Construction and demolition (C&D) waste is not a monolithic waste stream, but it is a family of waste streams. Therefore, it is important to define the types of materials, which could be available in C&D waste. The most common materials could be paper/cardboard, garden/vegetation, wood/timber, carpets, other textiles, rubber, glass, plastics, metals, hazardous wastes, ceramics, soil/rubble <150mm, cobbles/boulders, clean soil, concrete, plasterboard, bricks, asphalt/bitumen,
cement sheet, insulation and others. Based on the local information and pilot surveys, a list of materials are prepared as we took 9 samples from 9 kebeles and there are 90 construction sites in the city. After we took the samples and the number of days the construction needed to be finished we get the annual value of the waste
generated in the site.
Modern urban living generates a large variety of solid wastes that cannot be
assimilated in the city environment. Nairobi is no exception, with each of its
estimated 3.5 million residents generating approx. 600 g of solid waste every
day. Large improvements in urban cleanliness and health were realized when
organized collection of solid waste and its disposal outside of city limits were
introduced in European cities in the late 19th century. In Nairobi, only half of
the estimated 3000 ton of waste generated every day is collected. To prevent environmental degradation from the large dumpsites then arising, the practice of sanitary landfilling was invented, and more recently, it has been realized that state-of-the-art incinerators, whilst much more costly to operate, offer an even lower environmental footprint. Nairobi has no means of safe disposal, and approx. 850 tons of its waste reaches the Dandora dumpsite everyday, and it has been documented that this dumpsite is negatively affecting the health of thousands of Nairobi residents. 2/3 of the waste generated in Nairobi is hard to account for.
It has always been true that one person’s waste can be another person’s
resource. Modern approaches to solid waste management incorporate strategies
to reduce waste generation, to encourage re-use, and to enable recycling of
materials and recovery of energy on an industrial scale. In Nairobi, more than
2000 people earn a living through their engagement in resource recovery,
but at less than 200 ton per day of recyclable material recovered, they
account for only about 7% of the waste stream. Recycling rates of the order of
20% are achieved in many other contemporary cities.
This document provides a summary of the outputs of the training session on
target setting and stakeholder engagement which was held as part of the project
developing an integrated solid waste management plan for the city of Nairobi.
Three key outputs from the workshop are: a set of high level objectives which represent the motivation for
developing the plan; a list of stakeholder issues which were established through a role playing exercise by the participants; and a set of preliminary targets for the ISWMP. It is suggested that the high level objectives should be further refined by the NTT
(to remove duplication and ambiguity), be presented to stakeholders, and used
to help shape the ISWMP.
The situational background to Solid Waste Management in Nairobi City is drawn and analysed at from a basic systems perspective to allow for the development of more holistic interventions to the problems and challenges highlighted in the ISWM planning process to this point. The data utilised to this end is sourced from a diversity of sources including; previous research work on solid waste management in Nairobi and other areas, preliminary zone surveys and waste characterisation audits carried out in Nairobi in 2009, UNEP/CCN ISWM Training and Stakeholder Workshops held in Nairobi through 2009, and public and private reports. It is hoped that from this contextual lens, the specific ISWM actions proposed and summarised in the main ISWM Draft Plan document can be better understood and seen to follow
from a natural sequence and thread of considerations.
As a part of the ISWM Plan fourteen schemes have been proposed for the city of Novo Hamburgo. The major schemes identified under the ISWM Plan were based on the goals and targets set under the Strategic Action Plan. These schemes will provide the support mechanism through which the ISWM plan will be implemented. Some
of these activities will require new technologies, equipment, infrastructure and human resources while others can be implemented under the existing mechanisms. They will also need the backing and facilitation from the important institutions that are involved in Solid Waste Management. This document is also an involving document.
The modification and changes strategic actions under ISWM Plan, to take up the emerging challenges such as special wastes, will also lead towards the development of new schemes and modifications in the current schemes.
