Article Synopsis
- Composting is an eco-friendly way to manage biodegradable waste, which makes up almost half of municipal solid waste (MSW), and can be improved by adding char from MSW pyrolysis.
- The study tested different amounts of MSW char (0%, 2.5%, and 5%) on vegetable waste compost, revealing that higher char levels led to better thermophilic temperatures, nutrient availability, and overall compost quality.
- The results showed significant improvements in nutrient concentrations and reductions in volatile solids and heavy metals, especially with 5% char, demonstrating that using MSW char in composting enhances sustainability in waste management.
Article Synopsis
- - Plant mineral nutrition is crucial for crop productivity and human health, with soil acidity affecting nutrient availability and influencing plant growth, particularly the importance of calcium (Ca) in various biological processes.
- - Soil acidification results from factors like cation leaching and fertilizer use, decreasing the accessibility of essential nutrients (N, P, K, Mg, Ca) and negatively impacting global crop production.
- - Emerging technologies such as nanotechnology, genetic engineering, and genome sequencing show promise in improving Ca delivery to plants, developing acid-tolerant crops, and managing nutrient stress, aiming to boost crop yields while reducing environmental and economic drawbacks.
The bioconversion of Parthenium hysterophorus was performed through rotary drum composter and examined the mechanism of humification and heavy metals immobilization in the process. The 20th day compost contains a significant increase in humic substances of 28.7% compared to the initial day mix.

A numerous works have been conducted on the complete eradication of this weed, but due to the residuals exists in soil, the weed re-grows. Current study therefore aims at examining the transformation of this weed by an in-vessel composting approach (rotary drum composter) and the evaluation of toxicity characteristics using Vigna radiata and Allium cepa as bioindicators.

A three-step procedure was followed to identify the CSFs in MSWM. A conceptual structural equation model (SEM) was developed using cluster groupings of the identified CSFs to show their interrelationships.
