“…For example, research has reported the disease-suppressive properties of thermophilic compost and vermicompost on a wide range of phytopathogens, including Rhizoctonia, Phytophthora, Plasmidiophora brassicae, Gaeumannomyces graminis, and Fusarium species. Bio-composts have also proven effective in controlling arthropods and nematodes, improving overall soil health [42,44].…”

A comprehensive understanding of soil microbiome dynamics is imperative for bolstering sustainable agricultural productivity and devising effective soil management strategies. This study investigates the impact of leaf and other compost amendments on soil microbial richness and diversity. Metagenomic profiling techniques targeting 16S rRNA genes and Internal Transcribed Spacer (ITS) region were employed to examine the bacterial and fungal microbiome structure in both pre-plantation and post-harvest soils. The findings reveal a notable increase in beneficial bacterial and fungal genera in the soil amended with compost, including Bacillus, Nitrospira, Planctomyces, Myxococcus, Agromyces, Wallemia, Pichia, and Microascus. Conversely, pathogenic genera such as Corynebacterium, Burkholderia, Nocardia, Olpidium, Penicillium, Acremonium, and Alternaria exhibited higher abundance in soil amended with chemical fertilizers, highlighting the potential of bio-compost amendments in bioremediation and pathogen control. The post-harvest soil samples amended with leaf-based compost showed an increase of 116% in beneficial bacterial genera and a 21% increase in beneficial fungal genera, accompanied by a 59% and 60% decrease in pathogenic bacterial and fungal genera, respectively. In contrast, the chemical fertilizer amendment reduced beneficial bacterial and fungal genera by approximately 49% and 2%, respectively, while increasing pathogenic bacterial genera by about 132% in the post-harvest soil. The study underscores the significant impact of leaf-based bio-compost amendments on soil microbial richness, diversity, and overall soil health. Leaf-based bio-compost enhanced microbial diversity and functionality, fostering beneficial microorganisms that play pivotal roles in nutrient cycling, plant growth promotion, and strengthening soil ecosystem resilience.

“…The results of processing using biodiesel can serve as fuel substitute fuel (RDF) which is fuel produced from various types of waste such as waste, industrial waste or commercial waste. RDF can be used as a coal substitute [2]. The most obvious uses of the bio drying process are the decrease in odor, volume, and weight of waste, which can improve dental, transport and solid waste disposal at the time of large solid waste volumes.…”

The generation of solid waste around the world creates problems if not properly managed. The method of processing solid waste by burning or landfill is currently not optimal. The availability of land where the final processing (TPA) is critical, looking for a new TPA alternative will be difficult and expensive, especially in big cities. The processing of solid waste using bio drying technology has the potential to produce renewable energy and prevention of climate change. Solid waste processing products can serve as Refuse Derived Fuel (RDF), reduce water content of solid waste, meningkatkan kualitas lindi and increase the amount of recycled solid waste that is not completely separated from home. Biodrying technology is capable of enhancing the partial disintegration and hydrolysis of macromolecule organic compounds (such as C-Organic, cellulose, hemicellulose, lignin, total nitrogen). The application of biodrying has the potential to reduce greenhouse gas emissions such as carbon dioxide (CO2), methane (CH4), and dinitrooksida (N2O). These gases cause global warming.

Understanding the dynamics of soil microbiomes is crucial for sustainable agriculture and developing effective soil management strategies. This study investigates the impact of leaf-based compost and other organic waste bio-compost amendments on the microbial richness and diversity in soils using 16S rRNA metagenomic profiling. Our results revealed significant variation of the microbiome richness and diversity on soil due to the bio-composts amendment. Interestingly, the bio-composts amendment resulted in a pronounced enrichment of beneficial microorganisms such as Achromobacter, Agromyces, Bacillus, Clostridium, Nitrospira, Planctomyces, Pseudomonas, Steroidobacter, Streptomyces, Alicyclobacillus, and Bdellovibrio, known for their roles in nutrient recycling, plant growth promotion, and disease suppression. The presence of pathogenic bacteria such as Flavobacterium, Leptolyngbya, Balneimonas, Geobacter, Nocardia, and Mycobacterium, were higher in the chemical fertilizer-amended soil sample than the bio-composts amended soils, which indicated the bioremediation of pathogens due to bio-compost amendment. Moreover, it was also observed that the microbiome population of the cultivars were affected by the bio-compost amendments. Generally, the organic cultivars produced using bio-compost amendments had higher beneficial microorganisms and lower pathogens than the conventional produce with chemical fertiliser amendment. Thus, leaf-based compost and other organic-waste compost could be used as bio-organic fertilizer for healthy sustainable productivity.
