How to recycle and dispose of waste properly

The federal Environmental Protection Agency sets national policy, publishes guidance and tracks the data, but it does not run collection. Your materials are collected under a contract between a local government and a hauler, and delivered to a materials recovery facility whose equipment determines what can physically be sorted.

That equipment is why rules differ. A facility with optical sorters that separate plastics by resin type can accept a wider range than one relying on manual picking. A facility with a glass processing line accepts glass; one without it will tell you glass is not recyclable there, which is true locally even though glass is endlessly recyclable in principle.

Market conditions change the list too. A material is only recyclable if someone will buy the sorted output, and when a commodity market collapses, cities drop that material from their accepted list at short notice. Mixed rigid plastics and some paper grades have moved in and out of acceptance for exactly this reason.

So the authoritative source is your own city or county solid waste department, usually reachable through the municipal website with a search for recycling or solid waste. Most publish a one-page accepted materials list, and many run a searchable lookup where you type an item and it tells you which bin.

If you rent, ask the landlord or building manager which hauler serves the property and whether recycling is collected at all, because it is not universal — particularly in multi-family buildings, where participation is lower and some jurisdictions do not require it.

Check collection days, whether recycling is weekly or fortnightly, whether bins must be at the kerb by a set time, and whether the container must be a specific colour or issued by the city. Fines for wrong-day or wrong-container presentation exist in some places, and bins left out are a common minor violation.

Learn the local words. Kerbside single-stream means everything recyclable goes in one bin and is sorted at the facility. Dual-stream separates fibre from containers. Drop-off means you take material to a site yourself. Deposit return applies in the states with bottle bills, where certain containers carry a refundable deposit redeemed at a redemption centre or machine.

Finally, remember the hierarchy the EPA actually promotes: prevention first, then reuse, then recycling, then energy recovery, then disposal. Recycling is fourth in that order. The bottle not bought is worth more than the bottle correctly sorted, which is unglamorous but is the part with the largest effect.

The core accepted list is consistent almost everywhere: corrugated cardboard, paperboard such as cereal boxes, newspaper, office paper and mail, metal food and drink cans, and plastic bottles and jugs with a neck. Glass bottles and jars are accepted in many places but not all.

The reliably problematic categories are less obvious. Plastic bags and film jam the rotating screens at sorting facilities and are the single most disruptive contaminant — they must go to a store drop-off point where those exist, never in the kerbside bin. Anything long and flexible causes the same problem, which is why garden hoses, cables, chains and string are known in the industry as tanglers.

The four habits worth fixing are these. First, do not bag your recycling — many facilities treat a sealed bag as trash and divert it unopened. Second, empty and rinse containers, because food residue contaminates paper it touches and greasy paper cannot be recycled. Third, do not put small items in loose, since anything below a few inches falls through the screens and is lost regardless. Fourth, do not flatten or nest containers unless told to, because nested items are misidentified by sorters.

Pizza boxes are the classic argument and the answer is now more permissive than folklore suggests: the fibre is recyclable and small amounts of grease are tolerated by many mills, but a box saturated with oil and cheese is not. Tear off and recycle the clean lid, bin the soaked base if it is genuinely soaked.

Cartons — the paper-and-plastic laminate used for milk, juice and stock — are accepted in many programmes and not others, because they need a specialised mill. Check yours specifically rather than assuming.

Wishcycling is the term for placing an item in the bin because you hope it can be recycled. It is well-intentioned and it is the mechanism by which loads get downgraded or rejected. The correct rule when genuinely unsure is to put the item in the trash, and it feels wrong to almost everyone.

Some items are worse than merely useless. Needles and syringes injure sorting line workers. Propane cylinders and aerosols explode. Batteries ignite. Nappies and pet waste contaminate everything they touch. None of these belong in a recycling bin under any circumstances.

If your city offers a searchable item lookup, use it once for the twenty items you handle most often and then stop guessing. A single ten-minute session settles most household disputes permanently.

Batteries first, because they are the most urgent. Lithium-ion cells — in phones, laptops, power tools, e-cigarettes, toothbrushes, greetings cards that play music, and anything rechargeable — ignite when crushed or punctured. Truck and facility fires from batteries are frequent and have destroyed sorting plants. Take them to a retailer collection point or a household hazardous waste site, and tape the terminals of loose cells before transporting them.

Electronics go to e-waste collection: retailers with take-back programmes, manufacturer mail-back schemes, municipal e-waste days, and permanent drop-off sites. Many states have laws requiring manufacturers to fund collection, which is why it is usually free. Wipe or destroy the data before handing anything over, and remove batteries where they are removable.

Paint, solvents, adhesives, pesticides, pool chemicals, motor oil, antifreeze and cleaning products are household hazardous waste. Every county has a route for these — a permanent facility, periodic collection events, or in some cases retailer take-back for oil and paint. Never pour them down a drain or on the ground, and never put liquid containers in the kerbside bin.

Latex paint is the common exception worth knowing: many jurisdictions allow fully dried-out latex paint in the regular trash with the lid off, and it can be dried by leaving it open or adding an absorbent. Oil-based paint is hazardous waste regardless of state.

Fluorescent tubes and compact fluorescent bulbs contain small amounts of mercury and should go to a recycling drop-off rather than the bin. If one breaks, the EPA publishes a specific cleanup procedure — ventilate the room, do not vacuum, collect fragments with stiff card and sticky tape. LED bulbs contain no mercury and are treated differently.

Medicines go to a drug take-back location — pharmacies, many police stations, and periodic national take-back days — rather than the toilet or the bin. Sharps and needles go in an approved sharps container and then to a designated collection point, never loose in any bin.

Propane cylinders, aerosols that are not empty, fire extinguishers and ammunition all need specific handling and are genuinely dangerous in a collection truck. Ask the county rather than guessing.

Tyres, motor oil and car batteries usually go back to a retailer or service centre, frequently free, because sellers are commonly required to accept them. Ask when buying replacements and hand the old ones over at the same time.

Food is the largest single component of what American households send to landfill, and it is the stream with the clearest household-level fix. Buried food waste decomposes without oxygen and generates methane, which is why landfill diversion of organics is a policy priority in a growing number of states and cities.

The cheapest intervention is not composting but not wasting: planning purchases, storing produce properly, understanding that most date labels are quality indicators rather than safety deadlines, and using what is already in the house. This also saves money directly, which is a rare alignment.

Where a city runs an organics collection, use it. Programmes typically accept food scraps, sometimes including meat and dairy that home composting cannot handle, along with garden waste and occasionally certified compostable serviceware. The accepted list is narrower than people assume and contamination with plastic is the main problem.

Home composting works in a garden and in far smaller spaces than people think. A basic outdoor pile needs a mix of nitrogen-rich green material — fruit and vegetable scraps, coffee grounds, grass — and carbon-rich brown material such as dry leaves, cardboard and paper, kept damp and turned occasionally.

Avoid meat, fish, dairy, oils and pet waste in a home pile: they attract animals, smell, and do not reach temperatures that break them down safely. These are the things a municipal programme can take and a garden heap cannot.

In an apartment, options are a worm bin, a sealed indoor bokashi system, a countertop collector emptied into a community drop-off, or a subscription collection service. Farmers' markets in many cities accept household food scraps at no charge, which is the simplest route for people with no outdoor space.

Be sceptical of compostable packaging. Most of it requires industrial composting conditions that a home pile never reaches and that only some municipal facilities provide. Compostable plastics in a recycling bin are a contaminant, and in a landfill they behave much like ordinary plastic.

Finished compost takes months and produces a genuinely useful soil amendment. If you have no use for it, community gardens, allotments and neighbours generally will take it.

Furniture, mattresses, appliances and construction debris are not kerbside items. Most cities run a bulky waste collection — sometimes free a set number of times a year, sometimes for a fee, usually requiring an appointment booked in advance. Fly-tipping on the pavement is enforced and fined in most jurisdictions.

Appliances containing refrigerants — fridges, freezers, air conditioners, dehumidifiers — must have those refrigerants professionally recovered before disposal, which is why they cannot simply be put out. Many utilities run appliance recycling programmes that collect an old working fridge or freezer free and sometimes pay a rebate, because removing an inefficient second fridge reduces demand on the grid.

Mattresses are increasingly covered by state recycling programmes funded by a fee charged at purchase, with free drop-off or collection. Where no programme exists, expect to pay a disposal fee, and check whether the retailer delivering a new mattress will take the old one.

Moving out is where most people generate their largest single volume of waste and make their worst decisions. Start four weeks out, not the last weekend. Donate usable furniture, clothing and household goods to charities that collect, several of which will take bulky items from the house free because they resell them.

Sell or give away rather than dump wherever possible. Local free-to-collector groups clear items within hours that would otherwise cost a collection fee, and this is by far the fastest disposal route for anything usable.

For a genuinely large clearance, compare a rented skip or dumpster against a junk removal service. A skip is cheaper per volume if you can load it yourself and have somewhere legal to put it, which may need a permit if it stands on a public street. A removal service costs more but does the labour and sorts recyclables and donations out.

Construction and renovation debris usually cannot go in household collection at all and must go to a transfer station or construction and demolition facility, where it is charged by weight. Clean, separated material — wood, metal, concrete, gypsum — is frequently cheaper to tip than a mixed load, so separating as you demolish saves money.

Keep a record if a landlord will be inspecting. Photographs of a cleared property, and the receipt from a licensed hauler, are the evidence that prevents disposal costs being taken out of a security deposit.
