“…The residual water is concentrated to a semi-solid sugary material (molasse) that is mixed with dry pulp and sold as animal feed or sold directly for biogas production. However, most of the juice plants dispose the solid waste to a landfill or mix it with wastewater and discharge to neighboring rivers (e.g., Evrotas, Lakonia) causing serious problems in their ecosystems [93]. Whatsoever, high transportation costs, lack of disposal sites, and the accumulation of waste with high organic load in open dumps renders these practices economically unfavorable.…”

The Potential of Tree Fruit Stone and Seed Wastes in Greece as Sources of Bioactive Ingredients

2018

The inedible part (stones, husks, kernels, seeds) of the tree fruits that are currently processed in various regions of Greece constitutes a huge portion of the fruit processing solid waste that remains underexploited. In this review, the existing scientific background for the composition and content of fruit stone and seed in bioactive ingredients is highlighted for olives, stone fruits and citrus fruits that represent the economically most important tree crop products of the country. The content of bioactive compounds may vary considerably depending on the quality of the raw material and the treatment during processing. However, both the hydrophilic and the lipophilic fractions of the seeds contain significant amounts of the primary and the secondary plant metabolites. Among them, phytosterols and several types of polyphenols, but also squalene, tocopherols and some other terpenoids with a unique structure are of particular importance for the utilization and valorization of stones and seeds. Official and scholar records about the current management practices are also presented to highlight the dynamics of the Greek fruit sector. Prospects for the regionalization of fruit seed wastes, in line with EU-promoted Research and Innovation Strategies (RIS) for Smart Specialization are critically discussed.

“…Previous studies emphasises that industrial and agricultural activities, coupled with sewage waste, stand out as the primary culprits of global river pollution (Samanta, 2013;Arif et al, 2020;Karaouzas, 2016). However, the process of urbanisation attract migration who later become increasingly recognised as a significant contributor to pollution (Jafar et al, 2016;Qin & Liao, 2016;Md Hashim & Man, 2018;Wang et al, 2020).…”

River pollution is one of the major threats to the environment worldwide, especially in developing countries such as Malaysia. Although numerous actions, policies and efforts to alleviate river pollution, the issue continues to hurt Malaysia’s environmental sustainability. Based on the case study of the Inanam-Likas river basin situated on the western coast of the state of Sabah, in East Malaysia, this paper proposes an integration of a more inclusive approach toward communities in river management. This paper suggests the inclusion approach in river management by squatter communities who are residents along the riverbanks as part of the stakeholders alongside governmental and non-governmental agencies. As such, this study introduces this approach as a community-based to the river management policy facilitated by the local authorities and other relevant agencies. Without community support, effective mitigation strategies and relevant policy toward river management, river pollution will continue to threaten environmental sustainability.

“…These byproducts are usually treated as waste. OWW and OOWW are stored in evaporation ponds each season, creating risks of contaminating groundwater with organic loads, generating bad odors, etc. , OMSW is also stored in evaporation ponds and burned in co-generation plants.…”

This study evaluates the comprehensive valorization of the byproducts derived from the two-phase olive oil elaboration process [i.e., olive washing water (OWW), olive oil washing water (OOWW), and olive mill solid waste (OMSW)] in a closed-loop process. Initially, the microalga Raphidocelis subcapitata was grown using a mixture of OWW and OOWW as the culture medium, allowing phosphate, nitrate, sugars, and soluble chemical oxygen demand removal. In a second step, the microalgal biomass grown in the mixture of washing waters was used as a co-substrate together with OMSW for an anaerobic co-digestion process. The anaerobic co-digestion of the combination of 75% OMSW−25% R. subcapitata enhanced the methane yield by 7.0 and 64.5% compared to the anaerobic digestion of the OMSW and R. subcapitata individually. This schedule of operation allowed for integration of all of the byproducts generated from the two-phase olive oil elaboration process in a full valorization system and the establishment of a circular economy concept for the olive oil industry.
