According to the 2014 Disposal Facility-Based Characterization of Solid Waste in California (PDF download), construction and demolition (C&D) materials are estimated to account for between 21.7 to 25.5 percent of the disposed waste stream. Previous study estimates have ranged from 29 percent in 2008 to 24 percent in 2004.
Based on volume, Construction and Demolition (C&D) waste is the largest waste stream in the EU. That's why the European Commission is introducing a new protocol on construction and demolition.
Preliminary assessment is an essential part of construction and demolition waste management. This guideline provides a methodology for this assessment to support national authorities in achieving the EU 2020 target for CDW recycling.
As of January 1, 2017, State law requires 65% waste diversion for all new constructionand commercial renovations, and most residential additions/alterations. For more information visit the California Building Standards Commission website at:
Requirements for projects receiving a Building Permit dated Nov. 2, 2017 or later: a project must divert from the landfill 65% of waste materials removed from the site, excluding Alternative Daily Cover (ADC). The City continues to enforce State requirements, but in addition, the City will not allow ADC to be counted as diversion, since this is material that is placed on the active face of a landfill at the end of the day. In addition to California Building Code requirements, the City of Emeryville will include demolition-only projects as subject to the City requirements. Read the full ordinance for more information.
Exemptions: Projects generating less than 2 lbs. per square foot of project space, and residential remodeling projects that don't increase the livable space of the building will be exempt from this requirements. All other permitted construction and demolition projects will be subject to the above requirements.
Florida has a MSW (municipal solid waste) recycling goal that includes C&D (construction and demolition) debris. Construction and Demolition Debris (link to 62-701.200(24) accounts for almost 25 percent of Florida's total MSW stream. A wide range of these materials can be recovered and reused or recycled into new products.
25) "Construction and demolition debris" means discarded materials generally considered to be not water soluble and non-hazardous in nature, including but not limited to steel, glass, brick, concrete, asphalt material, pipe, gypsum wallboard, and lumber, from the construction or destruction of a structure as part of a construction or demolition project or from the renovation of a structure, including such debris from construction of structures at a site remote from the construction or demolition project site. The term includes rocks, soils, tree remains, trees, and other vegetative matter which normally results from land clearing or land development operations for a construction project; clean cardboard, paper, plastic, wood, and metal scraps from a construction project; effective January 1, 1997, except as provided in Section 403.707(13)(j), F.S., unpainted, non-treated wood scraps from facilities manufacturing materials used for construction of structures or their components and unpainted, non-treated wood pallets provided the wood scraps and pallets are separated from other solid waste where generated and the generator of such wood scraps or pallets implements reasonable practices of the generating industry to minimize the commingling of wood scraps or pallets with other solid waste; and the minimum amounts of other nonhazardous wastes that are generated at construction or demolition projects, provided such amounts are consistent with best management practices of the construction and demolition industries. Mixing of construction and demolition debris with other types of solid waste will cause it to be classified as other than construction and demolition debris.
The Solid Waste Division operates a state-permitted, active, construction and demolition landfill on Old Salisbury Road for waste materials generated for construction and demolition activities. There is sufficient land at the Old Salisbury Road Landfill to meet construction and demolition waste disposal needs until approximately the year 2030.
The California Integrated Waste Management Act of 1989 (AB 939) requires that local governments ensure that solid wastes are diverted from disposal. In addition, the CalGreen building standards mandate that 65% of construction and demolition materials be reused, recycled, composted or otherwise diverted from landfill disposal. The CalGreen regulations cover both residential and commercial projects, based on the size of the project. For more information requirements, please see the CalGreen C&D Regulations Table.
Construction and demolition waste (CDW) accounts for more than a third of all waste generated in the EU. It contains a wide variety of materials such as concrete, bricks, wood, glass, metals and plastic. It includes all the waste produced by the construction and demolition of buildings and infrastructure, as well as road planning and maintenance.
Some components of CDW have a high resource value, while others may have a lower value, but could still be easily reprocessed into new products or materials. Technology for the separation and the recovery of construction and demolition waste is well established, readily accessible and generally inexpensive.
When it is not separated at source, construction and demolition waste can also contain small amounts of hazardous materials such as solvents and asbestos. These can pose particular risks to the environment and impede recycling.
Despite its potential, the level of recycling and material recovery of construction and demolition waste varies greatly across the EU, ranging from less than 10% to over 90%. EU counties apply different definitions of construction and demolition waste, which makes cross-country comparisons difficult.
The California Green Building Standard Codes (CALGreen) set recycling requirements for construction and demolition (C&D) projects. CALGreen requires the recycling and/or salvaging for reuse a minimum of 65% of the non-hazardous construction and demolition project waste. Applicants must comply with the CALGreen provisions and the City of Laguna Beach Municipal Code Chapter 7.19 (Construction and Demolition Requirements) whichever is more stringent.
OPTION TWO: Self-haul all construction and demolition debris generated at the project site to an approved construction and demolition facility listed in the Green Halo database. Donated items count towards diversion rate. Documentation is required. Click here for more information about how to donate.
Construction and demolition (C&D) waste is typically generated when a building or structure is constructed or demolished. The CalGreen Building Standards Code and the City of Jurupa Valley Municipal Code requires that certain building and demolition projects recycle at least 65% of the waste generated. Typically, these waste streams are sent to a Materials Recovery Facilitie ("MRF") to be sorted and recycled.
Construction and demolition waste generated in the Republic of Korea accounts for about half of the annual waste. The generation of construction waste is expected to increase gradually due to obsolete structures and reconstructions that have reached the end of their service life. Considering the geographical characteristics of Korea, where the land area is small and about 70% of which is mountainous, landfilling of waste is absolutely limited. Therefore, resource circulation such as recycling of construction waste is an urgent and important task. This paper overviews the current status of construction waste generation, treatment, and the flow of government policies in Korea. Furthermore, the current status, limitations, and stakeholder efforts regarding recycling of recycled aggregate from construction waste were reviewed. Data used in this paper were mostly collected from government reports, construction waste regulations, and research papers. The results show that construction waste management systems have been enacted and revised in line with social needs, and each stakeholder is making an effort to use the construction waste practically. The findings can provide valuable examples for countries that lack construction waste management systems.
The land area of the Republic of Korea is 99,720 km2, which is only the 109th in the world, but it is 28th in population with about 51 million people. This is the most densely populated country among OECD members (CIA 2020; OECD 2015). Moreover, in Korea, where mountainous areas occupy about 70% of the land area, most of the population lives densely in urban areas. Therefore, a series of demolition work inevitably occurs continuously. Civil and building constructions are expected to steadily increase, and in exchange, construction and demolition (C&D) waste is also expected to increase due to the dismantling of old infrastructures and reconstructions (Lee et al. 2013).
Improper disposal of waste occurs quite frequently in Korean society. Some construction companies illegally dump waste into nature. Some others rent empty warehouses and fill them with waste and then run away (ME 2019a). These dumped wastes are separated, sorted, and recycled, but in the end, all of these activities result in waste of the national budget. As of 2016, 52% of 474.6 million m3 of the nationwide landfill capacity was already filled with waste (ME 2017). The Sudokwon Landfill Management Corporation announced that the direct import of C&D waste to the landfill sites in the metropolitan area will be prohibited as of 2022. Thus, only the remaining C&D waste that has undergone the recycling process at recycling plants can be brought in. This policy is expected to reduce the amount of C&D waste brought into the landfill sites to 751 thousand tons by 2025, which is about 52% of the amount of C&D waste imported in 2019. Therefore, establishing a resource circulation system through maximizing waste recycling is an urgent and important task for the transition to a sustainable society. 59ce067264
