Bad odors and prevention of formation of Hydrosulfuric Acid (H2S)
Odor pollution is a subject of increasing concern as a cause of discomfort to the population, especially in activities where its most direct environmental impact (solid waste treatment, water purification, etc.) has been progressively reduced. Less attention has traditionally been devoted to gaseous emissions than to liquid and solid emissions, mainly because of the greater risk to human health ...

Refined Shredding of Waste Plastics to Help Recycle “White Pollution” into Resources!
The 2021 report of the UN Environment Program shows that between 1950 and 2017, the world produced a total of about 9.2 billion tons of plastic, and about 7 billion tons became plastic waste. The plastic recycling rate is less than 10%, and more than 70% of plastics are directly discarded in the soil, air, and ocean, causing serious "white pollution". Therefore, how to reduce plastic pollution ...

General Solid Waste Shredder—Shearing-Type Shredder
For solid waste pretreatment, solid waste shredder is required to have the advantages of high throughput, low power consumption, wide material adaptability, and low noise. These requirements limit the application of hammer crushers, impact crushers, jaw crushers, antiroll crushers, and cone crushers for solid waste treatment, especially for municipal solid waste. The shearing type shredder can ...

Determination of greenhouse gas emission reductions from sewage sludge anaerobic digestion in China
Sewage sludge is a considerable source of greenhouse gas (GHG) emission in the field of organic solid waste treatment and disposal. In this case study, total GHG emissions from sludge anaerobic digestion, including direct and indirect emissions as well as replaceable emission reduction due to biogas being reused instead of natural gas, were quantified respectively. The results indicated that ...

Polyhydroxyalkanoate (PHA) production from sludge and municipal wastewater treatment
Polyhydroxyalkanoates (PHAs) are biodegradable polyesters with comparable properties to some petroleum-based polyolefins. PHA production can be achieved in open, mixed microbial cultures and thereby coupled to wastewater and solid residual treatment. In this context, waste organic matter is utilised as a carbon source in activated sludge biological treatment for biopolymer synthesis. Within the ...

Effect of co-managing organic waste using municipal wastewater and solid waste treatment systems in megacities
A model was developed to calculate the mass and heat balances of wastewater and municipal solid waste treatment plants when these plants operate either separately or together with a mutual dependence on mass and energy. Then the energy consumption, life cycle costs (LCCs), greenhouse gas (GHG) emissions and effluent quality were evaluated under various scenarios to identify the most effective ...

Ragger Wire Shredding Plant
Ragger wire consists of the plastic staples, tape, labels and baling wire found in baled post-consumer paper waste, we also call them as “pulper tail”. It is made up of approximately 45% steel and 55% post consumer waste and must be removed from the pulper. During the pulping process, the waste material winds around the wire, creating a tail-like chain which is highly compressed and ...
