“…Analyzing the characteristics of initial materials in this research indicates lower OM (50.48 ± 3.1% d.m.) in comparison with the values reported in other countries, especially developed countries 31 – 33 . Difference among the reported values is generally related to the composition of compostable materials, which mainly arises from the implementation of separate collection systems and different efficiencies of material separation and processing systems in composting facilities 34 , 35 .…”

The main objective of this study was to investigate the effect of biochar on the composting process of the organic fraction of municipal solid waste (OFMSW) under real conditions. Different doses of biochar (1%, 3%, and 5%) were mixed with compost piles to evaluate the variation of temperature, moisture content (MC), organic matter (OM), carbon (C), nitrogen (N), C/N ratio, and heavy metal (HM) contents in comparison with the control treatment (with 0% biochar addition). The results of this study showed that the compost piles combined with different doses of biochar had higher MC. The use of biochar as an additive, even at low doses (1%), was able to increase the compost quality through the reduction of N losses during the composting process. The highest reduction of OM during the composting process was observed in the control pile (without biochar addition) by 48.06%, whereas biochar affected the biodegradability of OM and prevented the reduction of nutrients during the composting process under real conditions. The contents of HMs (Pb, Zn, Ni, Cd, and Cu) showed a significant reduction in all of the compost piles combined with biochar in comparison with the control treatment. Considering that in terms of all compost quality indicators, the piles combined with biochar can regarded as high standard product, the composts obtained from combining the OFMSW with different biochar doses have desirable features to be used as an amendment agent to improve agricultural soil quality.

“…Metals and radioactive waste are toxic to soil organisms and plants, and may reduce crop productivity. In Australia, Langdon et al (2019) studied risk assessment for organic pollutants in composted municipal solid waste in which they were able to categorize the risk levels into low, medium, and high based on human health. In another study, Gangwar et al (2019) investigated the impact of electronic waste on human health and reported the release of various toxic metals that cause air pollution.…”

Population growth and industrial development have led to an increase in urban solid waste globally. Collection and disposal of urban waste remain the biggest challenges that countries face at the moment. Proper management in various stages of production, storage, transportation, and disposal of waste can ensure minimal impact to human and environmental health. There are several tools for evaluating a waste management system; among these, life cycle assessment (LCA) is an important one. This article aims to evaluate the life cycle of waste management in the city of Rasht and prioritize decisions to develop its waste management system. To achieve this purpose, four waste management scenarios were designed. In addition, the life cycle cataloging of the scenarios was done using the IWM‐1 model in order to calculate the consumption of energy and also obtain the number of pollutant emission sources in each scenario. In the next step, the LCA of the scenarios was performed using the Eco‐Indicator 99 index. The results of the study showed that scenario 4 had the most positive effects on the environment, with 40% compost, 25% recycling, 20% sanitary landfill, and 15% waste incineration, based on the index. Therefore, it was chosen as the best option for waste management in the city of Rasht. Integr Environ Assess Manag 2023;00:1–9. © 2023 SETAC

“…Akhirnya terbentuklah air tercemar. Selain pencemaran air hujan yang membawa nutrients seperti fosfat, nitrogen, dan zat tercemar lain bersamaan dengan terkikisnya tanah oleh air hujan (Chapra, 1997;Gong et al, 2020), badan air juga mendapatkan tambahan beban pencemaran dari air limbah domestik (Langdon et al, 2019). Badan air yang dimaksud bisa danau, embung, atau sungai.…”

Low awareness of sanitation of urban citizens creates negative effects on the environment which varied. The triggering factors of the phenomenon are education and conservation technology. A conservation technology, eco-technology e.g. constructed wetlands, is proposed to solve the problem. Laboratory work is conducted to obtain comprehensive analysis about floating constructed wetland. The research paper aims to illustrate the efficiency performance of constructed wetlands, with domestic species, in the lab-scaled area from urban wastewater. The constructed wetland media is prepared horizontally. The analysis of its performance leads to a discussion of urban water quality. Samplings and laboratory tests are conducted to examine pH, phosphorus, nitrogen, suspended solids, conductivity, COD, and BOD. The benefit of Nasturtium officinale as FTW media reduce phosphate, nitrate, and BOD as 100% in 14 days. The discharge simulation during 14 days reduce TDS and TSS as 100%.
