摘要

The drilling industry relies heavily on synthetic additives that contribute to environmental degradation, material inefficiencies, and economic strain particularly in resource-limited regions. This review coins the term Culinary Waste Materials (CWMs) for the first time and proposes CWMs as a circular and sustainable alternative class of drilling fluid additives, derived from widely available agri-kitchen residues such as such as potato peels, okra mucilage, banana stems, and rice husk ash etc. Rich in biopolymers such as cellulose, pectin, lignin, and starch, CWMs demonstrate multifunctionality in enhancing fluid viscosity, reducing filtrate loss, and mitigating shale swelling. The paper presents a structure–function-based mechanistic analysis of CWMs, connecting their chemical composition to performance outcomes; an area largely overlooked in existing literature. A novel Multifunctionality and Field Viability Index (MFVI) is introduced to rank CWMs based on operational, environmental, and economic criteria. Additionally, a qualitative techno-economic assessment outlines four practical deployment models suited for both centralized and decentralized industrial contexts. By converting biodegradable waste into value-added fluid additives, this review offers a pathway to embed circular economy principles into drilling operations and supports broader transitions toward sustainable industrial practices aligned with SDGs 9, 12, and 13.
