2 LIMBAH Pollution and waste should not be put into the environment faster than the environment can degrade and recycle them, or render them harmless. In nature, waste material from an organism usually becomes a meal or resource for another organism. For example, birds will use dead branches or leaves to build their nests; microorganisms and worms in the soil turn leaves and dead animals into humus, which in turn becomes food for plants; and the organic matter in water, such as animal waste or decaying leaves, provides food for aquatic microorganisms. Although these natural cycles have evolved over millions of years, man is rapidly upsetting the balance by producing an ever-increasing amount of waste. Diunduh dari: ……………… 2/12/2012

3 KONSUMSI & LIMBAH The enormous amount of energy and resources that society consumes results in so much garbage that the resulting air pollution, water pollution and acid rain have become serious threats to the global environment. Humans have accumulated more waste than they can properly manage, and may soon be drowning it. In modern society 80 percent of all waste comes from agricultural, industrial or mining activities. The remaining 20 percent comes from households. A large part of what we throw away at home (plastics, metals, paper, glass and organic materials) can be recycled. Concerns about the growing quantities of waste have become even more serious due to the fact that more and more materials have short life cycles. This is especially true of the packaging for everyday products. Waste from Consumption and Production - A threat to natural resources (SUMBER: Diunduh dari: ……………… 2/12/2012

4 SIKLUS HIDUP Waste issues can be better understood by examining the life cycle of the materials that compose it, from extraction to final disposal. Materials are transformed into waste as a consequence of various production and consumption processes. Residual by-products from these transformation processes that are discharged directly into air and water are called emissions. Residuals that are further handled before being discharged are referred to as waste. Once generated, waste may be reused, recycled, transferred for treatment (to reduce its toxicity), incinerated (to reduce its volume) or buried in landfills. Product Life Cycle Sumber: Diunduh dari: ……………… 2/12/2012

Ada empat prinsip umum untuk pengelolaan limbah yang lebih baik dan beberapa cara untuk mengatasi masalah sampah: decrease the consumption of energy and raw materials; recycle  waste materials; reuse  products as many times as possible; burn  waste in order to extract and utilise all potential energy and to diminish their size (incineration); bury  waste in landfills (pits and ditches); and compost  organic matter. However, most waste treatment techniques also have some environmental impacts . Diunduh dari: ……………… 2/12/2012

PENGELOLAAN LIMBAH Pengelolaan sampah adalah pengumpulan, pengangkutan, pemrosesan atau pembuangan, pengelolaan dan monitoring bahan limbah. Istilah ini biasanya berhubungan dengan bahan yang dihasilkan oleh aktivitas manusia, dan proses ini umumnya dilakukan untuk mengurangi efeknya TERHADAP kesehatan, lingkungan atau estetika. Waste management is a distinct practice from resource recovery which focuses on delaying the rate of consumption of natural resources. All wastes materials, whether they are solid, liquid, gaseous or radioactive fall within the remit of waste management Diunduh dari: ……………… 2/12/2012

The Waste Management Continuum has two axes. One is the horizontal stakeholder scale, ranging from municipalities and local governments to the community. The other is the vertical technology scale ranging from high tech/high energy disposal systems to low tech low energy systems. Diunduh dari: ……………… 2/12/2012

8 Process of Waste Management
PEMBUANGAN LIMBAH Historically, efforts in the management of waste have focused primarily on the disposal part of the waste. Whilst there is now a general move towards the recovery of resources from waste, disposal is still the most common form of managing waste. Dumping, landfilling of waste and incineration are some of the most common methods of waste disposal. Process of Waste Management (sumber: Diunduh dari: ……………… 4/12/2012

9 Trash to Cash – Waste Management and Microfinance
WASTE RECYCLING Recycling is the breaking down of materials from waste streams into raw materials, which are then reprocessed either into the same material (closed loop) or a new product (open loop), generally including waste separation and material reprocessing. There are various materials that are capable of being recycled, and technology is advancing to allow the recycling of more materials. The benefits of recycling do not lie solely in diversion of waste away from disposal but, even more importantly, in the reduction of the amount of virgin resources that need to be harvested and processed for the manufacture of new products.

10 WASTE PROCESSING Waste processing is the range of activities characterized by the treatment and recovery (use) of materials or energy from waste through thermal, chemical, or biological means. It also covers hazardous waste handling. Generally, there are two main groups of processes to be considered, (1) Biological processes, such as open composting, enclosed composting, anaerobic digestion, and vermiculture, and (2) Thermal processes, such as incineration, and gasification. Examples of reuse in initiatives include: (1) Product reuse - rethreading tires, recovery of demolition materials, reuse of plastic bags, second hand clothing, reconditioning and repair of furniture and appliances; (2) Materials reuse . Liquid-paper board for seedlings planters, bottles, scrap paper for notes/phone messages, mulching; (3) Durable packaging - e.g. milk crates, bread trays, string or calico shopping bags. Some of the positive effects associated with processed waste include, more effective use of resources, employment opportunities in the service and repair industries, support for charity based stores, better protection of products as durable packaging is more robust, and changes in attitudes towards disposable products.

11 WASTE MINIMIZATION Waste minimization is aimed at reducing the production of waste through education and improved production process rather than aiming to increase technology to improve treatment of waste. The idea of minimization is not centered on technological advances, it can be viewed a method of managing existing resources and technology in order to maximise the efficiency of available resource use. Minimizing waste generation has the potential to reduce costs or increase profits by maximizing the use of resources and by reducing the amount of waste to be disposed of the cost of waste management is also decreased. Waste avoidance for individuals: Buying goods in bulk; reconsidering superfluous purchases; purchasing products in materials/packaging that is readily recycled; use of alternatives, e.g. landscaping that creates mulched gardens in place of lawns; and use of composting and vermiculture practices. Waste minimization in industry: Change in product design to reduce materials consumption; using crates instead of pallets to avoid the need for shrink wrap; incorporate Eco-Design technology into production processes; adoption of Cleaner Production practices that ensure avoidance through efficiency measures; and conduct regular audits and monitoring of waste reduction/resource recovery practices. Waste minimization for Local Government: Encourage community 'avoidance' activities, e.g. promote competitions rewarding initiative in this area of resource recovery; lead by example, e.g. display mulched gardens throughout the municipality; and provide facilities and infrastructure to assist industry, business and the community to undertake resource recovery practices, e.g. kerbside recycling and resource exchange registers, initiate greener procurement programmes.

The waste hierarchy refers to the 3Rs of Reduce, Reuse and Recycle, which classify waste management strategies according to their desirability, and are meant to be a hierarchy in order of importance. Upcycling is the process of converting waste materials or useless products into new materials or products of better quality or a higher environmental value. The goal of upcycling is to prevent wasting potentially useful materials by making use of existing ones. Diunduh dari: ……………… 4/12/2012

13 WASTE HIERARCHY The waste hierarchy is a guide when determining the Best Practicable Environmental Option and represents a chain of priority for waste management, extending from the ideal of prevention and reduction to the last resort of disposal. The waste hierachy shows that waste prevention, or minimisation, are the preferred options as they minimise waste generation and ultimately waste disposal.  Recycling and composting are lower in the waste management hierarchy, as these options both require additional energy and resources to reduce waste levels.

What do we mean by wastewater? Wastewater can mean different things to different people with a large number of definitions in use. In the broad perspective, wastewater is “a combination of one or more of: Domestic effluent consisting of black-water (excreta, urine and faecal sludge) and greywater (kitchen and bathing wastewater); Water from commercial establishments and institutions, including hospitals; Industrial effluent, stormwater and other urban run-off; Agricultural, horticultural and aquaculture effluent, either dissolved or as suspended matter (adapted from Raschid-Sally and Jayakody, 2008). Wastewater management encompasses a broad range of efforts that promote effective and responsible water use, treatment, and disposal and encourage the protection and restoration of our nation's watersheds.

Misalnya, aluminium merupakan komoditas yang melimpah pada produk konsumsidan ditemukan pada pembuangan sampah. Aluminium juga merupakan sumberdaya yang dapat di daur ulang. Perlahan-lahan, bahan-bahan lain dari sampah akan menjadi lebih berharga. Sekitar lima hingga sepuluh persen dari produksi minyak global disuling dan berubah menjadi plastik, yang sekarang digunakan dalam banyak produk. Hal ini telah menghasilkan konten plastik yang tinggi dan berasal dari sampah. Seiring dengan waktu, dan terutama jika kenaikan harga minyak terus melambung, sampah dapat menjadi sumber plastik daur ulang dan bahan mentah lainnya. Diunduh dari: ….

Kalau harga minyak minigngkat, aluminium dan bahan-bahan lain yang berasal dari sampah juga meningkat, maka tingkat pemilahan sampah juga akan meningkat. Selain meningkatnya permintaan komoditas secara global dan potensi kenaikan harga sumberdaya alam, inisiatif hijau juga cenderung mendukung daur ulang sampah lebih lanjut dan inisiatif minimisasi sampah. Kota dan masyarakat cenderung untuk memperkenalkan perilaku lebih ekologis dalam pengelolaan limbah seiring dengan waktu. Masyarakat juga akan cenderung lebih memilah-milah sampah di tempat tinggalnya dan di lokasi komersial , sehingga lebih mudah memfasilitasi usaha pengelolaan sampah. Diunduh dari: ….

25 Waste to Watts: How Today's Garbage Can Be Tomorrow's Electricity
Membakar sampah adalah sesuatu hal yang biasa dilakukan untuk menghilangkan sampah. Insinerator tua yang dibangun beberapa dekade yang lalu adalah mimpi buruk bagi lingkungan . Mereka melepaskan ke lingkungan sejumlah besar emisi toksik dalam bentuk dioksin , furan , dan logam beracun seperti merkuri . Tetapi insinerator modern dewasa ini dilandasi oleh hukum lingkungan untuk mengekang pelepasan polutan toksik ke udara. Teknologi insinerator sudah jauh lebih baik . Teknologi baru membakar sampah sampai dengan derajat Fahrenheit . Pada suhu itu, ikatan molekul dalam bahan kimia toksik akan rusak. Hal ini secara signifikan mengurangi emisi gas limbah pembakaran . Gas buang kemudian dapat digunakan untuk menghasilkan uap untuk menghasilkan listrik . Gas buang ini kemudian diproses lebih lanjut untuk menghilangkan sebagian besar kontaminan toksiknya. Akibatnya , insinerator saat ini telah mengurangi emisi gas toksik sekitar 99,9 % dibandingkan teknologi insinerator beberapa dekade yang lalu . Diunduh dari: ….
