Case #1The Origins of the Negotiations on the 1989 Basel Convention

Transboundary shipments and disposal of hazardous waste became the focus of international concern in the early 1980s as many developed countries began implementing strict legislation on waste disposal. The high costs associated with this new regulatory action made alternatives, such as shipping toxic wastes to developing countries, appear more attractive and certainly less costly to the many industries in developed countries producing such wastes.

the ash was finally illegally dumped into the Atlantic and Indian oceans. News of the incident contributed to growing international concern that tightened regulations for hazardous waste disposal in developed countries had to be accompanied with international rules regulating trans-boundary movements of hazardous wastes.
