Soluble bio-based substances (SBS) were isolated from the anaerobic digestate of the organic humid fraction of urban waste and from the compost obtained from a mix of digestate, gardening residues and sewage sludge. These were compared with a commercial Leonardite-based product for their effects on the growth and productivity of two Lantana species. The SBS were found more powerful than the Leonardite-based product in enhancing plant photosynthesis, growth and aesthetic effect, improving flower quality, and optimizing water use efficiency. Enhancement factors of plant performance indicators by SBS ranged from 1.2 to 3.3 relatively to the control plants, and from 1.3 to 2.4 relatively to plants treated with the commercial Leonardite product at equal applied dose. The results are in line with findings published for other case studies performed with horticultural and ornamental plants. They confirm that municipal biowaste is a viable feedstock to obtain specialty chemicals that can efficiently replace fossil sourced products in agriculture. Options for further development work are discussed.

从城市垃圾有机湿气部分的厌氧消化物中以及从消化物，园艺残留物和污水污泥的混合物中获得的堆肥中分离出可溶性生物基物质（SBS）。将它们与商业的基于伦纳石的产品对两个马their丹物种的生长和生产力的影响进行了比较。SBS被发现比基于Leonardite的产品更强大，可以增强植物的光合作用，生长和美观效果，改善花的品质并优化水的利用效率。通过SBS获得的植物性能指标的增强因子相对于对照植物为1.2到3.3，相对于以相同剂量施用市售Leonardite产品处理的植物，其提高因子为1.3到2.4。结果与针对园艺和观赏植物进行的其他案例研究的结果一致。他们证实，市政生物垃圾是获取特种化学品的可行原料，可以有效替代农业中的化石来源产品。讨论了进一步开发工作的选项。
