水稻是菲律宾的主要农作物，对该国的粮食安全至关重要。水稻种植的一个主要挑战是收获后秸秆的管理。由于用途有限，稻草目前被焚烧，或在某些情况下被并入严重的环境影响。然而，它可以成为可持续生物能源的重要原料，并支持菲律宾的能源获取。本研究是在菲律宾拉古纳省的一个1000 m3沼气中试厂进行的。这项研究的目的是开发商业模式，并评估其在改善能源获取、农业实践和增强当地水稻种植社区权能方面的潜力。开发了四种商业模式，反映了能源供应和需求的方法。这是通过对案例研究所在地的利益攸关方，包括农民、农业企业家、地方当局和决策者的访谈得出的。进行了多标准评估，以评价业务模式不同方面之间的协同增效和权衡。虽然所有商业模式都对环境、经济、特别是社会可持续性产生了积极的影响，但农业社区对提供可再生能源以外的更广泛生计惠益的方法表示最大的支持，如农业活动和创收的多样化。这表明，生物能源有可能为当地社区创造一个良性循环，以支持可持续发展。为了实现这一目标，必须对不同的可持续性标准采取全面和多层次的方法，以最大限度地提高能源技术以外的生物能源系统的效益并减轻其负面影响。
Rice is the main agricultural crop in the Philippines and central to the country's food security. One main challenge of rice farming is the management of the straw after harvest. With limited uses, the rice straw is currently burned or in some cases incorporated with significant environmental impacts. However, it can be an important feedstock for sustainable bioenergy and support energy access in the Philippines. The research was conducted around a 1000 m3biogas pilot plant in Laguna province, Philippines. The aim of this research was to develop business models and assess their potential for improving energy access, agricultural practices, and empowering local rice-growing communities. Four business models were developed, reflecting energy supply and demand approaches. This was informed by interviews with stakeholders, including farmers, agricultural entrepreneurs, local authorities, and policymakers in the case study location. A multi-criteria assessment was conducted to evaluate synergies and trade-offs between different aspects of the business models. While all business models provided positive environmental, economic, and in particular social sustainability impacts, the farming community showed the most support for approaches that provide wider livelihood benefits beyond renewable energy access, such as diversification of agricultural activities and income generation. This demonstrated that bioenergy has the potential to create a virtuous circle of benefits for local communities in support of sustainable development. To achieve this, it is essential to take a holistic and multi-level approach to the different sustainability criteria to maximise benefits and mitigate negative impacts of bioenergy systems beyond energy technology.
