Li2e most t!ings e try to classify one ay or t!e ot!er3 t!ere tend to be some e"ceptions or outliers. Apples3 for e"ample3 ripen after being pic2ed and increase in not just seetness but also get softer over time. Most people prefer apples under ripe @since t!e varieties generally eaten uncoo2ed tend to be fairly seet rig!t off t!e treeB and do not prefer t!em at full ripeness due to !o soft @and mealyB t!e fles! becomes. @%ecause apples do ripen after !arvesting and e donXt often allo t!em to reac! full ripeness3 if youXve got an apple in your !ouse3 itXs probably in t!e process of ripening and t!erefore outgassing carbon dio"ide and et!ylene. $!e latter gas ( for reasons not yet fully understood ( ill trigger and speed up ripening processes in ot!er fruits !ic! can be ripened after pic2ing ( see c!art beloB. Anot!er e"ample is t!e pineapple @a fruit t!at doesnXt ripen after !arvestB !ic! does c!ange color after being pic2ed but does not get seeter or develop a stronger aroma. 9or t!is reason3 t!ey s!ould be selected not by !o golden t!e s2in is but by !o fragrant it is. Since fruits !ic! ripen release et!ylene gas3 t!ey s!ould not be stored it! or near vegetables. $!e et!ylene ill cause most vegetables to spoil faster. @Many vegetables can be !eat treated ( by blanc!ing in boiling ater for a minute or to ( !ic! deactivates t!e en?ymes !ic! cause ilting and spoilage. It is possible t!at !eat treating could prevent spoilage from et!ylene e"posure3 but I !ave not found any documentation of t!is and !ave not performed t!e e"periment yet.B Conventional isdom states t!at fruits !ic! are ripened on t!e plant ill be superior to t!ose pic2ed early @and possibly ripened later if it is one of t!ose luc2y fruits t!at can continue to ripenB. $!ere is muc! trut! in t!is3 but again t!ere are some interesting e"ceptions. $!e first is t!e avocado !ic! does not ripen on t!e tree at all. $!is is one fruit !ic! !as to be pic2ed @or fall off t!e treeB to begin ripening. I as surprised to learn during my researc! t!at Modernist Cuisine claims pears also do not ripen on t!e tree. $!is is not tec!nically true as pears do ripen on t!e tree but many varieties do not taste good !en tree(ripened it! particular complaints regarding off(flavors. ears are one of t!e fe fruits !ic! are best ripened off t!e tree. %ananas are anot!er interesting case as it is t!e ultimate e"ample of ripening after !arvest ( bananas improve in every aspect @seetness3 color3 aroma3 and te"tureB dramatically !en ripened at !ome and3 by all accounts3 is as good as !en plant(ripened. 9ruits t!at ripen after being pic2ed can !ave t!eir ripening processes accelerated easily in to ays: !eat and et!ylene. 'eeping fruits in a arm environment ill ripen t!e fruit by accelerating t!e activity of t!e ripening en?ymes. $!is process speeds up until t!e temperature rises past t!at at !ic! t!e en?ymes remain intact @!ic! is loer for fruits from colder eat!er regions and !ig!er in tropical fruitsB. $!is can also increase t!e rate of spoilage as surface bacteria and microorganisms ill generally t!rive in arm temperatures up to t!e deactivation temperature of t!e en?ymes. 7as!ing t!e fruit it! a fruit as! is advisable before attempting to !eat ripen it. #t!ylene gas ripening is probably easier since all it ta2es is an et!ylene producer @t!e fruit itself ill or23 but an apple is even betterB. Simply place t!e fruits in a paper bag it! t!e top folded over. $!is creates an environment !ic! allos some airflo but ill increase t!e concentration of et!ylene gas around t!e fruit. 7!en fruits !ic! ill ripen after !arvest are e"posed to a !ig! et!ylene concentration3 ripening is promoted.

-Liquid Waste-
Liquid waste can contaminate land and pollute waters. It can be defined as such fluids as wastewater, fats, oils or grease (FOG), used oil, and hazardous household liquids, to name a few. he erritor!"s landfills and transfer station do not accept liquid waste of an! t!pe. Liquid waste can be di#ided into three main streams$ sewerage, trade waste and hazardous liquid waste. %ewage is a water&carried waste, in solution or suspension, that is intended to be remo#ed from a communit!. 'lso nown as domestic or municipal wastewater, it is characterized b! #olume or rate of flow, ph!sical condition, chemical and toic constituents, and its bacteriologic status (which organisms it contains and in what quantities). It consists mostl! of gre!water (from sins, tubs, showers, dishwashers, and clothes washers), blacwater (the water used to flush toilets, combined with the human waste that it flushes awa!)* soaps and detergents* and toilet paper (less so in regions where bidets are widel! used instead of paper). +hether it also contains surface runoff depends on the design of sewer s!stem.rade waste means the liquid waste generated b! an! industr!, business, trade or manufacturing process. It also includes wastewater contaminated with substances lie grease, oils, solids and chemicals.azardous liquid waste is a waste with properties that mae it potentiall! dangerous or harmful to human health or the en#ironment. he uni#erse of hazardous wastes is large and di#erse.azardous liquid waste is considered toic, chemicall! reacti#e, flammable or corrosi#e.
