Nigeria, like many different Sub-Saharan Africa international locations, has a waste administration downside. The Nigerian Nationwide Municipal Waste Administration Coverage (2020) offers no estimate however states that “Nigeria produces a big quantity of strong waste out of which lower than 20% is collected by means of a proper system”.
That is decrease than the World Financial institution’s estimate of common waste assortment for Sub-Saharan international locations, which is 44 p.c. It additionally contrasts with the European and North American assortment price – 90 p.c of waste generated.
The issue is just not solely how a lot waste is collected however the lack of correct knowledge about how a lot waste is being generated within the first place. The Lagos State is an effective instance. Nigeria’s most populous metropolis generated 10,000 tonnes of waste per day in 2005. And the Lagos State stated in 2018 that the quantity of waste generated then far “outweighs the official determine of 13,000 tons per day”.
Managing this waste, from assortment and transportation to disposal, is a significant problem for Lagos, which accounts for a big proportion of Nigeria’s waste. The inhabitants of Lagos state, urbanisation, consumption patterns and the dimensions of financial exercise work collectively to extend waste technology.
The Nigerian Nationwide Municipal Waste Administration Coverage (2020) has the potential to remodel waste administration across the nation.
The coverage proposes a system to separate, recycle and deal with waste, preserve pure assets and create alternatives to earn a dwelling from waste.
However the coverage hasn’t been absolutely carried out.
In a latest article, my colleagues and I wrote in regards to the want for Lagos State to place in place a powerful coverage framework that includes waste hierarchy pointers. The waste hierarchy is the concept the issues we do to waste aren’t equally fascinating. First must be prevention; then reuse, recycling, restoration and (least fascinating) disposal.

We discovered that in Lagos, this hierarchy wasn’t being adopted. Residents generate combined waste with out separation or sorting. Households retailer their waste primarily in plastic luggage, sacks and buckets. Contracted waste collectors accumulate combined waste and transport it on to dumpsites. Waste pickers at dumpsites get well beneficial supplies and waste is burnt at these websites.
In apply, the waste hierarchy has been turned the other way up in Lagos State. Waste is just not being collected, transported, recovered and disposed of in a sustainable approach – one that doesn’t endanger the setting, human well being and future generations.
How Lagos collects waste
The Lagos State Waste Administration Authority was arrange in 1991 to gather, transport and eliminate municipal and industrial waste.
In latest occasions, the authority has deployed road sweepers and improved open dumpsites. It launched 102 waste assortment vans and the Undertake-A-Bin programme, underneath which households and companies should buy their waste bins. It began the Lagos Recycle initiative utilizing a sensible waste assortment and reporting software program utility, and has invested in tools to handle dumpsites.
It launched the Blue Field Initiative, which goals to advertise the tradition of sorting waste on the level of technology. Nonetheless, this initiative has crumbled.
Ongoing initiatives to lift social consciousness about environmental points embrace summer season college for college students and sanitation advocacy.
Nonetheless, Lagos continues to supply a big amount of waste with out sufficient mechanisms for managing it.
Weaknesses in waste administration
Nearly all of Lagos residents will not be conscious of the environmental significance of waste separation and sorting. This must be step one in a sustainable administration system.
The costs of the person waste bins offered by the Lagos waste authority, which is meant to advertise waste separation and sorting, are too excessive. For that reason, some residents (particularly from low-income households) use plastic luggage, sacks and buckets as an alternative of bins.
Additionally contributing to poor waste administration in Lagos State are:
-
irregular and sporadic assortment
-
residents’ unwillingness to pay
-
the collapse of the supplies restoration and recycling facility (Olusosun buy-back facility)
-
open burning at dumpsites, which endangers lives
-
harmful situations for road sweepers on roads and highways
-
insufficient funding
-
poor know-how
-
weak coverage framework
-
insufficient social improvement
-
inconsistencies in enforcement and monitoring.
Bettering waste administration in Lagos
The Lagos State Waste Administration Authority must establish probably the most applicable waste streams (a number of, single or soiled recycling) in accordance with the earnings degree of residents. The a number of recycling stream signifies that a number of bins are offered for the gathering of various recyclable supplies. A single recycling stream includes amassing all recyclable supplies in a single bin. Soiled recycling streams put all waste in a single bin with out sorting and separation.
The a number of stream is most suited to high-income areas and the soiled stream extra sensible for low-income areas.
The soiled recycling system is just like the practices of cart pushers who accumulate unsorted waste from households in wheelbarrows. The distinction is that residents can eliminate their waste in a bin of their selection for a set price (pay-as-you-throw) in waste assortment automobiles assigned to their space.
The Lagos State Waste Administration Authority, coverage makers, waste collectors, neighborhood representatives, residents and different related stakeholders decides
which waste belongs within the 3-in-1 and 2-in-1 bins and units the bin costs for the pay-as-you-throw system after correct session.
Avenue sweepers and waste pickers ought to turn into metropolis workers. Sweepers must be changed by sweeping vans with applicable coaching.
Dumpsites must be upgraded to landfills. Applicable applied sciences and digital options must be adopted. And other people must be made conscious of waste separation and sorting by means of the varsity curriculum, social media, tv, radio and billboards.
Equally essential are prudent monetary administration, bin incentives and authorities monetary support for personal people who wish to get into waste administration. The system additionally wants constant enforcement and monitoring.
Above all, this can be a template that may be replicated in different elements of the Nigerian state.
