5 MINISTÉRIO DAS CIDADES Secretaria Nacional de Habitação SNH PBQP-H Programa Brasileiro da Qualidade e Produtividade do Habitat PBQP-H Referencial Normativo Nível B do SiAC 7.1. Construction Planning Works Quality Plan (PQO) Construction Company must, for each of their works, elaborate a Works Quality Plan, according to others Quality Management Systems requirements, which must have some elements as follows, when appropriate: i) definition on where the solid and liquid wastes will be destinated (construction solid waste, sewage, used water), which respects the environment. This is ISO 9001:2008 specific for the civil construction industry

6 Legislation Public Policies CONAMA* Resolution no 307- Civil Construction Solid Waste Management- 05/07/2002 (Complemented by CONAMA* Resolution no 348, which includes asbestos products as D class - dangerous) *Brazilian National Environment Council Fonte: Manual de Resíduos Sólidos- Sinduscon - SP

7 CDW classification proposed by CONAMA 307/ CONAMA 348/2004 Resolutions Class A: residues reusable or recyclable as aggregates, Class B: recyclable residues for other applications, such as: plastics, paper/paper board, metals, glasses and others; Class C: residues for which no technologies or economically feasible applications have been developed which allow their recycling/recovery (i.e.: gypsum). Class D: dangerous residues, originated from the construction process (paints, solvents, oils and others) or those contaminated. Asbestos products.

9 PNRS- Law 12305/2010- Solid Waste National Policy Art. 13. Classification of Solid Waste, according to this law: I Due to the origin: h) Construction and Demolition Waste: residues are those originated from constructions, reformations, repairs and demolitions of civil construction works and those resulting from the preparation and excavation of lands, such as: bricks, ceramic blocks, concrete;

10 PNRS- Law 12305/2010 Session III Solid Waste State Plans Art. 16. Developing the solid waste state plans, for this law, is the condition for the States to have access to the government budget. 3 o Respeitada a responsabilidade dos geradores nos termos desta Lei, as microrregiões instituídas conforme previsto no 1 o abrangem atividades de coleta seletiva, recuperação e reciclagem, tratamento e destinação final dos resíduos sólidos urbanos, civil construction wastes management, de serviços de transporte, de serviços de saúde, agrossilvopastoris ou outros resíduos, de acordo com as peculiaridades microrregionais.

11 PNRS- Law 12305/2010 Session V From the solid waste management plan Art. 20. Subject to preparation of the solid waste management plan : III the civil construction companies, according to the regulations issued by the specific bodies indicated by SISNAMA**; ** Environmental National System

12 PGM CHARACTERISTICS 1st stage: Based on Clean Construction Waste Program (Salvador- BA) resulted on PEL adopted and launched in Goiânia on september nd stage: resulted on Solid Waste Materials Management Project (PGM) - Articulation with the public power and the production sector for the detailing and implantation of the Program.

13 Solid Waste Materials Management Project Composed by a reduction plan, reusing and waste recycling - PmaisL; Reduction must consider all phases and all participants of the waste generation process; At reusing, materials that can be reused are identified and a reusing flow must be encouraged; Recycling depends on the residue quality and appropriate segregation.

14 PILOT PROJECT 1 - OBJECTIVES Construction sites CDW management Cleaner Production (PmaisL) and waste segregation at the source; Strengthening of the National Learning System of the Construction Industry; Public Power answering the obligations established by the 307 CONAMA Resolution.

15 PILOT PROJECT 1 - OBJECTIVES Practice: Implementing the CDW reusing process; Implementing the CDW management projects; The flowing off of segregated wastes; Encourage the development of researches to produce new materials and compounds using recycled aggregates.

16 PILOT PROJECT 1 - IMPLANTATION STEPS

17 IMPLANTATION STEPS Definition of local strategic group and project presentation; Development and implementation of Construction Solid Waste Materials Management Project; Designation of area to receive those segregate waste at construction sites; Residues characterization and analyses (FURNAS); Residues processing (Goiânia Municipality); Recycled aggregates utilization (FURNAS and Federal University of Goiás).

44 Guidebook Clean Waste Program

45 PGM RESULTS OF STAGE 1- GOIÂNIA Guidebook front page: PGM Construction site Management Project

46 Results at the construction sites Organization and cleanness of the construction sites Cleaner constructions Operational people more educated Reduction of number of containers about 40 to 50%

47 Results for the environment Reduction of about 60% to 80% of solid waste from construction and demolition going to landfills and illegally at the environment; Possibility of soil and underground water pollution reduction, with the reduction of wastes irregularly disposal;

48 Results for the environment Possibility reduction of urban drainage impacts, with the irregularly disposal reduction; Possibility reduction of vectors of diseases wich are concentrated in residues irregularly disposal.

49 FINAL REMARKS Engineering challenge to this century is to live in harmony with the environment and the sustainable development is the way to get this goal (MEHTA, 1999).
