Insights into Computer Recycling


See on Scoop.itWaste Waste Everywhere

A recycling company should apply the rules of the Waste Hierarchy when recycling old computers, whatever the age. For example in this case, reuse is the most favoured recycling technique, followed by recovery of working parts then recycling the materials contained within. 

Salman Zafar‘s insight:

As long as the recycling of older equipment is performed ethically and responsibility, we can reduce the environmental impact.

Informal Recycling Sector in Latin America


See on Scoop.itFostering Sustainable Development

Some cities in Latin America are facing this challenge by integrating the informal sector recyclers who are already active in their cities into the municipal solid waste management systems. In many cities, these “recicladores”, “cartoneros” or “catadores” (a few of the many names used for these workers in the region) are responsible for up to 90% of the recyclable waste recovered from the waste stream.

Salman Zafar‘s insight:

Informal recyclers provide important a range of services to municipalities (such as waste collection and recovery in communities that would not otherwise have access to them), as well as cost savings (for example, the extension of landfill life and reduced transport costs), yet are rarely compensated for these benefits.

Synthetic Biology and Biogas Industry


See on Scoop.itRenewables

Essentially a process operating by living organisms, the biogas industry is a natural target for synthetic biology. Among numerous microbes in anaerobic digester, methanogenic Archaea are one of a few microbial groups that have been extensively studied, and a number of genetic tools are available for engineering via synthetic biology. 

Salman Zafar‘s insight:

Synthetic biology also holds great potentials to revolutionize the biogas industry. To achieve this goal, joint efforts between the biogas industry and academia must be made. The former side needs to understand what synthetic biology can achieve, while the latter side should identify which parts of the process in the biogas industry can be re-designed and optimized by synthetic biology.

Roadblocks in Waste-to-Energy Implementation


See on Scoop.itEnergy Blog

The biggest obstacle to the implementation of Waste-to-Energy (or WTE) lies not in the technology itself but in the acceptance of citizens.

Salman Zafar‘s insight:

Waste-to-Energy or recycling has kept public discourse from questioning whether there may not be intermediate or case specific solutions. This polarization serves to move the conversation nowhere. For now it can be agreed that landfills are devastating in their contribution to Climate Change and must be done away with.

More action necessary towards banning plastic bags


Salman Zafar:

Places such as England, New Delhi and South Australia are also eliminating plastic bags through bans and taxes. When China enacted a ban on plastic bags, it saved 1.6 million tons of petroleum that would have been used for production.

Originally posted on Kalli Ricka Wolf:

Walk down almost any street in Tucson and you’re bound to see plastic grocery bags in the sewer drains, stuck in bushes and cactuses. Our windy environment makes for a storm of plastic bags being picked up and blown around, which makes them an eyesore and a threat to our desert ecosystem. Before the problem gets more out of hand, the city ought to place a tax or ban on plastic bags.

More than one trillion plastic bags are used worldwide annually, according to Reuseit.com, but only 1 percent of them are recycled.

“If you’ve never looked at this issue before, you could be astounded and overwhelmed,” said Leif Abrell, a scientist who works in the Arizona Laboratory for Emerging Contaminants at the UA. “It’s insane how much material is out there, and there are different ways that this is a problem for our environment.”

Hazards of Olive Oil Wastes


See on Scoop.itWaste Waste Everywhere

Due to its complex compounds, olive processing waste  is not easily biodegradable and needs to be detoxified before it can properly be used in agricultural and other industrial processes. 

Salman Zafar‘s insight:

Even a small quantity of olive wastewater in contact with groundwater has the potential to cause significant pollution to drinking water sources. The problem is more serious where chlorine is used to disinfect drinking water.

Biogas Production in Tanneries


See on Scoop.itEnergy Blog

Anaerobic digestion of tannery wastes is an attractive method to recover energy from tannery wastes. This method degrades a substantial part of the organic matter contained in the sludge and tannery solid wastes, generating valuable biogas, contributing to alleviate the environmental problem, giving time to set-up more sustainable treatment and disposal routes. Digested solid waste is biologically stabilized and can be reused in agriculture.

Salman Zafar‘s insight:

When the locally available industrial wastewater treatment plant is not provided by anaerobic digester, a large scale digestion can be planned in regions accommodating a big cluster of tanneries, if there is enough waste to make the facility economically attractive. In this circumstance, an anaerobic co-digestion plant based on sludge and tanneries may be a recommendable option

What does 3D Printing mean for Waste


See on Scoop.itWaste Waste Everywhere

3D printing is something of a double-edged sword when it comes to waste. It creates new recycling problems, but has considerable potential to help prevent waste. It could even be an outlet for recycled plastics. 

Salman Zafar‘s insight:

3D printing offers numerous challenges and opportunities to the waste management industry. The best approach would be for the waste management industry to engage positively with the designers and manufacturers of the 3D printing devices, trying to identify opportunities to ensure that the circular economy doesn’t become an afterthought.

Islam and Nature


See on Scoop.itFostering Sustainable Development

There are over 6,000 verses in the Holy Quran of which more than 500 deal with the natural phenomenon. Allah, the Almighty, repeatedly calls on mankind to reflect on His signs, which include all aspects of nature such as trees, mountains, seas, animals, birds, stars, the Sun and the moon and our own hearts. Islamic jurisprudence contains regulations concerning the conservation and allocation of scarce water resources;

Salman Zafar‘s insight:

Humans have the capacity to subvert the world, far more than any other living species. We also have the capacity to uphold the physical world. Islam believes that all human souls come from a garden, and that at the end of time each soul will either enter the garden or the fire.

Green Lessons from Hadith


See on Scoop.itFostering Sustainable Development

Prophet Muhammad categorically taught people to live on less, to protect animal and plant life, and to worship the Creator by being merciful to the creation. What is also distinctive about Prophet Muhammad’s advice is the connection between ethical practices and the eternal effects in the life after death, which represents a greater incentive for Muslims to care for the earth and its resources.

Salman Zafar‘s insight:

Animals have a huge role in the ecological welfare system. The tenets of the Shariah law towards animal rights make it obligatory for any individual to take care of crippled animals, to rescue strays and to guard a bird’s nest of eggs.

Composting for Beginners


See on Scoop.itRenewables

Composting can be categorized into different categories depending on the nature of decomposition process. The three major segments of composting are anaerobic composting, aerobic composting, and vermicomposting.

Salman Zafar‘s insight:

Aerobic composting is the process by which organic wastes are converted into compost or manure in presence of air. In this process, aerobic microorganisms break down organic matter and produce carbon dioxide, ammonia, water, heat and humus, the relatively stable organic end-product. Although aerobic composting may produce intermediate compounds such as organic acids, aerobic microorganisms decompose them further.

Biomass Exchange and Supply Chain Management


See on Scoop.itRenewables

The supply chain management in any biomass project is a big management conundrum. The complexity deepens owing to the large number of stages which encompass the entire biomass value chain.

Salman Zafar‘s insight:

Biomass Exchange is an attractive solution to different problems afflicting biomass project, at the same time providing the investors and entrepreneurs with a multi-million dollar opportunity. Although such a concept has been in existence in the developed world for a long time now, it has not witnessed many entrepreneurial ventures in developing nations where the need to strengthen the biomass supply chain becomes even more necessary.

Supply Chain in Biomass Projects


See on Scoop.itRenewables

Supply chain management in any biomass based project is nothing less than a big management conundrum. The complexity deepens owing to the large number of stages which encompass the entire biomass value chain. It starts right from the resource harvesting and goes on to include the resource collection, processing, storage and eventually its transportation to the point of ultimate utilization.

Salman Zafar‘s insight:

Although most of the problems discussed above, are issues inherently associated with the usage of biomass resources, they can be curtailed to a larger extent by strengthening the most important loophole in such projects – The Biomass Resource Supply Chain.

Salman Zafar‘s insight:

reatment of aluminum cans is the closest to a true upcycling model. These containers can be melted down and made into brand new cans, and in the process save over 90% of the energy required to make brand new cans from scratch. This cycle can be repeated forever, reducing energy consumption and effectively removing aluminum from the waste stream.

Recycling of EPS Foam


See on Scoop.itWaste Waste Everywhere

EPS foam is a highly popular plastic packaging material which finds wide application in packaging of food items, electronic goods, electrical appliances, furniture etc due to its excellent insulating and protective properties.

Salman Zafar‘s insight:

The cost of transporting bulky polystyrene waste discourages recyclers from recycling it.  Organizations that receive a large amount of EPS foam (especially in packaging) can invest in a compactor that will reduce the volume of the products. Recyclers will pay more for the compacted product so the investment can be recovered relatively easier.
