Tumble bricks in [[Cement mixing|mixer]] to produce dust. Add brick dust to [[Mortar Mixes|cement mixes.]]\n* Red brick dust colours concrete\n* Brick dust & grit can be used in [[Papercrete|papercrete]]\n\n===Broken tiles===\n* Smash with a [[Hammers|hammer]], use the small pieces for mosaic work, eg a mosaic border. Put tiles upside down when breaking.\n* Tumble tiles in [[Cement mixing|mixer]] with a brick (or other hard weight) to produce dust and small aggregate. Mix into [[Mortar Mixes|concrete]] for indoor use as porous aggregate.\n\n===Milk Bottles===\n\n* Cut the base off to make both a small tray and a water-scoop.\n* Cut a hole in the side, near the bottom :-\n** Without the lid, fit over a bath-tap to help filling a large bucket,\n** With the lid pierced as a force-fit to a plastic tube, use similarly or otherwise to re-route dripping water.\n* Skittles, vases, etc.\n\n===[[Pozzolan]]s===\n* These react with [[Mortar Mixes|cement]] to increase set strength. They thus permit reduced cement use. \n* Upto 30% of cement powder may be substituted with a [[Pozzolan|pozzolan]].\n* Pozzolan needs to be very finely ground to be effective\n* Long dry mixing time is needed to ensure very thorough mixing\n* Pozzolan cements are prone to corroding copper pipe\n\n===Pallets===\n* 3 or 4 make a compost bin or potato planter.\n* Rarely they're made into [[Fence|fencing]]\n* kids play house - they can build it\n* Sheds\n* Some people reuse the timber for lots of things\n\n===12mm & 18mm chipboard===\n* Loft flooring (12mm is for non habitable use only)\n* [[Shelves]], either long ones or small corner shelves.\n* Very narrow strips of [[Sheet Materials|chip]], [[Sheet Materials|ply]], wood & [[Sheet Materials|mdf]] can be used as [[Shelves|card shelves]] or spice shelves.

Open the chuck jaws, remove the screw down the centre, and the chuck unscrews.\n** Add an sds adaptor and you can use it in an sds drill.\n* Bearings often usable for projects.\n\n===Electrical accessories===\n* Re-use square pin accessories in outbuildings\n* Round pin sockets can be added to new lighting circuits to enable plugin lamps to be controlled by the lighting wall switch. However the appearance & reliability of new ones is much preferred.\n* Round pin socket systems & fusebox can be left in place and supplied from 12v or 24v and used to run small appliances, [[Lighting|lamps]] etc. Eliminates many [[wallwart]]s. 2 voltages may be fed down one 3 core cable, eg 6v & 12v.\n* Round pin sockets can be used for loudspeaker wiring, either 8 ohm or 100V line.\n\n===Paint===\n* Re-use small tins of grotty old (waterbased) colours by adding a little to white emulsion to make pastel colours.\n* Re-use disliked colours of [[Paint|emulsion]] by changing the tint with other coloured [[Paint|paint]], and adding white to lighten it.\n* Donate to local school for art and craft use\n* Dip tool handles in [[Paint|gloss paint]] to identify [[:Category:Tools|tools]] and [[Tool Theft|discourage theft]]\n* [[Papercrete]]\n* Make coloured mortar by adding emulsion to the [[Mortar Mixes|mortar mix]].\n\n===Weeds, leaves, clippings etc===\n* Apply to ground to feed plants & as mulch\n* grow a new hedge: stick tree/hedge clippings in ground, keep shaded and watered. 25% success rate is typical for 18\" hardwood cuttings, so plant sticks closely.\n* Grow a new plant border for free: stick lots of assorted clippings in ground, keep shaded and watered.\n* Nettle tops make nice soup if fresh growth\n* A pile of twigs & branches houses wildlife over winter, which eat lots of garden pests in the summer.\n\n===Paper===\n* Cardboard: weedkilling ground blankets\n* Cardboard, b&w newspaper: Compost heap if torn\n* Wallpaper, lining paper: kids art paper (use reverse of wallpaper)\n* All paper: [[Papercrete]]\n\n===Crockery===\n* same use as Broken tiles\n\n===Pipe===\n* Many things can be constructed from [[Make Things from PVC Pipe|plastic pipe]]. See [[Make Things from PVC Pipe]]\n* Metal pipe also makes various goods\n* Cut into short pieces (2-3\") and screw to wall as tool holder\n* Cut into short pieces and let the kids solv weld them together side by side to make a desk tidy\n* Large quantities of flexible pipe can make an effective [[Solar Thermal|solar preheater]] for very little.\n* Wacky [[brackets]]\n\n===Gravel===\n* Paths\n* On flower beds\n* Weight down planters with gravel in the base. Aids drainage & makes them harder to steal.\n\n===Sand===\n* Yellow sand: kid fun. Red sands tend to stain.\n* Add to heavy soils to improve porosity/drainage\n\n===Grinder discs===\n* Small worn down discs enable a [[Angle Grinder Discs|grinder]] to get into some places a full disc can't.\n* Hand grindstone\n* Dead Diamond Discs: Repair plates for damged timber\n\n===Expanded polystyrene===\n* [[Insulation]]\n* [[Papercrete]]\n* [[Mortar Mixes|Lightweight concrete]]\n\n===Silicone===\n* Make a mould of a small items, cast a few replicas in [[Mortar Mixes|cement mortar]] or plaster, build them into a new wall for decoration.\n\n===Expanding foam===\n* Make fake dog turds, kids love them. Just let some drop in one spot, don't move the nozzle around and it shapes itself the same way a real one does.\n\n===Breeze blocks===\n* Kids can carve them with a [[Saws|breadknife.]]\n* blocks + [[Sheet Materials|sheet wood]] = basic bed. Make sure its stable though.\n\n===Clinker===\n* Path surface\n* Path base\n* Add to [[Mortar Mixes|mortar]], crushed or whole\n* Washed clinker is used in plant cultivation\n\n===Ash===\n* Paths\n* Woodash is an unbalanced fertiliser when used in small amounts. A layer inches thick kills all plants.\n* Coal ash is a main ingredient in [[Mortar Mixes|black mortar]], but this is best only used to match existing pointing. [[Mortar Mixes|Black mortar]] is prone to premature failure sometimes, so is not recommended for general uses.\n\n===Glass===\n* Secondary glazing\n* [[Solar Thermal|Solar panel]] - a huge range of types and designs exist, see [http://www.Builditsolar.com]\n* Shed window\n* Small toughened glass sheet: hygienic chopping board\n* Sparkly concrete surface for moulded concrete: break glass into small bits (mixer & brick), place some in mould & pour in [[Mortar Mixes|concrete.]]\n* use as [[Mortar Mixes|concrete aggregate]]\n* Glass cullet is even being used as garden mulch now. Tumble it to remove sharpness.\n\n===Timber===\n* A lot of substandard and damaged [[:Category:Wood|timber]] can be used in [[Partition Wall|stud walls.]]\n* Small pieces are usable as noggings\n* Rarely it can be worth [[Adhesive|gluing]] bits together to use for [[Partition Wall|stud wall]] uprights.\n* Wood strips 4mm or more thick can be used as very light [[shelves]].\n* Large quantities of short pieces can make a shed or playpen using a lattice or geodesic dome construction. A good kids project.\n* See Ash\n\n===Clay & Clay Subsoil===\n* Use in making [[Making Concrete Blocks|concrete blocks]]\n* [[Papercrete]]\n* Adobe building blocks\n* Cob walls.\n* Cast earth\n* If you roll a sausage with it and can dangle the end of the sausage over the edge of your hand, and it bends over without breaking off, its probably good enough for pottery. Offer such clay to someone that uses clay, eg a school.\n* Clay subsoil also makes clay plaster, which is a usable plastering material.\n* Make a mud oven in the garden. (Cooks & looks better than a barbecue.)\n* Small clay goods may be baked by putting them in a coal fire once completely dry.\n\n===Insulation===\n* Assorted [[insulation]] scraps can be packed round the hot water cylinder to reduce summer heat loss\n* Don't bury the cable feeding an immersion heater in insulation\n* Scraps of polystyrene (eg clean food containers), bubblewrap, packaging peanuts and scrap cloth can be included\n\n==Other Uses==\n===Kids===\n* Kids are not usually recommended for re-use, but they can use many scrap building materials for play. They can learn to tile, make [[Mortar Mixes|cement]], plaster or breeze block ornaments, wendy houses, tree houses and so on. Some especially like creating mosaics.\n* A small minority of kids have good concrete reinforcing properties.\n\n===Freecycle===\n* Offer leftovers on Freecycle, Craigslist etc. Its surprising what people will pick up.\n** [http://www.freecycle.org freecycle] [http://uk.freecycle.org/ freecycle] [http://www.freecyclefinder.org/ freecycle finder]\n** [http://www.craigslist.org/ craigslist]\n** [http://freesharing.org/england.php freesharing]\n\n===Firewood===\n* Sometimes people will take wood away free for burning.\n\n===Concrete blocks===\nMany materials can be included in the mortar mix for blocks. Many of them affect the final block properties, and the additions should be suitable for the job the blocks will be used for.\n\nAlso almost any non-expanding material can be put into the middle of [[Making Concrete Blocks|concrete blocks]] to [[Mortar Mixes|reduce cement use]] and dispose of it free.\n\nUsable materials include:\n* glass (preferably broken into cullet)\n* plaster (preferably powdered)\n* mashed or shredded paper\n* bricks (broken up or dust)\n* tiles (broken up)\n* crockery (broken up)\n* water based paints, eg emulsion\n* broken up hard plastics (thermoset)\n* gravel & stone waste\n* angle grinder grit discs (not diamond or TC)\n* breeze blocks (broken up)\n* clinker\n* ash (but not coal ash, it reduces block life expectancy)\n* rubble (broken up)\n* silt\n* clay, if poorer handling properties are acceptable\n* gone off cement can be added as an inert filler, in small amounts\n* lime\n* chalk (broken up)\n* sawdust\n* rocks (for foundations)\n\n==See Also==\n* [[Disposal Methods]]\n* [[Special:Allpages|Wiki Contents]]\n* [[Special:Categories|Wiki Topic Categories]]\n\n\n[[Category:Garbage]]\n[[Category:Save Money]]\n[[Category:Mortar]]"

                        "*": "==Types==\n===Nickel===\n;[[NiCd]] \n:Low capacity, slow charge rate and toxic cadmium. A typical AA Nicad gives 0.45Ah from a 15hr charge. 1.2v per cell.\n\n;[[NiMH battery|NiMh]]\n:AA NiMH typically 0.8Ah - 2.8Ah, charge rates from 5hrs to 15 minutes. 1.2v. New NiMH are mostly low self discharge (LSD), older ones steadily discharged themselves. LSD NiMH are usually labelled as ready-charged, something that's not practical with earlier NiMH.\n\n;NiFe\n:[[History|Historic]] forerunner of NiCd. Seldom seen, but one manufacturer of industrial sized cells does exist. Extremely long lived, some made in the 1920s still work. Most can be rejuvenated by replacing the electrolyte. Initial cost higher than lead acid, but lifetime far longer.\n\n;Ni-Zn\n:Nickel zinc cells have a high 1.6-1.8v terminal voltage. The low number of recharge cycles has long been a problem, but 500 cycle cells are available now. Lower capacity than NiMH. Unpopular as of 2013, they are currently only sold by Maplin, and only available in sub-C, AA & AAA. [http://en.wikipedia.org/wiki/Nickel%E2%80%93zinc_battery Wikipedia]\n\n===Lead acid===\n;[[Lead acid]]\n:Large, heavy, lowest cost per capacity. Mainly used in [[car]]s. [[Acid]] spills out if tipped. Starting batteries (as used in cars) don't last long when discharged 50% or more repeatedly, its then important to choose deep discharge or leisure batteries.\n\n;[[Lead acid|Sealed lead acid]]\n:SLA are spillproof variants of [[lead acid]]s. Mainly used in alarms, golf & mobility buggies, UPS, etc.\n\n===Lithium===\n;Lithium ion\n:Li-ion cells store more [[energy]] than the same size NiMH, and charge faster, hence their main use in [[Computing|laptops]]. Correct charging is essential, or they catch [[fire]].\n\nThere are also non-rechargeable lithium batteries.\n\n===Alkaline===\n;Rechargeable alkaline\n:A rechargeable variant of [[Alkaline battery|alkaline]]. Not in general use in UK, can be bought from abroad. They don't last as well as NiMh and NiCd, and have short lives if deep discharged. They provide 1.4v per cell when recharged, useful for [[appliance]]s that don't play well with NiCd and NiMH. [http://en.wikipedia.org/wiki/Rechargeable_alkaline_battery Wikipedia article]\n\n==Are rechargeables worth it?==\nGood AA rechargeables ones now give similar capacity to [[Alkaline battery|alkaline]], around 2.8Ah. At \u00a31.50 a cell lasting 500 charges that's 0.3p per charge. Alkaline AAs at 17p each are thus 56x the cost.\n\n[[Zinc carbon]]s are much cheaper per [[battery]], but give even less capacity per cost.\n\nThe cost of the recharging [[electricity]] is trivial. A 2.5Ah 1.2v cell holds 3 watthours, or 0.003 kWh. Allowing for inefficiencies, 0.005kWh costs 0.005x13p = 0.065p. You can recharge 15 for a penny.\n* Alkaline cost: 17p each\n* Rechargeable cost plus electricity: 0.365p per cycle\n\nWhere capacity isn't so important, [[cheap]] rechargeables at half the price typically give around 1/3 the capacity.\n\n\n==When they're not as good==\nDiscussion of the apps where alkaline are better is [https://groups.google.com/forum/?fromgroups#!topic/uk.d-i-y/2-fEtNS-DAQ here]\n\n\n==Cordless tools==\nNiCd 1.3-2 Ah sub-C cells are most common. Energy capacity = voltage x Amphours. The quality of nicads varies widely, affecting how long they last in trade use.\n\nLi-ion powered [[tools]] cost more, and are less likely to come with more than one battery pack. The advantage is faster recharging.\n\nSupercapacitor powered tools are rarely seen. These have low capacity, but extremely fast recharge. The number of charge cycles is not limited as battery chemistries are. [http://www.ohgizmo.com/2007/10/01/coleman-flashcell-cordless-screwdriver-recharges-in-just-90-seconds/ ohgizmo]\n\n==Battery failure==\nCordless [[tool]] NiCd battery packs can be recelled, but its too often not worthwhile. Recelling with budget cells may be cheaper, but how long they last in non-diy use is another matter.\n\nNiCd and NiMH cells that won't hold charge can in theory be zapped with a moment of high charge current to burn out the shorting dendrites and make them work, but zapped cells quickly re-short.\n\nLi-ion cells have limited life even when not used. A li-ion battery that's little used lasts longest if stored half charged in a [[Fridge freezer|freezer]], sealed in a bag to keep it dry. Defrost before use, eat before sell by.\n\nA seldom seen option is to run a 12v - 18v tool on a lead acid battery on a short lead. It does at least provide many times the battery capacity. Current draw is upto 20A or 30A, so the [[flex]] should be rated to at least 5A (30A wire would only be needed for continuous operation.)\n\nLead acids can sometimes be repaired by replacing the electrolyte, but handling toxic lead compounds and [[acid]] for the cost of a new battery isn't normally worthwhile.\n\n==See also==\n[http://en.wikipedia.org/wiki/Rechargeable_battery Wikipedia]\n\n\n[[Category:Batteries]]"
