This report explores green‑business upgrading for Archibald Zele, a South‑African SME operator running both logistics and clean‑energy businesses. His enterprise suffers from disconnected business lines, fossil‑fuel‑driven high operational costs, under‑monetised clean‑energy assets and resource waste caused by inefficient logistics operations. This article proposes a practical circular green‑logistics model: integrating clean‑energy hardware with delivery fleets, optimising supply‑chain workflows, and building local low‑carbon service branding. Requiring no drastic industrial overhaul, this solution brings commercial, environmental and social value, offering a replicable sustainable growth reference for grassroots logistics SMEs in South Africa.
