21 Comments

Biogas plants are decentralized energy system that can lead to self-sufficiency in heat and power requirements, and at the same time reduces environmental pollution. A biogas plant stabilizes organic waste through natural biological process in the absence of air and transforms waste into biogas and biofertilizer. Biogas facilities are well-suited to wet organic material and are commonly used for treating biodegradable waste materials such as waste paper, grass clippings, leftover food, sewage and animal waste. The components of a modern biogas plant includes manure collection, anaerobic digester, effluent treatment plant, gas storage, and CHP or electricity generating equipment. Working of … Continue reading →

Infectious wastes may include all waste items that are contaminated with or suspected of being contaminated with body fluids such as blood and blood products, used catheters … Continue reading →

Thermal Technologies for MSW-to-Energy Conversion

By | | , ,
Leave a comment

Thermal (or thermochemical) MSW-to-energy conversion systems consist of primary technologies which convert the municipal waste into heat or gaseous and liquid products, together with secondary conversion technologies which transform these products into more useful forms of energy, such as heat and electricity. A wide array of thermal waste-to-energy technologies are available to convert the energy stored in solid wastes into more useful forms of energy. These technologies can be classified according to the principal energy carrier produced in the conversion process. Energy carriers are in the form of heat, gas, liquid and/or solid products, depending on the extent to which … Continue reading →

The Concept of Generalised Extended Producer Responsibility

By | | , ,
3 Comments

The notion of Extended Producer Responsibility (EPR) has been part of the waste policy for a long time, particularly within the OECD countries. According to the OECD, EPR “aims to make producers responsible for the environmental impacts of their products throughout the product chain, from design to the post-consumer phase” [1]. EPR alleviates the burden of Public Administrations for managing end-of-life products, while -if properly designed- incentivising waste prevention and recycling. Current Limitations of EPR After years of implementation it can be argued that Extended Producer Responsibility has not in fact been so extended. Several limitations are common: a) producer … Continue reading →

Scrap metal is a valuable commodity in high demand by small and large corporations. This is why many people have become interested in recycling scrap metal. It can be good for the environment because when the metals are recycled, they’re less likely to end up in landfills, thereby reducing environmental pollution. Moreover, recycling scrap metal can help conserve energy used in manufacturing. Instead of making new metals from scratch, people and businesses can use recycled ones, reducing energy consumption and reliance on new resources. Yet aside from the ones mentioned, scrap metal collection can be a great way to earn … Continue reading →

A Beginner’s Guide to Composting

By | | , ,
7 Comments

Composting occurs when biodegradable waste is piled together in a pit or a compost bin. The temperature of the organic waste increases due to the microbial activity of the piled material. The composting temperature often reaches 65 degrees to 75 degrees Celsius within a few days and then declines slowly. This high temperature hastens the elimination of pathogens in the waste stream and facilitates the composting process. The Composting Process The composting process is a complex interaction between the waste and the microorganisms within the waste. The microorganisms that carry out this process fall into three groups: bacteria, fungi, and … Continue reading →
