how to manage construction waste and yield tangible benefits for the environment and your business

how to manage construction waste and yield tangible benefits for the environment and your business

Waste generated by construction does not just have a massively negative impact on the environment, it also comes with a huge economic price tag. According to aWorld Bank Report, construction waste from building materials accounts for half of the solid waste generated annually. Therefore, it pays for regional and global players in the construction industry to examine their waste disposal methods and make significant changes to create more sustainable ways of working.

While the cost of waste varies from country to country, one thing remains constant - the costs continue to multiply. The construction industry remains one of the biggest culprits to waste contribution. In 2012, 1.3 billion tons of solid waste was created, and this volume is expected to increase to 2.2 billion tons of waste per annum over the next seven years until 2025. Globally, countries are drafting policies to increase recycling of construction waste, and various certifications, such as LEED (Leadership in Energy and Environmental Design) have been put in place to encourage the proper management of construction waste.

This trend is mirrored throughout the GCC region as well. According to a report by Frost & Sullivan, the total waste generated in the GCC was predicted to increase from 94 million tons in 2015 to 120 million tons in 2020. GCC countries are undertaking legislative action to create effective management of waste in construction, and also meet their own sustainability goals. Abu Dhabis Tadweer has developed the Waste Management Master Plan, which proposes to reduce commercial and industrial waste, especially that created by construction and demolition in a bid to position the emirate as a global leader in waste management.

Having said this, there are still many barriers to proper waste management including lack of standardization across the region, low margins, and lack of both, awareness and resources. The approach to sustainability in our region presents an interesting challenge for industry players, particularly due to the harsh weather conditions - however, there is still an incredible opportunity for the sector to positively address these challenges and make a transformational leap in sustainability.

1) The four Rs and a DReduce, reuse, recycle. These three Rs are the primary tenets of recycling and adopting sustainable practices. In construction, these principals become equally important in adding to the sustainability agenda of the company and the country in which industry activities occur. In addition to the three Rs, construction industry players should also add recover - can waste be incinerated to use the energy stored within it? - and dispose - with the most undesirable and last option being the landfill - to fully encapsulate a sustainability agenda.

2) Segregate wasteDue to looming deadlines and budget restrictions, a proper waste management plan is indispensable in this industry. The average construction business generates 100 metric tons of waste each year - and each ton that goes to a landfill incurs additional costs to your business. However, up to 90% of the waste generated by construction can be recycled. With this in mind, segregating your waste is one of the most economically viable ways to address waste management enabling you to recycle larger amounts and send less waste to a landfill in order to deliver financially tangible results.

3) Call in the expertsAny construction project requires the coordination, collection and management of waste. This can be a daunting task for a business, not only looking to meet waste management targets, but also having to deal with a variety of waste including hazardous waste. This requires additional attention to detail; thus, hiring a professional waste management company will enable you to better plan your material usage, ensuring the correct storage options and training your staff to follow the correct guidelines. Such a partnership will also ensure that your company benefits from reduced OPEX and higher recycling rates across a variety of projects.

Implementing waste disposal strategies throughout your business to minimize waste and dispose of it in a more environmentally conscious manner, will empower your construction company to reduce its carbon footprint, reduce overheads and increase profits.

a benefitcost analysis on the economic feasibility of construction waste minimisation: the case of malaysia - sciencedirect

a benefitcost analysis on the economic feasibility of construction waste minimisation: the case of malaysia - sciencedirect

Construction waste is becoming a serious environmental problem in many large cities in the world. In Malaysia, the construction industry generates lots of construction waste which caused significant impacts on the environment and aroused growing public concern in the local community. Thus, the minimisation of construction wastes has become a pressing issue. This paper is based on a case study which involved construction waste generation and composition as well as reuse and recycling in the site. The case study also analysed the economic feasibility of waste minimisation such as reusing and recycling of construction waste materials by performing a benefitcost analysis. This study provides an idea of the amount of waste generation, sources and compositions as well as reuse and recycling of materials on the construction sites taking into account the economic dimension. The study shows that waste minimisation is economically feasible and also plays an important role for the improvement of environmental management. In this view, economic instruments for minimising construction waste can be used to raise revenue for environmental policy, encourage prevention efforts, serve to discourage the least desirable disposal practices, as well as to avoid the negative consequences of environmental unfriendly treatment and disposal practices of construction waste materials.

The Arlington, Virginia-based Associated General Contractors of America (AGC) says April producer price index data demonstrates how a wide variety of materials with double-digit price increases could threaten to undermine economic recovery in the United States.

The index for steel mill products climbed 67 percent, while the index for copper and brass mill shapes rose 49 percent and the index for aluminum mill shapes increased 20.5 percent. Other items with especially steep price increases over the past year, says AGC, lumber and plywood costs rising by 85.7 percent from April 2020 to last month. The index for plastic construction products rose 14.2 percent, with a 12.1 percent rise for gypsum products.

Todays producer price index reportbad though it isactually understates the severity of the problems contractors are experiencing, says Ken Simonson, the associations chief economist. Many items have posted even steeper price increases since the data for this report were collected in mid-April, while lead times for producing goods and delivery times to distributors and worksites have grown ever longer and less certain.

The AGC says some of the supply chain problems have resulted from the pandemic or one-time events like the freeze in Texas in February that damaged plants producing inputs for construction plastics. But they say federal policies, particularly tariffs and quotas on key building materials like lumber, steel, and aluminum have exacerbated the price spikes, supply shortages, and delivery delays. They have urged the administration of Joe Biden to end those import obstacles and explore ways to help uncork supply-chain bottlenecks.

States Stephen E. Sandherr, CEO of the AGC, The Biden administration must address these unprecedented lumber and steel costs and broader supply-chain woes or risk undermining the economic recovery. Without tariff relief and other measures, vital construction projects will fall behind schedule or be canceled.

According to the company, the unit is compatible with excavators with an operating weight ranging from 30 tons (60,000 pounds) to 45 tons (90,000 pounds) and meant for sectors where power and sturdiness are essential, such as in quarries, where you need to treat large quantities of material like coal and phosphate.

The MB-HDS523 can also be used to move, sift, and aerate soil in excavating, earthmoving and large trenching projects. Described by MB Crusher as the only HDS unit with five shafts positioned to ensure a greater production rate and processing speed, the MB-HDS523s contains a V Shaft System that is designed to create a simultaneous dual screening effect and increases production.

The unit features a concealed comb that allows the material to enter and flow through the rotors without jamming. It also comes with a removable front upper casing, giving the unit a greater closing angle and increase production.

In addition to power, the company says the unit is also durable. Suitable for demanding construction sites and heavy workloads, the parts of the MB-HDS523 that are subject to wear are protected by reinforced Hardox steel slab, and the bracket and frame are also thicker, making it a well-performing machine.

To facilitate work on the job site in every aspect, especially when it comes to maintenance, the company says the shaft screener comes with a centralized greasing system to simplify and speed up maintenance operations. Much like other units in the range, the shafts are easily switched out and can be replaced on-site and in a few minutes.

A January survey by the Steel Erectors Association of America (SEAA), a trade association representing the interests of steel erectors, fabricators, contractors, and related service providers, has found that hiring remains the biggest challenge for steel erectors.

The survey, which was sent to members of the SEAA, reported more than 40 percent of respondents said that hiring issues are currently their biggest challenge and 37 percent of them believe that hiring will continue to be a problem over the next three years.

Closely related to this issue is business growth, which the association says has been hindered by the inability to hire enough people with the right skills. More than 18 percent of member respondents currently face business growth challenges with that number expected to increase over the next three years.

SEAA has successfully been growing its Ironworker Craft Training program over the last eight years. We currently have nearly 30 members participating in the program with more joining all the time, said Geoff Kress, president of SEAA. In addition, we have launched an aggressive video production schedule to create about 20 short training videos by the end of the year. These videos align with the SEAA/NCCER ironworker training curriculum.

economic benefits of construction waste recycling enterprises under tax incentive policies | springerlink

To further explore the development of construction waste recycling enterprises and promote the recycling of construction waste resources in China, a system dynamics model of the economic benefits of construction waste recycling enterprises is established using the system dynamics method and taking the tax incentive of the Guangzhou Municipal Government as an example. The economic benefits of construction waste recycling enterprises are analyzed from the perspective of the total cost, total revenue, and total recycling amount. The results of the MATLAB simulation and numerical analysis show that (1) by simulating the effects of different taxes such as value-added tax (VAT), education surcharge, urban construction tax, and enterprise income tax on the economic benefits of construction waste recycling enterprises, it is found that when tax incentives reach 70%, the VAT favorable policies bring the highest gains, followed by enterprise income tax, whereas favorable education surcharge policies and urban construction tax have the least impact on economic benefits. (2) Taking the monetary subsidy of the Guangzhou municipal government as an example, it is estimated that the total revenue of construction waste recycling enterprises will increase by 33.56% annually in 2030. When the new production technology is adopted, the return on investment (ROI) will reach 46.8% in 2030 compared to previous technological improvements. In the simulation scenario, the ROI will be 42.2%, which has a good incentive effect on the cost control of enterprises. (3) Increasing the available power to VAT and corporate income tax can improve the profitability of construction waste recycling enterprises in China; however, tax incentive policy will no longer be the main factor affecting the benefits of enterprises when a certain time is reached. (4) It is suggested that the government improves the relevant tax laws incentive policies, increase tax incentives, and add equipment tax incentive policies, actively change the tax mode, and increase indirect tax models to improve the economic benefits of enterprises. The research results provide a decision-making reference for the government to formulate laws and policies related to the economic benefits of construction waste recycling and promote the development of the construction waste recycling industry, the development of new industries, such as waste recycling and treatment, and the formation of industrial chains, to achieve the strategic goal of sustainable development.

Economic instrument is indubitably perceived as effective for encouraging or forcing contractors to conduct environmentally friendly construction practices. Previous studies in relation to this topic mainly put emphasis on economic analysis of construction and demolition (C&D) waste management from a static point of view, which failed to consider its dynamics nature by integrating all essential activities throughout the waste chain. This paper is thus intended to highlight the dynamics and interrelationships of C&D waste management practices and analyze the costbenefit of this process using a system dynamics approach. Data related to concrete and aggregate of a construction project in Shenzhen was collected for the application of the proposed model. The findings reveal that net benefits from conducting C&D waste management will occur, but a higher landfill charge will lead to a higher net benefit, as well as an earlier realization of the net benefit. In addition, the general public under a higher landfill charge will suffer from a higher environmental cost caused by illegal dumping. The simulation results also suggest that current regulation in Shenzhen should be promoted to facilitate a dramatic increase in net benefit from the implementation of C&D waste management. This research is of value in facilitating better understanding on the dynamics of C&D waste management activities throughout the waste chain, as well as providing a tool for simulating the costbenefit of C&D waste management practices over the project duration.
