The Correct Option is A
Solution and Explanation
Concept:
Potato processing (chips, fries, flakes) generates a significant amount of byproduct waste.
• Solid Waste: Includes peels, trimmings, and rejected whole potatoes.
• Processing: Peeling is the first major industrial step, using steam, lye, or abrasion.
Step 1: Analyzing the peeling step.
Industrial peeling can remove between 10% to 15% of the total potato weight. In some processes like steam peeling, the loss can be even higher.
Step 2: Quantifying the solid waste.
Among the solid fractions, the outer skin (peel) is the most consistent byproduct. Tons of peels are generated daily by large-scale potato chip factories.
Step 3: Clarification on waste types.
Waste water is "liquid waste," while the question specifically asks for "solid waste." Potato peels constitute the largest single component of the solid waste stream. Final Answer: (A)
