“…With the growth of urban green areas in China, the amount of garden waste has also increased as a result of landscape maintenance. In the decade from 2011 to 2019, the amount of garden waste in China surged from 22.453 million tons in 2011 to 33.134 million tons in 2019 [1]. However, the recycling rate of garden waste in China is less than 10%.…”

Garden waste compost (GWC) has been applied as an amendment to improve the desalination efficiency, nutrient availability and diversity of the microbial community in coastal saline soil. Understanding the response of the microbial community to garden waste compost application is of great significance in coastal ecological restoration. Four treatments were established: CK, nonamended control; T1, application of 68 kg·m−3 garden waste compost; T2, application of 15 kg·m−3 bentonite; and T3, a mixture of garden waste compost and bentonite. In addition, soil physicochemical properties, soil enzymes, microbial biomass carbon and the soil microbial community were measured. The results show that T3 had a more significant effect on increasing soil enzymes, as well as microbial biomass carbon and nitrogen, urease, sucrase and dehydrogenase activities. Based on the relative abundance, microbial diversity and linear discriminant effect size (LEfSe) analyses, the amendments can be seen to have increased the microbial abundance and alpha diversity of the bacterial structure and also altered the microbial community structure. RDA and Pearson correlation analysis at the phylum level indicated that available nitrogen, total porosity, hydraulic conductivity, bulk density and EC were the primary determinants of microbial communities associated with this amendment. In conclusion, the application of garden waste compost enables more microorganisms to participate in the soil material cycle, indicating that garden waste composting is beneficial to the restoration of coastal soils.

“…(5) Fallen leaves According to [37], more than 30 million tons of green waste are produced every year in China, with fallen leaves and tree pruning waste representing dominant forms. Another study showed that bulked aerobic composting with fallen leaves has potential for kitchen waste disposal [19], then fallen leaves and KW fertilizer may have combined effects on the vegetation performance of VC.…”

Vegetation concrete (VC) laid as a reinforcement base and covered by a soil layer with vegetation has been increasingly used to beautify the landscape, reduce environmental pollution and control stormwater runoff. In this study, the effects of municipal solid waste (MSW) on vegetation characteristics of modified VC were tested under different mix compositions. We first explored the effects of the mixed concrete environment on Festuca elata and perennial Ryegrass for 60 days. Then, the influence of various MSW contents added to different percentages of cement on scouring resistance of VC was examined. The experimental results revealed that the germination rates and plant heights of both species decreased with the increase in concrete content. Considering the scouring resistances, the optimal mix proportion of MSW-modified VC was recommended as No. 25, with 5% KW fertilizer, 8% cement and 0.5% wheat straw in this study. Furthermore, adding a small amount of fallen leaves or silica fume to VC can promote the growth of both species to some extent, although these additions had an inverse effect on the scouring resistances. The results contribute to beneficial knowledge for future research on the feasibility of the use these species with VC technology for slope ecological restoration.

The increasing number of city park waste / open spaces will contribute to increase the number of city park waste. This study aims to predict waste generation and analyze city park waste's potential as biofuels. The observation was conducted on ten thematic parks in Bandung city. The waste generation model was developed based on the number of trees, season, and park area. The average waste generation is 0.44±0.24 tons/day/park. The seasonal changes' effect in parks had a significant impact with a P-value of 0.02 < 0.05. The most significant variable of the city park's waste generation is the number of trees in every park with a P-value = 0.0002 < 0.05 generation model = 0.5435(number of tree) -0.6783. The characteristics of sulfur and moisture are 0.31% and 2.6% respectively, while carbon content is high as much as 40.45%. The heating value is 15.2 MJ/Kg, and fixed carbon is 72%, while the cellulose is 21.87%. The study concluded that the city parks' waste is potential as raw material for biofuel or transformed into other energy materials.
