Summary
This study investigated the Lower Heating Value (LHV) dynamics during bio-mechanical treatment (BMT) of Municipal Solid Waste (MSW). Research focused on bio-drying processes, crucial for integrated waste management and energy recovery in Europe.
Area of Science:
- Environmental Science
- Waste Management Engineering
- Biotechnology
Background:
- European Union directives emphasize material valorization and energy recovery from Municipal Solid Waste (MSW).
- Bio-mechanical treatment (BMT) is an emerging European strategy for MSW management, serving as pre-treatment for landfilling or combustion.
- Research on the bio-drying process, a component of BMT, requires further development.
Purpose of the Study:
- To assess the Lower Heating Value (LHV) dynamics during the bio-drying of MSW.
- To provide insights into the evolution of key process parameters during bio-drying.
- To contribute to the understanding of bio-drying as a pre-treatment method in integrated waste management.
Main Methods:
- Utilized a pilot-scale bio-dryer to conduct experiments on MSW bio-drying.
- Recorded critical process data including airflow, temperature (inlet, outlet, internal), and weight loss.
- Performed initial characterization of the MSW to establish baseline parameters.
Main Results:
- Detailed the dynamics of humidity and volatile solids content during bio-drying.
- Tracked the changes in ammonia concentration throughout the process.
- Monitored the evolution of Lower Heating Value (LHV) in relation to other parameters.
Conclusions:
- The study provides valuable data on the dynamics of LHV and other parameters during MSW bio-drying.
- Findings contribute to the optimization of bio-drying as a pre-treatment in integrated waste management strategies.
- Highlights the need for continued research into bio-drying processes for enhanced material and energy recovery.

01:29Strength and Heat of Hydration
The hydration of cement is an exothermic reaction in which heat is generated as cement hydrates. This heat of hydration is critical to cement's strength development. The rate at which this heat is generated affects the temperature rise, with a majority of the heat being released early in the hydration process, half within the first three days, and about 75% within the first week.
The heat of hydration for each cement compound is significant; for instance, tricalcium aluminate (C3A) and...

02:46Quantifying Heat
Thermal Energy Microscopically, thermal energy is the kinetic energy associated with the random motion of atoms and molecules. Temperature is a quantitative measure of “hot” or “cold”, which depends on the amount of thermal energy. When the atoms and molecules in an object are moving or vibrating quickly, they have a higher average kinetic energy (KE) (or higher thermal energy), and the object is perceived as “hot”, or it is described as being at a higher temperature. When the atoms and...
01:30Microbial Wastewater Treatment
Microbial communities in aquatic ecosystems play a key role in the natural breakdown of contaminants introduced through domestic and industrial effluents. Acting as biological catalysts, these microbes change and mineralize a wide range of organic and inorganic pollutants under different redox conditions.In oxygen-rich surface waters, aerobic heterotrophs lead organic matter breakdown, using oxygen as the terminal electron acceptor to efficiently oxidize substrates to carbon dioxide and water.
02:44Heating and Cooling Curves
When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...

01:10Moisture Content and Bulking of Aggregate
The moisture content of aggregates is a crucial factor in construction, particularly in concrete mixing, as it influences the total water required in the mix. Moisture content represents the water coated on the exterior surface of the aggregate existing in a saturated and surface-dry condition. The total water content of a moist aggregate is the sum of its moisture content and water absorption.
When aggregates are exposed to rain or sit in stockpiles, they absorb moisture, which must be...

01:21Drying Shrinkage
When hardened concrete is exposed to air with a relative humidity of less than 100 percent, it begins to lose the free water within its capillaries. As this water evaporates, the water initially adsorbed onto the calcium silicate hydrates migrates towards these now empty spaces and eventually evaporates as well. Over time, as more water leaves, the volume of the concrete decreases, a phenomenon known as drying shrinkage.
A portion of this drying shrinkage can be reversed; if the concrete is...
