Storms generate large volumes of vegetative debris, which often require significant resources for timely collection and disposal. This abundant debris also holds great potential for recycling and reuse, diverting it from landfills and creating value in end-of-life materials. However, it is critical to collect and process the debris promptly (before significant decomposition occurs) to maximize its value. Unfortunately, current debris management practices overlook the varying material conditions of vegetative debris in different storm-affected areas, limiting the sustainable use of these valuable resources. To address these challenges, the Principal Investigators (PIs) of this this Excellence in Research (EiR) project propose to study and understand the changing organic conditions of storm vegetative debris over time and space and integrate this knowledge into a data-driven planning framework for post-storm debris management. By considering the evolving condition of vegetative debris across storm-affected areas, the proposed planning method will optimize debris collection resource allocation to enhance recycling and reuse of collected materials. The successful completion of this project will benefit society through the potential improvement of post-disaster debris planning, waste reduction, and the creation of valuable end-of-life materials. Additional benefits to society will be achieved through student education and training including the mentoring of two graduate students as well as mentoring of a post-doctoral scholar at Florida Agricultural and Mechanical University (FAMU) and mentoring of a graduate student at California Polytechnic State University.Large quantities of vegetative debris require significant resources for timely management. Vegetative holds substantial potential for recycling and reuse, reducing landfill waste and creating value in end-of-life materials. However, the decomposition of organic materials poses challenges to achieving sustainable utilization. Given the spatial variability due to storage conditions and geographic distribution, as well as the temporal changes during collection, temporary storage, and final use or disposal, it is crucial to consider both spatial and temporal aspects in informed sustainable disaster waste management planning. To address this challenge, the Principal Investigators (PIs) of this project propose to investigate and unravel the characteristics and evolution of storm-related vegetative debris in space and time, integrating this understanding into data-driven debris management planning to enhance recycling, reuse, and advance sustainable waste management practices. The specific research objectives are to 1) identify the temporal evolution of vegetative debris and model the dynamic decomposition potential of uncollected debris; 2) develop an agent-based modeling (ABM) simulation model of debris collection operations and compare the spatially extended temporal performance-driven approach with the temporal-only approach using the simulation model and material assessment model; and 3) develop a novel spatial-temporal sustainability-based planning methodology for debris recovery. The successful completion of this project could lead to a paradigm shift in post-disaster planning, transitioning from the conventional time-based framework to a novel extended time- and space-based framework to enable more effective and sustainable debris management. To implement the education and training goals of the project, the PIs plan to engage with the Educating Engineering Students Innovatively (EESI) program at FAMU to enhance learning of students underrepresented in STEM. In addition, the PIs plan to engage with local agencies and contractors to make research products more relevant to management practicesThis award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

风暴会产生大量的营养碎片，通常需要大量资源才能及时收集和处置。这种大量的碎片还具有回收和再利用，将其从垃圾填埋场转移并在寿命末材料中创造价值的巨大潜力。但是，至关重要的是，迅速收集和处理碎屑（在发生重大分解之前）以最大化其价值。不幸的是，当前的碎屑管理实践忽略了不同风暴影响地区的营养碎片的不同物质条件，从而限制了这些宝贵资源的可持续使用。为了应对这些挑战，这项卓越研究（EIR）项目的首席研究人员（PI）建议研究和了解随着时间和空间的变化，风暴营养碎片的有机状况不断变化，并将这些知识整合到数据驱动的计划驱动的计划框架中，以实现后疾病的碎片管理。通过考虑跨暴风雨影响区域的营养碎屑的不断发展的状况，提出的计划方法将优化碎片收集资源分配，以增强收集材料的回收和再利用。该项目的成功完成将通过潜在的改善后污点碎片计划，减少废物和创造有价值的寿命终止材料来使社会受益。将通过学生教育和培训来实现社会的其他好处，包括指导两名研究生，并在佛罗里达农业和机械大学（FAMU）指导一位博士后学者，以及在加利福尼亚理工大学的研究生指导的。营养具有巨大的回收和再利用，减少垃圾填埋场的潜力，并在寿命末材料中创造价值。但是，有机材料的分解给实现可持续利用带来了挑战。鉴于由于存储条件和地理分布而导致的空间变异，以及收集，临时存储以及最终使用或处置过程中的时间变化，考虑到知情的可持续灾难废物管理计划中的空间和时间方面至关重要。为了应对这一挑战，该项目的主要研究人员（PIS）建议调查和揭示与风暴相关的营养碎片在时空中的特征和演变，将这种理解纳入与数据驱动的碎屑管理计划中，以增强回收，再利用，再利用，并提高可持续的废物管理实践。特定的研究目标是1）确定营养碎片的时间演变，并模拟未收集碎片的动态分解潜力； 2）使用仿真模型和材料评估模型，开发了碎片收集操作的基于代理的建模（ABM）仿真模型，并将空间扩展的时间性能驱动的方法与仅时间的方法进行比较； 3）开发一种新型的基于空间可持续性的计划方法，用于碎片回收。该项目的成功完成可能会导致灾后计划的范式转变，从传统的基于时间的框架过渡到一种新颖的扩展时间和空间基框架，以使更有效和可持续的碎屑管理。为了实施该项目的教育和培训目标，PIS计划在FAMU与教育工程专业的学生（EESI）计划互动，以增强STEM中代表性不足的学生的学习。此外，PIS计划与当地机构和承包商互动，以使研究产品与管理实践奖更相关，反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响审查标准，被认为值得通过评估来提供支持。
