Perspectives on the utilization of waste fat from beef cattle and fowl for biodiesel production in Mexico

Abstract

The purpose of this research was to perform a preliminary inventory of the waste fat generated from beef cattle and fowl in Mexico that could be used for biodiesel production. Additionally, the CO 2 emissions reduction that could be achieved by using the potential biodiesel to replace an energy-equivalent amount of fossil diesel was assessed. Based on national reports for the year 2014, it was estimated that the non-edible fat from beef cattle and fowl annually generated in Mexico is sufficient to produce 216.0 kt of biodiesel, which would furnish 8379 TJ. This amount is equivalent to 1.5% of the energy annually consumed in Mexico as fossil diesel for road transport. The potential 216.0 kt of animal fat-based biodiesel that can be produced annually could replace 198.3 kt of fossil diesel and thus allow a reduction in the WTW (well to wheels) emissions of 592.3 kt CO 2 , which represents 1.5% of the WTW CO2 emitted from the combustion of the fossil diesel used for road transportation in Mexico in the year 2014.

Utilizing Waste Cooking Oil for Sustainable Biodiesel Production: A Comprehensive Review

“…Neem seeds contain 20-30% oil, primarily unsaturated fatty acids, making it suitable for biodiesel [21].…”

“…A free fatty acid content exceeding 1%w/w leads to the production of soap, complicating product separation (glycerol) and reducing biodiesel yield. Given the higher water content in waste cooking oil, the hydrolysis reaction intensifies while the formation of esters diminishes simultaneously [21][22][23][24][25][26][27][28][29][30][31]. Hence, the supercritical methanol approach is adopted to address this issue, as water exerts a minimal impact in this method.…”

Türkiye için hayvansal atık yağlarından biyodizel üretiminin tekno-ekonomik analizi ve çevresel etkilerinin hesaplanması

“…Hayvansal atık yağlar biyodizel üretimi için ideal hammaddelerdir. Atık yağların hammadde olarak kullanılması atık yönetimine yardımcı olmasının yanında bertaraf edilme problemini de ortadan kaldırır [21][22][23]. Atık olarak sınıflandırılan yağların atık yönetimi, ülkenin kalkınması ve çevresel öncelikler için büyük önem arz etmektedir [9].…”

In Focus: Biotechnology and chemical technology for biorefineries and biofuel production

“…This In Focus issue includes two papers on biodiesel production. Firstly, Chavarria‐Hernandez et al analyzed the potential biodiesel production in Mexico using residual animal fats, specifically beef cattle and fowl. They concluded that the reuse of these and other residual fats could contribute to the energy transition, committed to the elimination of fossils fuels, and also avoid the adverse effects of contamination and damage to health through inadequate disposal of residual fats and fowl.…”
