The study focused on Nigeria's polyurethane (PU) production process as a test case. Though it is currently insignificant when viewed from a global perspective, PU production in Nigeria is not eco‐friendly. Traditionally, PU is produced by reacting petro‐based polyol with a poly‐isocyanate, which is made from amines and phosgene and are currently imported into the country. These two materials are detrimental to the human health and environment, indicating that Nigeria's PU industries need to re‐examine their production inputs for environmental compliance. The objective of this study is to review the PU industry for nontoxic reagents that could be sourced locally vis‐a‐vis overcoming sustainable development (greening the economy) challenges in Nigeria. Non‐isocyanate polyurethane (NIPU) is preferred to petro‐polyurethane because, in comparison, NIPU has improved thermal and chemical resistance, porosity and water absorption, and is less toxic. Engaging local resources to produce PU is economically feasible; in addition, NIPU is relatively advantageous to human health and the environment. Aside from being economically feasible, production of NIPU in Nigeria has the propensity to greatly enlarge the growth of the existing PU industry to tremendous heights and contribute to diversifying and improving the overall economy.

为工业和环境可持续性绿色尼日利亚经济：聚氨酯生产作为测试案例

该研究以尼日利亚的聚氨酯 (PU) 生产工艺为测试案例。尽管从全球角度来看，目前它微不足道，但尼日利亚的 PU 生产并不环保。传统上，聚氨酯是通过石油基多元醇与多异氰酸酯反应生产的，多异氰酸酯由胺和光气制成，目前进口到该国。这两种材料对人体健康和环境都有害，这表明尼日利亚的聚氨酯行业需要重新审视其生产投入的环保合规性。本研究的目的是审查 PU 行业是否可以在当地采购无毒试剂，以克服尼日利亚的可持续发展（绿色经济）挑战。非异氰酸酯聚氨酯 (NIPU) 优于石油聚氨酯，因为，相比之下，NIPU 具有更高的耐热性和耐化学性、孔隙率和吸水性，并且毒性更小。利用当地资源生产聚氨酯在经济上是可行的；此外，泥普对人类健康和环境也相对有利。除了在经济上可行之外，尼日利亚 NIPU 的生产还有可能将现有 PU 行业的增长大幅扩大到巨大的高度，并有助于实现整体经济的多元化和改善。
