Disposal of fly ash in dumps is posing serious environmental problem causing air pollution, groundwater contamination, and loss of valuable land making it unproductive dumpsites. Cultivation of plants using bioremediation technique is looked upon as one of the sustainable remedial solution to these fly ash dumpsites. In recent years, researches on the plantation of bio-energy crops over the fly ash dumpsites is creating renewed interest, as it serves remediation along with distinct energy outcomes creating a win-win situation. The issue of the slow growth of plants, due to lack of nutrients and microbial activities is being resolved through advances in bioremediation research done in conjunction with organic matter, microbial inoculants, and inclusion of wastewater. New researches are being done with different plants and microbes in the matrix combination and use wastewater to supplement nutrients requirement to find eco-friendly & sustainable solutions. The present paper critically reviews the research on bioremediation and amendments with specific to bio-energy plantation on fly ash dumps.
将粉煤灰倾倒在垃圾场正造成严重的环境问题，导致空气污染、地下水污染以及宝贵土地的流失，使这些垃圾场失去生产力。利用生物修复技术种植植物被视为解决这些粉煤灰垃圾场问题的可持续补救方法之一。近年来，在粉煤灰垃圾场上种植生物能源作物的研究引起了新的关注，因为它在进行修复的同时还能产生独特的能源效益，创造双赢局面。由于缺乏养分和微生物活动导致植物生长缓慢的问题，正通过结合有机物、微生物接种剂以及纳入废水进行的生物修复研究进展来解决。目前正在对不同植物和微生物进行新的研究，探索基质组合并利用废水补充养分需求，以寻找生态友好且可持续的解决方案。本文对粉煤灰垃圾场上生物能源种植园的生物修复及改良研究进行了批判性综述。
