25 Citations | Moreover, supplementation with exogenous sources of organic carbon appears to be a viable method for enhancing rates of CAH degradation in carbon-limited landfills. |
24 Citations | The results also indicated that leachate recirculation does not affect the degradation rate in aerobic landfills as much as it does in anaerobic landfills |
| Leachate recirculation has a profound advantage on biodegradation of the organic fraction of municipal solid waste in landfills. | |
01 Jul 2006 17 Citations | Other organic materials can also be added to minimize the organic waste that normally goes into landfills. |
29 Citations | Although the landfill soils had higher microbial biomass and activities than the background soil, due to higher organic matter content, the ratios of microbial parameters/organic carbon indicated that inhibition of microbial growth and activities had occurred due to metal stress. |
205 Citations | The amount of attached biomass decreased as filter depth increased, suggesting that most removal of natural organic matter occured at the top of the biofilters. |
28 Citations | Dry matter loss and gas emissions was found to be positively correlated, reaffirming that gas emission is an important factor leading to dry matter loss of stored biomass residues. |

How to reduce waste disposal?4 answersTo reduce waste disposal, various methods can be employed. One approach is the use of a reducing mechanism for handling domestic waste, which includes a rotating box connected to a motor and equipped with hollow blades and ventholes. Another method involves the reduction and recycling of waste materials with adherent asbestos, achieved through negative-pressure cleaning rooms and the removal of asbestos from waste materials. Additionally, a waste volume reduction method can be implemented by forming compaction holes in a waste disposal field and refilling them with waste, thereby reducing waste volume. It is also important to create awareness among people about waste types and the ill-effects of improper disposal, as well as to focus on waste reduction and recycling to minimize waste generation. Finally, a reducing mechanism for solid waste can be used, which includes a smashing case with a feed inlet, screen cloth, guide plates, and crushing rollers. These methods aim to improve waste management and reduce the environmental impact of waste disposal.
What is the importance of reduction in waste management?4 answersReduction in waste management is of utmost importance due to several reasons. Firstly, waste generation is a human activity and not a natural one, causing damage to the environment, water, soil, and air. Secondly, waste, especially food waste, has a significant impact on global warming and can be reduced through waste minimization practices such as improved machinery performance, better quality of fresh produce, and appropriate product disposal. Thirdly, in the construction industry, waste reduction is crucial for sustainable development and requires suitable source plans and incentive policies. Fourthly, hazardous waste management is necessary to protect human beings and the aquatic environment, and techniques such as source reduction, recycling, and treatment can help eliminate hazardous waste. Lastly, waste reduction and management are essential in hotel industries to cut waste disposal costs, protect the environment, and increase guest loyalty. Overall, reduction in waste management is vital for environmental preservation, resource conservation, and sustainable development.
What are the different types of biomass size reduction?3 answersDifferent types of biomass size reduction methods include mechanical-physical, combined-mechanical, thermal-mechanical, irradiation-mechanical, rotary veneer followed by cross-grain shearing, and disintegration using a retting mill. These methods are used to break down biomass into smaller particles, increasing the surface area available for further processing. The goal of size reduction is to achieve a certain grinding level, which can vary depending on the type of biomass and the desired end product. The energy consumption for size reduction can be high, ranging from tens to thousands of kilowatt-hours per ton of dry biomass. However, innovative methods such as rotary veneer and cross-grain shearing have been shown to significantly reduce energy consumption while producing uniform particle shape and size.
Does converting rice husk into biochar help reduce their impact on the environment?5 answersConverting rice husk into biochar can help reduce its impact on the environment. Rice husk biochar (RHB) has been found to be highly effective in the remediation of water and soil environments, adsorbing heavy metals and organic matter, reducing pollutant availability, and enhancing crop growth. The application of rice husk biochar to soil has been shown to increase carbon stability, stimulate the release of humic-like substances, and enhance the abundance and diversity of microbial communities. Biochar derived from rice husk has the potential to improve soil fertility, nutrient retention, and the effectiveness of fertilizer in rice production. Additionally, the high-value utilization of rice husk through biochar production can contribute to carbon emission reduction and the achievement of carbon neutrality goals. Overall, converting rice husk into biochar offers a sustainable approach to managing rice residue and improving soil quality in agricultural systems.
How can waste biomass be used to remove waste from water?5 answersWaste biomass can be used to remove waste from water through various methods. One method involves using agricultural waste biomass as an adsorbent for the treatment of wastewater. Different agricultural waste materials such as rice husk straw, crop waste, fruit peels, nut shells, and dry leaves can be used as low-cost adsorbents to reduce toxins, antinutritional factors, and microbial load from water. Another method involves using alkaline electrolyzed water and supercritical carbon dioxide to pretreat the biomass, effectively damaging its structure and providing convenient conditions for subsequent hydrolysis reactions. Biomass charcoal, prepared from cow dung waste biomass, can be added to water polluted by heavy metals and organic pollutants, and can remove these pollutants through adsorption, deposition, and distribution processes. Additionally, a process involving the use of a light reactor, a dark reactor, and a biomass filter can be used to treat contaminated water by reacting light with nutrients and biomass, and subsequently reacting the biomass with carbon dioxide.
