Effective Ways to Minimize Waste on Construction Sites

For some people, the whole thing of “going green” is a trend, but in the world of construction, “going green” is definitely no trend… In fact, it’s a sustainable building practice that’s here to stay. As more cities adopt greener building regulations for new construction, contractors and construction companies alike are going to face the challenge of keeping up with these sustainable building practices.

One of the biggest areas in construction that greener changes need to happen in is construction waste. They say, “waste not, want not,”… well, in the world of construction, “when you waste less, you spend less.” Sustainable building practices, in the form of minimizing waste, means you’re not only building better, energy-efficient buildings but you’re also saving time and money on all your construction projects.

It’s just amazing to look at how the industry has changed over the years. True enough, certain things haven’t changed like state and industry-specific certifications and licenses… If you live in Oregon, you would still need to meet the Oregon continuing education requirements. But as far as sustainable practices, it’s amazing how more and more people are becoming conscious about reducing their carbon footprint to make the environment a better place… Back in the early 1940s to the 1960s, people could have cared less about their environmental impact.

But we are indeed in different times, and the construction industry is doing its part to implement green practices, including reducing construction waste. Here’s how construction companies and contractors are doing their part.

Effective Ways to Minimize Your Construction Waste

1. Avoid Creating Waste in the First Place

To truly manage your construction waste effectively, you should avoid creating it in the first place. Taking steps like taking exact measurements to ensure you have enough materials to build without any unnecessary leftovers is going to help tremendously. Conducting regular inventory checks will prevent you from overordering materials that you already have.

Additionally, properly training your team and educating them on the importance of construction waste management will help them to implement greener practices within their own job responsibilities.

2. Store Your Materials Properly

With construction sites, you’re not always going to be able to haul your materials in and out of a proper storage area; sometimes your materials have to set out on the site. But that also doesn’t mean your materials have to be ruined. You have to first and foremost, secure your site to minimize damage and even theft.

For example, you can store lumber on blocking and make sure to cover it up to prevent any damages. You want to do the same with brick and other masonry. The main thing is that your materials are a huge investment and you need to do all you can to protect your investment.

According to the National Equipment Register, states that have a large economy percentage in agriculture and construction industries are the biggest targets for thieves, and the most common pieces of equipment to steal include valuable pieces that are easy to move, like tractors, mowers, and other tools. Heavier pieces like bulldozers and backhoes aren’t so common because they’re too difficult to move.

3. Add Organization to Your Construction Site

Construction sites seem like they can be a bit chaotic, which they can, but they don’t have to be by simply adding a little organization to your site. Consider separating your recyclable and salvageable materials together in an area to reduce confusion; this just puts everyone on the same page. When your site is organized and your team knows where everything is, it will cause you to spend less money on unnecessary materials, re-doing work, and sorting in the middle of a project.

4. Recycle and Re-Use Your Salvageable Materials

On all of your construction sites, make it a point to recycle materials like paper, plastic, metal, and glass… wood too. In that same token, also make sure that if there’s a way to reduce any costs in construction projects, re-using your salvaged materials is the way to do it. The purpose is to reuse these materials so that they don’t end up in a landfill somewhere… You can’t always avoid waste on all projects but landfills are one of the worst ways to handle your construction site waste.

A Glance at Biggest Dumpsites in Nigeria

Waste dumping is the predominant method for solid waste disposal in developing countries worldwide, and Nigeria is no exception. Nigeria is home to six of the biggest dumpsites in Africa, according to Waste Atlas 2014 report on World’s 50 Biggest Dumpsites published by D-Waste. These dumpsites are located in three most important cities in Nigeria namely, Lagos, Port Harcourt and Ibadan.

Let us have a quick look at the major landfills in Nigeria:

Olusosun

Olusosun is the largest dumpsite not only in Lagos but in Nigeria and receives about 2.1 million tonnes of waste annually comprising mostly of municipal solid waste, construction waste, and electronic waste (e-waste). The dumpsite covers an area of about 43 hectares and it is 18 meters deep.

The dumpsite has been in existence since 1992 and has housed about 24.5 million tonnes of waste since then. A population of about 5 million people lives around 10km radius from the site and numerous health problems like skin irritation, dysentery, water-related diseases, nausea etc. have been reported by residents living around 3km radius from the site.

Solous 2

It is located in Lagos and occupies around 8 hectares of land along Lasu-Iba road. The dumpsite receives about 820,000 tonnes of waste annually and has since its existence in 2006 accepted around 5.8 million tonnes of MSW.

Solous is just 200 meters away from the nearest dwellings and almost 4 million people live within 10km radius from the site. Due to the vulnerable sand formation of the area, leachate produced at the dumpsite flows into groundwater causing its contamination.

Epe

Epe dumpsite also in Lagos occupies about 80 hectares of land. The dumpsite was opened in 2010 and has an annual input of 12,000 tonnes of MSW. Epe is the dumpsite which the Lagos State government is planning to upgrade to an engineered landfill and set to replace Olusosun dumpsite after its closure.

Since its existence, it has received about 47,000 tonnes of waste and it is just 500 meters away from the nearest settlement. The dumpsite is also just 2km away from Osogbo River and 7km away from Lekki Lagoon.

Awotan (Apete)

The dumpsite is located in Ibadan and has been in existence since 1998 receiving 36,000 tonnes of MSW annually. It covers an area of 14 hectares and already has in place almost 525,000 tonnes of waste.

The dumpsite is close to Eleyele Lake (2.5km away) and IITA Forest Reserve (4.5km away). The nearest settlement to the dumpsite is just 200 meters away and groundwater contamination has been reported by nearby residents.

Lapite

Lapite dumpsite is also located in Ibadan occupies an area of 20 hectares receiving around 9,000 tonnes of MSW yearly. Since its existence in 1998, it has housed almost 137,000 tonnes of MSW. It is 9km away from IITA Forest Reserve and surrounded by vegetations on both sides of the road since the dumpsite is directly opposite a major road.

Olusosun is the largest dumpsite in Nigeria

The nearest settlement is about 2km away but due to the heavy metals present in the leachate produced in the waste dump, its leakage poses a great threat to groundwater and biodiversity in the area.

Eneka

It is located in Port Harcourt, the commercial hub of South-South, Nigeria along Igwuruta/Eneka road and 9km from Okpoka River and Otamiri River. It receives around 45,600 tonnes of MSW annually and already has about 12 million tonnes of waste in place.

The site lies in an area of 5 hectares and it is flooded almost all year round as rainfall in the area exceeds 2,500mm per annum. Due to this and the resultant flow of the flood which would have mixed with dumpsite leachate; groundwater, surface water, and soil contamination affect the 1.2 million people living around 10km radius from the site as the nearest building is just 200 meters away.
