The organic wastes of plant origin and, in particular, those coming from sources related to tourism activities, such as those generated from golf courses and touristic coasts, constitute an increasing concern due to the rise in their production and their unsuitable management. Thus, this work aimed to assess the use of different composting strategies to manage these specific green wastes, such as grass clippings and pruning waste from a golf course and marine plant debris, mainly from posidonia (Posidonia oceanica L.). To this end, two composting scenarios were established: the first only considered green wastes in the composition of the composting mixtures, and the second used sewage sludge as a co-composting agent. The temperature of the piles was monitored, and physicochemical and chemical parameters were also studied throughout the process. The results obtained showed that composting is a feasible method to manage and recycle this type of green waste, obtaining end products with suitable physicochemical and chemical characteristics. However, proportions of sea plant wastes in the composting mixture higher than 30% can compromise the fertilizing value of the final compost. Moreover, the use of an additional co-composting agent (sewage sludge) improved the characteristics of the end products obtained, provided that this co-composting agent had suitable initial characteristics.

不同来源绿色废物流的管理：不同堆肥情景的评估

植物来源的有机废物，特别是来自与旅游活动有关的来源的那些，如高尔夫球场和旅游海岸产生的那些，由于其产量增加和管理不当而引起越来越多的关注。因此，这项工作旨在评估使用不同的堆肥策略来管理这些特定的绿色废物，例如来自高尔夫球场的草屑和修剪废物以及主要来自 posidonia ( Posidonia oceanica) 的海洋植物残骸L.）。为此，建立了两种堆肥方案：第一种只考虑堆肥混合物组成中的绿色废物，第二种使用污水污泥作为共堆肥剂。在整个过程中对桩的温度进行监测，并研究理化和化学参数。获得的结果表明，堆肥是一种可行的方法来管理和回收此类绿色废物，获得具有合适理化和化学特性的最终产品。然而，堆肥混合物中海洋植物废物的比例高于 30% 会影响最终堆肥的施肥价值。此外，使用额外的共堆肥剂（污水污泥）改善了所获得的最终产品的特性，
