Environmentally Sustainable Approach To Waste Management Environmental Sciences Essay

In 1975 the Waste Framework Directive set about a set of policies sing Government control over waste aggregation and disposal. Since this clip several new directives have been established to command the disposal of assorted waste stuffs ( see figure 1 ) , as UK policy moves towards a more environmentally sustainable attack to blow direction, and becomes more to a great extent influenced by EU statute law. Landfill remains the prevailing method of disposal in the UK nevertheless one of the cardinal pieces of EU statute law that influences waste direction policy is the Landfill Directive of 1999, which has been one of the key drivers behind national waste scheme in Scotland since its execution in 2001. This directing sets out marks for cut downing the sum of biodegradable municipal waste ( BMW ) being sent to landfill. Using 1995 as a baseline, the UK has an duty to cut down the sum of BMW being sent to landfill by 75 % of 1995 degrees by 2010, 50 % by 2013 and 35 % by 2020 [ www.wasteawarescotland.org.uk ] . To accomplish these marks national waste schemes place greater focal point on accomplishing increased family waste recycling and recovery rates [ Burnley pp 349 ] . In footings of municipal waste, the chief classs affected are – nutrient, green and risky wastes.

Families in Scotland produce around 566,000 metric tons of nutrient waste every twelvemonth composing chiefly of drinks ( 18 % of entire weight ) , fresh veggies ( 16 % of entire weight ) , fresh fruit ( 9 % of entire weight ) , bakery points ( 12 % of entire weight ) , and meat and fish ( 5 % of entire weight ) [ www.wrap.org.uk ] . This station consumer waste is mirrored in the pre consumer production of nutrient, with waste watercourses generated during the production and packaging of nutrient materials including any overrun, packaging wastes, spoiled nutrients, expired nutrients, overcooked, contaminated or dropped points.

Green Waste:

Green waste is waste that can be broken down of course via decomposition ( by bacteriums or other beings ) . It by and large includes garden waste, such as works fixingss, grass film editings, leaves etc. Basically green waste is waste that can be used for compositing.

Household Hazardous Waste:

Optional Methods for Management:

Figure 2: European States with Facilities Processing Municipal Solid Waste [ Taken from Levis et al 2010, pp 2 ]

One of the operational methods of waste direction available for execution in Scotland involves the intervention of green and nutrient wastes biologically via anaerobiotic digestion [ Levis et Al 2010, pp 1486 ] . Anaerobic digestion is a procedure in which micro-organisms interruption down biodegradable stuff in the absence of O to bring forth a biogas ( preponderantly methane and C dioxide ) and a digeste stuff that has the potency for agricultural usage [ DEFRA 2011 ] . To day of the month, AD has non been widely implemented in the UK, with merely a smattering of workss accepting municipally sourced biowaste ( see figure 2 ) [ Breton 2009, pp 38 ] . This may be because AD can merely handle organic waste, and is reliant on unintegrated feedstock with separate beginning aggregations ( i.e. individually collected nutrient and garden waste ) . The manner we collect waste is, nevertheless, altering and new segregated waste aggregations are leting AD installations to use a cleaner feedstock and achieve the optimum C to nitrogen ratio [ Breton 2009, pp 38 ] . Widely used across Europe AD provides an wholly executable option for Scotland ‘s hereafter nutrient waste direction schemes – and is a proved engineering in intervention of this waste. The major factors that limit its execution are the capital cost and the ability to obtain a pure feedstock [ Levis et Al 2010, pp 1494 ] .

Both of these countries give us chances for waste minimization and this is frequently incorporated into many of the methods of waste direction.


However, there has been little published rating of the sensed effectivity and public attitudes towards such strategies, and this is significantly given that recycling strategies are presently to a great extent dependent upon the voluntary behavior of the public [ Williams and Kelly 2002, pp 139 ]

A scheme used in some European Countries and parts of North America has been to microchip the wheelie bins of occupants in order to supervise the sum of non-recyclable waste they generate. The householders are so charged dependant on this sum. Evidence has shown that this kind of differential charging can be successful in cut downing waste [ DEFRA 2011 ] , and the Local Government Association has requested the freedom to follow strategies in the UK.

At present there is small inducement for the homeowner in the UK to deviate waste from disposal, as there is no punishment for non-participation in recycling strategies, and easiness of disposal has generated apathy towards more clip devouring alternate direction options. International instance surveies have shown that direct charging is one attack that can bring forth dramatic consequences in footings of increased recycling and waste minimization. Pay-as-you-throw ( PAYT ) schemes place duty on the homeowner to pull off their waste in a more sustainable mode, with economic sciences being the incentive [ Slack et Al 2009, pp 36 ]

We besides need to see the organizational constructions of waste direction. Peopless recycling behavior does non merely depend on proficient and organizational facets, but besides on its establishments [ Refsgaard et al 3008, pp 760 ] .

There are besides instruments such as the Landfill Tax escalator – financial steps aimed at promoting recreation off from taking nutrient, green and family risky waste straight to landfill by doing it more expensive to make so. 94 % of families in the UK receive a kerbside or doorstep aggregation from their local council for reclaimable stuffs, with a 50 % enlargement since 2010 [ DEFRA 2011 ] .

Families in Scotland produce 566,000 metric tons of nutrient waste every twelvemonth, 62 % of which is collected via council run waste direction enterprises ( either as assorted waste, or nutrient waste merely schemes ) [ www.wrap.org.uk ] .


What seems to be clear is that there is no stand-out individual solution to efficaciously pull off the broad scope of waste watercourses produced in Scotland. What is required is an incorporate direction scheme that is centrally controlled. This allows for a more holistic attack, cut downing the jobs frequently associated with seeking to pull off excessively complex waste direction operations.
