Abstract：
Global meat consumption is on a rise with around 253 million metric tons of meat produced globally in the year 2020. Because of the rise in population and change in food preferences, meat consumption trend is likely to continue. Meat production by animal slaughtering increases the slaughterhouse wastes in the form of both solid and liquid wastes. Although various technologies for slaughterhouse waste management are available in developed countries, the effective utilization of slaughterhouse waste management is still missing in developing countries like India. India plays an active role in the meat export business globally and stood 2nd in the world with a total export valuation of 2.89 billion US $ in the year 2020. In this context, this study presents a critical overview of the current technological advancements in the global slaughterhouse waste management including utilization of by-products and further, the prevailing slaughterhouse waste management of India is discussed. Finally, a sustainable slaughterhouse waste management strategy emphasizing circular economy and regulations improvements have been suggested for India to compete in this sector at global scale.
摘要：
全球肉类消费量正在上升，2020年全球肉类产量约为2.53亿吨。由于人口的增加和食物偏好的变化，肉类消费趋势可能会持续。动物屠宰的肉类生产增加了固体和液体废物形式的屠宰场废物。尽管在发达国家有各种屠宰场废物管理技术，在印度等发展中国家，屠宰场废物管理的有效利用仍然缺失。印度在全球肉类出口业务中发挥着积极作用，在2020年的总出口价值为28.9亿美元，位居世界第二。在这种情况下，这项研究提供了全球屠宰场废物管理的当前技术进步的关键概述，包括副产品的利用，讨论了印度现行的屠宰场废物管理。最后,印度建议采用可持续的屠宰场废物管理战略，强调循环经济和法规改进，以在全球范围内参与该行业的竞争。
