Food Waste Management: Approaches to Achieve Food Security and Sustainability

Apple Academic Press eBooks (2023)

Afnan Ashraf Syed Anam Ul Haq Shabir Hassan Shakeel Ahmad Bhat Shahid Qayoom

Food waste management (WM) is one of the prime concerns related to food security and sustainability. Eradication of hunger is one of the important goals of the United Nations sustainable development program. However, the ever-increasing population across the world is hindering the achievement of this goal since the population is expected to be 10 billion by 2050. Not only this, the worldwide problem of food wastage is taking its toll on sustainability, food security, and food safety. Food losses and waste indirectly cost the environment since food production is resource-intensive, which consequently leads to environmental stress, causing water and air pollution, degradation, depletion of soil and green-house gases (GHGs) produced through food production, transportation, conveyance, and WM processes. As a result of these growing pressures, social, and economic issues regarding food waste are being recognized as a core problem for states, scholars, non-governmental organizations, companies, and the general public. Therefore, this chapter deals with the different approaches of sustainable and secure management of food waste that can definitely help us secure the present as well as the future to tackle the existing crisis of food all across the globe.

Modelling for Collective Effect of Muffler Geometric Modifications and Blended Microalgae Fuel Use on Exhaust Performance of a Four-Stroke Diesel Engine: A Computational Fluid Dynamics Approach

SAE International Journal of Advances and Current Practices in Mobility (2019)

Sumit Kanchan Rajesh Choudhary Chavagani Brahmaiah Shahid Qayoom

<div class="section abstract"><div class="htmlview paragraph">Engine performance significantly depends on the effective exhaust of the combustion gases from the muffler. With stricter BSVI norms more efficient measures have to be adopted to reduce the levels of emissions from the exhaust to the atmosphere. Muffler along with reducing the engine noise is intended to control the back pressure as well. Back pressure change has a significant effect on muffler temperature distribution which affects the NO<sub>x</sub> emission from the exhaust. Many research communications have been made to reduce the exhaust emissions like HC, CO and CO<sub>2</sub> from the exhaust by using different generation biofuels as an alternative fuel, yet they have confronted challenges in controlling the NO<sub>x</sub> content from the exhaust.</div><div class="htmlview paragraph">This work presents the combined effect of Muffler geometry modifications and blended microalgal fuel on exhaust performance with an aim to reduce NOx emission form a four-stroke engine. In this exertion, the computational fluid dynamics model is developed to analyze the effect of muffler geometry modification on vital exhaust parameters of an engine. The engine is powered with a blend of chlorella microalgae and diesel. The engine used for testing is a four-stroke diesel, water-cooled, SOHC engine. The muffler geometry such as Chambered Elliptic (CE), and Turbo Elliptic (TE) are designed for study. The reference for designing the mufflers in CREO was published literature and company product blueprints. The combined effect of muffler geometry modification and blended microalgal fuel use on back pressure, chamber temperature, pressure and velocity distribution are deliberated.</div><div class="htmlview paragraph">The result shows that the chambered elliptic muffler using B5 (5% Algal fuel) developed significantly less exhaust temperature, whereas the gas density is more in case of turbo elliptic muffler using B20 (20% Algal fuel). Finally, the velocity is slightly higher in the case of Turbo Elliptic (TE) muffler using B20 blend. Significant decrease in back pressure was noted for B20 blended fuel in case of TE over CE. The exhaust temperature was notably reduced in all B5 blends for all muffler’s geometries created. The work also aims to explore the effect on NOx emissions by analyzing the use of the combined effect of microalgae fuel and muffler geometry modifications on exhaust parameters by controlling the back pressure in the muffler. Almost no research is reported in this [<span class="xref">1</span>] field of work for microalgal fuels which is the objective of this work.</div></div>

Performance and Emission Characteristics of Thumba Oil Based Biodiesel on Diesel Engine: A Comprehensive Review

Asian Journal of Water Environment and Pollution (2018)

Shahid Qayoom Sumit Kanchan

Nowadays, the whole world is facing the problems of lack of fossil fuels and the rise of emission level in automobiles like carbon dioxide, carbon monoxide etc. In order to prevent the whole world from these problems, a number of research developments are taking place to change the concept of using only fossil fuels by displaying some new alternative fuels to the market so that this dependence on fossil fuels can be reduced. For most of the countries in the world, there are limitations of petroleum-based fuels. In other words, the petroleum-based reserves are limited to certain countries. Therefore, those countries which are totally dependent on import of crude oil have to go through many crises or intense difficulties. Hence it becomes very important to develop some alternative fuels, which could be easily obtained from many available resources like vegetables etc. Biodiesel is nowadays considered as the most effective, renewable and environmentally friendly fuel in place of diesel. While selecting the sources for extraction of biodiesel, the maximum focus is towards non-edible oils like Thumba, cotton, mahua oil etc., instead of edible oils like sunflower, palm, soybean oil etc., to reduce affecting food security. This review, therefore, displays various characteristics like performance and emission characteristics while using Thumba oil biodiesel in a diesel engine. Among highlights, this review covers properties of Thumba oil and Thumba oil treatment methods as well. In this review paper, researchers indicated that Thumba biodiesel reduces various pollutants like carbon monoxide (CO), hydrocarbon (HC), etc. related to diesel. It also covers that among all blends, preheated B20 Thumba biodiesel blend is having better emission and performance characteristics.
