c for specified cultivation days under sterilized conditions. chitosan was extracted from the fungal mycelia using hot alkaline a...

The author provides an interesting one-dimensional ap­ plication of Essenhigh's bed combustion models to munici­ pal waste combustors. Some of the model's limitations are recognized when the author explains that this work only considers chemical heat release and that radiative and con­ vective heat release may be significant and should be con­ sidered as well. In the mid 1970s, I was part of a ...
