Reciclar implica procesar materiales usados en nuevos productos para evitar el desperdicio de materiales potencialmente útiles, reducir el consumo de materias primas frescas, reducir el uso de energía, reducir la contaminación del aire (de la incineración) y la contaminación del agua (del vertido) al reducir la necesidad de eliminación de desechos «convencionales» y menos emisiones de gases de efecto invernadero en comparación con la producción virgen. Los materiales reciclables incluyen muchas clases de vidrio, papel, metal, plástico, textiles y electrónica. Aunque es similar en efecto, el compostaje u otra reutilización de residuos biodegradables, como alimentos o residuos de jardín, no se considera reciclado. Los materiales que se reciclarán serán llevados a un centro de recolección o recogidos de la acera, luego clasificados, limpiados y reprocesados en nuevos materiales destinados a la fabricación. En sentido estricto, el reciclaje de un material produciría un nuevo suministro del mismo material, por ejemplo, papel de oficina usado para más papel de oficina, o poliestireno expandido usado para obtener más poliestireno. Sin embargo, esto suele ser difícil o demasiado caro (en comparación con producir el mismo producto a partir de materias primas u otras fuentes), entonces el «reciclado» de muchos productos o materiales implica su reutilización para producir diferentes materiales (por ejemplo, cartón).
Otra forma de reciclaje es la recuperación de ciertos materiales de productos complejos, ya sea por su valor intrínseco (por ejemplo, plomo de baterías de automóvil u oro de componentes de computadora) o debido a su naturaleza peligrosa (por ejemplo, eliminación y reutilización de mercurio de varios artículos). Los críticos cuestionan los beneficios económicos y ambientales netos del reciclaje sobre sus costos, y sugieren que los defensores del reciclaje a menudo empeoran las cosas y sufren un sesgo de confirmación. Específicamente, los críticos argumentan que los costos y la energía utilizados en la recolección y el transporte restan (y superan) los costos y la energía ahorrados en el proceso de producción; también que los trabajos producidos por la industria del reciclaje pueden ser un comercio pobre para los trabajos perdidos en la explotación forestal, la minería y otras industrias asociadas con la producción virgen; y que los materiales como la pulpa de papel sólo se pueden reciclar algunas veces antes de que la degradación del material impida su posterior reciclaje. Los defensores del reciclaje cuestionan cada uno de estos reclamos y la validez de los argumentos de ambos lados ha llevado a una duradera controversia.

Las 3R significan: Reducir, Reutilizar y Reciclar.
Esto nos enseña un conjunto de ideas para ayudarnos a conservar los recursos y disminuir las pilas de residuos que se envían diariamente a los vertederos de todo el mundo. La naturaleza funciona en un ciclo para que el desperdicio se convierta en alimento para otros sistemas vivos y deberíamos hacer lo mismo.

Cuando se trabaja con plásticos, a menudo existe la necesidad de identificar qué material plástico particular se ha utilizado para un producto determinado. La mayoría de los consumidores reconocen los tipos de plásticos mediante el sistema de codificación numérica creado por la Society of the Plastics Industry [Sociedad de industria plástica] a finales de los años ochenta. Hay seis tipos diferentes de resinas plásticas que se usan comúnmente para empacar productos para el hogar. Los códigos de identificación que figuran a continuación se pueden encontrar en la parte inferior de la mayoría de los envases de plástico.

En la primavera de 1970, Gary Dean Anderson, un estudiante de 23 años de la Universidad del Sur de California, desarrolló el primer logo de reciclaje. Como resultado, se llevó a casa el primer premio de una beca de matrícula de $2.500.

- Ahorra recursos naturales: Al fabricar productos a partir de materiales reciclados en lugar de materiales vírgenes, conservamos la tierra y reducimos la necesidad de perforar en busca de petróleo y cavar en busca de minerales.
- Ahorra energía: Generalmente se necesita menos energía para fabricar productos reciclados; el aluminio reciclado, por ejemplo, consume un 95% menos de energía que el nuevo aluminio del mineral de bauxita.
- Ahorra aire y agua limpios: En la mayoría de los casos, fabricar productos a partir de materiales reciclados crea menos contaminación del aire y del agua que los productos vírgenes.
- Ahorra espacio en el relleno sanitario: Cuando los materiales que recicla entran en nuevos productos, no van a parar a vertederos o incineradores, por lo que se conserva el espacio de los vertederos.
- Ahorra dinero y crea empleos: El proceso de reciclaje crea muchos más trabajos que los vertederos o incineradores y el reciclaje puede ser con frecuencia el método de gestión de residuos menos costoso para las ciudades y los pueblos.

Lata de aluminio
El aluminio: está hecho de un recurso natural llamado mineral de bauxita. Este mineral se encuentra en las rocas y tiene que ser extraído. No es un recurso renovable, lo que significa que una vez que se haya desaparecido, no tendremos más. Pueden transcurrir entre 80 y 100 años para que una lata de aluminio se descomponga cuando va a un vertedero. El aluminio se puede reciclar en envases y recipientes (bebidas, alimentos), materiales de construcción, construcción de automóviles y aviones, electrodomésticos (estufas, refrigeradores), juguetes, marcos para cuadros, decoración para el hogar (cuencos, jarrones, etc.), bates de béisbol y más . El aluminio se tritura y se descontamina, se derrite y se vierte en moldes. Todo el proceso toma alrededor de 90 días. Se puede reciclar una y otra vez para siempre. Reciclar aluminio utiliza un 96% menos de energía de la que se necesita para producir la misma cantidad de aluminio a partir de las materias primas. El 95% de los contaminantes del aire se eliminan y el 100% de los residuos sólidos se guardan en los vertederos. Reciclar una lata de aluminio ahorra suficiente electricidad para operar un televisor por hasta 3 horas.
Plásticos
Los plásticos generalmente se clasifican por uno de los siete números que se encuentran dentro de las flechas que se persiguen, comúnmente llamado el símbolo de reciclaje. El número de símbolo de reciclaje identifica el tipo de plástico utilizado para fabricar el artículo. Sin embargo, esto no significa que pueda colocarse en su contenedor de reciclaje para su recompra o reciclaje.
PETE o PET #1
Ejemplos de recompras: botellas de agua y botellas de refrescos (generalmente transparente y vienen en diferentes colores). Este es el contenedor de plástico más reciclado. Las botellas se pueden clasificar por color y se muelen y se lavan. A diferencia del polietileno, el PET se hunde en el agua de lavado, mientras que las tapas de plástico y las etiquetas flotan. El copo limpio se seca y usualmente se repeleja. El PET reciclado tiene muchos usos y un mercado bien establecido para esta resina útil. Realmente, el uso más grande es en textiles. Las empresas de alfombras a menudo pueden usar resina 100% reciclada para fabricar alfombras de poliéster en una variedad de colores y texturas. El PET también se hila como algodón de azúcar para fabricar relleno de fibra para almohadas, edredones y chaquetas. El PET también se puede enrollar en hojas transparentes o cinta para VCR y casetes de audio. Además, una cantidad sustancial vuelve al mercado de las botellas. Todos los programas de reciclaje aceptan este plástico. Ejemplos de no recompras: las botellas de aceite de cocina, los frascos de mantequilla de maní y los recipientes para aderezo de ensalada deben colocarse en una bandeja de reciclaje general.
HDPE #2
All curbside recycling programs accept this container if it has a narrow neck. Milk, detergent and oil bottles, toys and plastic bags. HDPE is called natural since that is it's natural color, and it is the most valuable because it can be made into any color when it is recycled. Other products are often packed in brightly colored bottles which are mixed together at recycling plants into mixed color or rainbow bales. Most of this material is later dyed black after it is processed. Recycling HDPE is a pretty simple process. The bales are broken apart and ground into small flakes. These flakes are then washed and floated to removed and heavy (Sinkable) contaminants. This cleaned flake is then dried in a stream of hot air and may be boxed and sold in that form. More sophisticated plastic plants may reheat these flakes, add pigment to change the color and run the material through a pelletizer. This equipment forms little beads of plastic that can then be reused in injection molding presses to create new products. Some end uses for recycled HDPE are plastic pipes, lumber, flower pots, trash cans, or formed back into non food application bottles. Buy back examples: opaque gallon and 2.5 gallon water jugs and opaque juice containers. It takes 1.75 kilograms of petroleum (in terms of energy and raw materials) to make one kilogram of HDPE. HDPE is commonly recycled, and has the number "2" as its recycling symbol. In 2007, the global HDPE market reached a volume of more than 30 million tons. Non buy back examples: cooking oil, peanut butter jars and salad dressing containers should be put into a general recycling bin.
V or PVC
Food wrap, vegetable oil bottles, blister packages. PVC is not typically recycled due to the prohibitive cost of regrinding and recompounding the resin compared to the cost of virgin (unrecycled) resin. Some PVC manufacturers have placed vinyl recycling programs into action, recycling both manufacturing waste back into their products, as well as post consumer PVC construction materials to reduce the load on landfills. The thermal depolymerization process can safely and efficiently convert PVC into fuel and minerals, according to the company that developed it. It is not yet in widespread use. A new process of PVC recycling is being developed in Europe called Texiloop. This process is based on a technology already applied industrially in Europe and Japan, called Vinyloop, which consists of recovering PVC plastic from composite materials through dissolution and precipitation. It strives to be a closed loop system, recycling its key solvent and hopefully making PVC a future technical nutrient.
LDPE
Many plastic bags. Shrink wrap, garment bags. It in chemically similar to HDPE but it is less dense and more flexible. Most polyethylene film is made from LDPE which you often see as plastic bags and grocery sacks. This scrap may be clear or pigmented and it is hand sorted and baled at recycling processing plants. Recycling LDPE is very similar to HDPE except special grinders are used to handle the thin films. The films are often washed and repelletized or used directly to make new products. Some end uses for recycled LDPE are plastic trash bags and grocery sacks, plastic tubing, agricultural film, and plastic lumber.
PP
Refrigerated containers, some bags, most bottle tops, some carpets, some food wrap. Polypropylene is often used for food containers, particularly those that need to be dishwasher safe. The melting point of polypropylene is very high compared to many other plastics, at 320°F (160°C), which means that the hot water used when washing dishes will not cause polypropylene dishware to warp. This contrasts with polyethylene, another popular plastic for containers, which has a much lower melting point. Polypropylene is also very easy to add dyes to, and is often used as a fiber in carpeting which needs to be rugged and durable, such as the carpet one finds around swimming pools or paving miniature golf courses. Unlike nylon, which is also often used as a fiber for rugged carpeting, polypropylene doesn't soak up water, making it ideal for uses where it will be constantly subject to moisture. Research is ongoing with polypropylene, as makers experiment with different methods for synthesizing it. Some of these experiments yield the promise of exciting new types of polypropylene, with new consistencies and a different feel from the fairly rigid version we are all used to. These new elastic versions of polypropylene are very rubbery, making them even more resistant to shattering and opening up many different uses for an already pervasive plastic. Polypropylene is not as sturdy as polyethylene, but it has benefits that make it the better choice in some situations. One of these situations is creating hinges from a plastic, such as a plastic lid on a travel mug. Over time, plastics fatigue from the repetitive stress of being opened and shut, and eventually will break. Polypropylene is very resistant to this sort of stress, and is the plastic most often used for lids and caps which require a hinging mechanism. Like many plastics, polypropylene has virtually endless uses, and its development has not slowed since its discovery. Whether used for industrial molds, rugged currency, car parts, or Tupperware, polypropylene is one of a handful of materials the world is literally built around.
PS
Throwaway utensils, meat packing, protective packing. Currently, the majority of polystyrene products are not recycled because of a lack of consumer awareness regarding suitable recycling facilities and collection methods. Expanded polystyrene scrap can be easily added to products such as EPS insulation sheets and other EPS materials for construction applications. Commonly, manufacturers cannot obtain sufficient scrap because of the aforementioned collection issues. When it is not used to make more EPS, foam scrap can be turned into clothes hangers, park benches, flower pots, toys, rulers, stapler bodies, seedling containers, picture frames, and architectural molding from recycled PS. Recycled EPS is also used in many metal casting operations. It can be combined with cement to be used as an insulating amendment in the making of concrete foundations. American manufacturers have produced insulated concrete forms made with approximately 80% recycled EPS since 1993. However, polystyrene recycling is not a closed loop, producing more polystyrene; polystyrene cups and other packaging materials are instead usually used as fillers in other plastics, or in other items that cannot themselves be recycled and are thrown away.
Other (Plastic #7)
This plastic category, as its name of “other” implies, is any plastic other than the named #1-#6 plastic types. OTHER usually layered or mixed plastic. No recycling potential - must be land filled. These symbols are meant to indicate the type of plastic, not its recyclability. Types 1 and 2 are commonly recycled. Type 4 is less commonly recycled. The other types are generally not recycled, except perhaps in small test programs. Common plastics polycarbonate (PC) and acrylonitrile-butadiene-styrene (ABS) do not have recycling numbers. Chemical engineers will say that there are many more types and uses for polymers. But most debate in recycling focuses on these seven categories. These containers can be any of several different types of plastic polymers. Some curbside recycling programs accept this container if it has a narrow-neck. Common uses: 3 and 5 gallon reusable water bottles.
Bi-metal
Bi-metal is actually made from steel with a thin plating of tin. You can often tell one of these cans by placing a magnet next to it. If the magnet sticks, the can is most likely bi-metal. Steel and tin, as well as other metals are all natural resources. This means that we have to mine the materials to make them from the ground and that eventually they will be gone. For every ton of steel recycled, 2,500 pounds of iron ore, 1,400 pounds of coal, and 120 pounds of limestone are conserved. Steel can be used for more cans, cars, appliances, and construction materials
Glass
Most ready-to-drink beverages purchased in glass containers are part of the CRV program which requires that the lids be removed from the glass containers. It is important that glass bottles be sorted by these colors: clear, brown and green.
The use of recycled glass as aggregate in concrete has become popular in modern times, with large scale research being carried out at Columbia University in New York. This greatly enhances the aesthetic appeal of the concrete. Recent research findings have shown that concrete made with recycled glass aggregates have shown better long term strength and better thermal insulation due to its better thermal properties of the glass aggregates. Mixed glass waste streams can also be recycled and converted into an aggregate. Mixed waste streams may be collected from materials recovery facilities or mechanical biological treatment systems. Some facilities can sort out mixed waste streams into different colors using electro-optical sorting units.
Many cities do curb-side recycling, meaning that they collect household recyclable waste on a weekly or bi-weekly basis that residents set out in special containers in front of their homes. Apartment dwellers usually use shared containers that may be collected by the city or by private recycling companies which can have their own recycling rules.
In some cases, glass is specifically separated into its own container because broken glass is a hazard to the people who later manually sort the co-mingled recyclables. Sorted recyclables are later sold to companies.
In 1971, the state of Oregon passed a law requiring buyers of carbonated beverages (such as beer and soda) to pay five cents per container as a deposit which would be refunded to anyone who returned the container for recycling. This law has since been copied in nine other states including New York and California. The abbreviations of states with deposit laws are printed on all qualifying bottles and cans. In states with these container deposit laws, most supermarkets automate the deposit refund process by providing machines which will count containers as they are inserted and then print credit vouchers that can be redeemed at the store for the number of containers returned. Small glass bottles (mostly beer) are broken, one-by-one, inside these deposit refund machines as the bottles are inserted. A large, wheeled hopper (very roughly 1.5m by 1.5m by 0.5m) inside the machine collects the broken glass until it can be emptied by an employee. \
All glass containers can be recycled.
Steel
The familiar "tin" can has been part of our society for more than a century. Steel cans package a variety of products, including fruits, vegetables, soups, sauces, meats, condiments, juice, pet food, cleaning products, paint, shoe polish, adhesive bandages, coffee and even cookies. Steel cans are also something else -- recyclable. And they have the potential to be recycled over and over again into new steel products.

Uncoded Plastics are plastic consumer goods not identified by code numbers and are not usually collected. Plastic tarps, pipes, toys, computer keyboards, and a multitude of other products simply do not fit into the numbering system that identifies plastics used in consumer containers. There are actually thousands of different varieties of plastic resins or mixtures of resins. These are developed to suit the needs of particular products. There is limited recycling of some of these specific plastic products in truckload quantities from industrial sources. No one has entered the business of collecting a variety of these plastics in small quantities.

Turn a plastic water bottle into a decorative lighthouse -- just the thing to brighten up a rainy summer day.
Materials
- 1.5-liter sport water bottle
- Craft knife
- Aluminum foil
- Red acrylic paint
- Black tape
- Play-Doh or clay
- Flashlight
- White craft foam
- Clear packing tape
Total Time Needed: 1 Hour
Instrucciones
- Use a craft knife (adults only) to cut the bottle in half. Glue aluminum foil inside the cone-shaped portion of the top half (this creates a reflective dome), then use red acrylic paint to coat the outside of the foil-lined section.
- When the paint is dry, apply 3-inch vertical strips of black tape, spaced evenly, around the unpainted portion of the bottle top.
- In the bottom half of the bottle, pack a baseball-sized ball of Play-Doh or clay. Stand a flashlight upright in the clay and press down to secure it in place. Cut a notch down from the bottle's edge to allow access to the flashlight's switch, as shown.
- Next, wrap an 11 1/2- by 10-inch sheet of white craft foam around the bottom half of the bottle (the foam will extend about 4 inches above the bottle) and note approximately where the flashlight switch opening is. Remove the foam and cut out a switch opening. Re-wrap the foam around the bottle and secure the overlapping ends with clear packing tape.
- Finally, fit the cut edge of the bottle top just inside the foam sleeve and securely tape the foam to the bottle with colored tape.

An ocean in a bottle is fairly quick and simple to make. Since "quick & simple" is my middle name, this project was one of my favorites as a kid. Five minutes' work will yield an attractively hypnotic "ocean." It's also a fun use and a second chance for an old plastic bottle.
Things You'll Need:
- plastic bottle
- water
- food coloring
- oil
Instructions
- Once you have your materials, remove the label from the bottle. You may need scissors for this. Or not. Next, fill the bottle about half way up with water and decide what color you want it to be. I was out of red and yellow, so I settled on a teal hue (two drops green, three blue). Add the food coloring and give the bottle a light swirl to mix.
- Here's where that funnel is going to come in handy. Slowly fill the rest of the bottle with your oil. The funnel with prevent the oil from getting all over the outside of your bottle and rendering it hopelessly slippery (I know from experience). Come as close to the top as possible without spilling.
- Now to seal in the goodness. Basically you're just going to screw on the cap as tight as you can. I put some glue on the threads of the bottle before closing as added insurance. You can also wrap some electrical/duct tape around the cap as further protection against leaks if you feel so inclined.
