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.

Colombia has strengthened regulations to ensure standardized food safety and quality in bovine slaughterhouses. To this end, the Ministry of Health and Social Protection designed to empower INVIMA, as the governing and coordinating authority for the operation of the Official Meat Inspection, Surveillance and Control System. This regulation aims to evaluate the technical conditions of infrastructures, slaughter processes and quality and safety assurance systems.

Article Synopsis
- Biochar, made from wood chips and bone-meat residues through pyrolysis at different temperatures, can enhance soil quality while recycling organic waste.
- The study focused on how different types of biochar influenced microbial communities and enzyme activities in two soil types for a year, revealing that production temperature and feedstock impact soil health and microbial diversity.
- It was found that bone-meat residues pyrolyzed at lower temperatures reduced microbial diversity but increased specific beneficial bacteria, while wood biochar improved enzyme activity related to nutrient cycling, particularly in acidic soils.

Extended-spectrum β-lactamases (ESBLs) are β-lactamase enzymes produced by Gram-negative bacterial pathogens that harbor the ESBL genes. In addition, most ESBL genes are plasmid-mediated and usually encode a broader spectrum of antimicrobial resistance, especially to penicillins, first-generation, second-generation, and third-generation cephalosporins, as well as monobactam, such as aztreonam. has become an opportunistic pathogen, especially in poultry, and has been implicated in zoonotic diseases that can be transmitted to humans, resulting in public health problems.

Tissue scarcity poses global challenges for corneal transplantation and public health. Xeno-keratoplasty using animal-derived tissues offers a potential solution, but its environmental and economic implications remain unclear. This study evaluated two xeno-keratoplasty procedures at a single institution: (1) native corneas (Option 1) and (2) tissue-engineered corneal scaffolds derived from slaughterhouse waste (Option 2).
