Recyclable Waste Collection Methods

English: glass and plastic (bottles) recycling...

There are three basic ways in which communities can offer plastic recycling collection services for plastic bottles and containers. The first, and most widely accessible, collection method is curbside collection of recyclables. Curbside recycling programs are generally the most convenient for community residents to participate in and yield high recovery rates as a result. Communities that provide curbside collection generally request residents to separate designated recyclables from their household garbage and to place them into special receptacles or bags, which are then set out at the curb for collection by municipal or municipally-contracted crews.

The second collection method is known as drop-off recycling. In this method, containers for designated recyclable materials are placed at central collection locations throughout the community, such as parking lots, mosques, schools, malls or other civic associations. The containers are generally marked as to which recyclable material should be placed in them. Residents are requested to deliver their recyclables to the drop-off location, where recyclables are separated by material type into their respective collection containers.

The last collection method employs the use of buy-back centers. Most buy-back recycling centers are operated by private companies and pay consumers for recyclable materials that are brought to them. Buy-back centers usually have purchasing specifications that require consumers to source separate recyclable materials brought for sale. These purchase specifications can greatly reduce contamination levels and allow the buy-back center to immediately begin processing the recyclables they purchase, while providing consumers with an economic incentive to comply with the specifications.

Biomass Energy in Jordan

Image via Wikipedia Municipal solid wastes represent the best source of biomass in Jordan. In terms of quantity per capita and constituents, the waste generated in Jordan is comparable to most semi-industrialized nations. The per capita of waste generated in Jordan is about 0.9 kg/day. The total generation of municipal waste in Jordan is estimated at 1.84 million tons per year.   The main resources of organic waste in Jordan that can be potentially used to produce biogas are summarized as follows: Municipal waste from big cities Organic wastes from slaughterhouse, vegetable market, hotels and restaurants. Organic waste from agro-industries Animal manure, mainly from cows and chickens. Sewage sludge and septic. Olive mills. Organic industrial waste According to a study conducted by the Greater Amman Municipality, around 1.5 million tonnes of organic waste was generated in Jordan in 2009. In addition, an annual amount of 1.83 million cubic meter of septic and se...

Vermicomposting

Image via Wikipedia Vermicomposting is a type of composting in which certain species of earthworms are used to enhance the process of organic waste conversion and produce a better end-product. Vermicomposting is a mesophilic process utilizing microorganisms and earthworms. Earthworms feeds the organic waste materials and passes it through their digestive system and gives out in a granular form (cocoons) which is known as vermicompost. Like regular compost, vermicompost also benefits the environment by reducing the need for chemical fertilizers and decreasing the amount of waste going to landfills/dumpsites. Vermicompost is primarily earthworm excrement, called castings, which can improve biological, chemical, and physical properties of the soil. The chemical secretions in the earthworm’s digestive tract help break down soil and organic matter, so the castings contain more nutrients that are immediately available to plants. Earthworms consume various organic wastes and reduce...

BioOil - The Future Oil

Bio-oil is a dark brown liquid and has a similar composition to biomass. It has a much higher density than woody materials which reduces storage and transport costs. Bio-oil is not suitable for direct use in standard internal combustion engines. Alternatively, the oil can be upgraded to either a special engine fuel or through gasification processes to a syngas and then bio-diesel. Bio-oil is particularly attractive for co-firing because it can be more readily handled and burned than solid fuel and is cheaper to transport and store.   Co-firing of bio-oil has been demonstrated in 350 MW gas fired power station in Holland, when 1% of the boiler output was successfully replaced. It is in such applications that bio-oil can offer major advantages over solid biomass and gasification due to the ease of handling, storage and combustion in an existing power station when special start-up procedures are not necessary. In addition, bio-oil is also a vital source for a wide range of organic co...
