“…Green waste compost is a new concept for resource utilization developed in recent years [3], which is applied to floricultural substrate or substrate for nursery-grown plant production in most areas [4][5][6]. Recently, green waste compost has become an important means of relieving urban green waste and amending urban polluted soil [7][8][9].…”

Resource utilization of urban green waste compost for soil improvement in afforested land is an important way of digesting urban green waste. In this study, artificial Sophora japonica Linn. Woodland in the Beijing plain, where the million mu (66,700 ha) afforestation project was carried out, was taken as an experimental area to investigate the influences of urban green waste composting on soil improvement and soil microorganisms. Application amounts of green waste composts for each tree were as follows: CK treatment: no application of fertilizer; T1 treatment: 5 kg/each tree; T2 treatment: 10 kg/each tree; T3 treatment: 15 kg/each tree. Results showed that the application of green waste had a significant effect on soil improvement, such as improving of organic matter, available phosphorus, and available potassium content (p < 0.05). The high-level application amount (T3 treatment) had a greater effect on soil improvement. Compared with the control treatment (CK), soil pH in T3 treatment decreased to 7.28-7.45, Soil organic matter contents reached more than 35 g•kg −1 , and soil total nitrogen, soil available phosphorus, and soil available potassium increased by 25-28%, 200-400%, and 80-177%, respectively. Soil carbon-nitrogen ratio has increasing to 15.61-24.38 in the three treatments, which would not obviously slow down the decomposition of organic matter by microorganisms in the soil. After the application of green waste compost, the soil microbial structure was changed. From the operational taxonomic unit (OTU) level, bacterial abundance increased by 12-13%, but the change in bacterial diversity was not significant. The influences of pH and contents of organic matter content, available phosphorus, and rapidly available potassium on the bacterial community were greater. This study will provide the necessary scientific basis for the application of green waste compost in the improvement of soil on afforested land in the Beijing plain.

“…To avoid pathogens and weeds, the temperature should be remain in thermophilic condition which is range 50 -60°C [6] the compost must experience the temperature exceeding 55°C for at least three (3) days so that pathogens and weeds can be eliminated [7].…”

Abstract. Currently, the Ministry of Housing and Local Government manage solid waste in Malaysia, with the participation of the private sector. Food waste represents almost 60% of the total municipal solid waste disposed in the landfill. Material valorisation of food waste usually conducted by biological processes such as composting. Compost, an organic amendment, is the final product of the composting process. These processes are efficient, low cost and environmentally friendly alternative for managing food waste and are used extensively worldwide. Therefore, organic solid waste management practices program for the communities in Perlis was conducted. The main objective of this program was to instilling environment awareness especially among Perlis citizens. This study was investigated the impact of food waste or kitchen waste composting to the citizens in Perlis State and the beneficial of compost fertilizer to our environment especially in plant growth. Composting method was taught to the food premises owner, individuals, teachers, and students and their responses to the composting practices were then summarized. In future, we can prolong our landfill lifespan by practicing organic waste composting and can preserving our environment.

“…Hence, reducing the time required for green waste composting and improving the quality of the compost have become important goals in the use of composting for GW valorization. To this end, several authors have opted for various solutions like the addition of readily decomposable materials, such as animal manure and grease trap waste in order to initiate an intense microbial activity [5,6], biosolids to improve on the microbial activity and GW biodegradation [7] or suitable lignolytic and cellulolytic microorganisms inoculation as a technique to accelerate the composting process and improve on the quality of the end product of the process known as compost [8]. Indeed, many reports have tackled the beneficial impact of fungal inoculation during GW composting and focused acceleration of compost maturity and to improve on its quality.…”

Lignin complexity molecule makes its biodegradation difficult during lignocellulosic wastes composting. So, the improvement of its biodegradation has usually been considered as an objective. This study aimed to determine the impact of Trametes trogii inoculation on organic matter and particularly on lignin and cellulose during green wastes co-composting with olive mill waste water sludge and coffee grounds. Three types of heaps (H1, H2 and H3) were investigated during 180 d. H3 and H2 were inoculated at the beginning of the process (t0) and 120 d later (t120), respectively while H1 was the control. Results showed the absence of pH stabilization in H3 during the first month. Also, in this period we observed a faster degradation of some easily available organic matter in H3 than in the other heaps. After 120 d, a better cellulose decomposition (25.28%) was noticed in H3 than in H1 and H2 (16%). Inoculation during the second fermentation phase induced supplementary lignin degradation in H2 with a percentage of 35% against 23 and 26% for H1 and H3, respectively. For all the runs, a Fourier Transform Infrared analysis showed aliphatic groups' decrease, OH groups' increase and lignin structural modification.
