Avui hem fet un treball d’investigaci\u00f3 a l’aula, perqu\u00e8 hem descobert com s\u00f3n per dins els brics de llet. Aquests envasos, que fem servir di\u00e0riament, els llencem al seu contenidor corresponent: el groc. Per\u00f2, a ull nu, sembla que estan fets de cart\u00f3. Aix\u00ed que sorgeixen moltes preguntes:<\/p>\n

\u2014 Per qu\u00e8 no es reciclen al contenidor blau?<\/p>\n

\u2014 Estan fets de cart\u00f3?<\/p>\n

\u2014 De qu\u00e8 estan fets aquests brics?<\/p>\n

\u2014 Quantes capes tenen?<\/p>\n

\u2014 Tot \u00e9s pl\u00e0stic?<\/p>\n

\u2014 Com s\u00f3n per dins?<\/p>\n

Llavors comencem a estudiar la composici\u00f3 d’aquests brics i descobrim 3 materials: cart\u00f3, pl\u00e0stic i alumini. Aquests materials estan distribu\u00efts en 6 capes: pl\u00e0stic, cart\u00f3, pl\u00e0stic, alumini, pl\u00e0stic i pl\u00e0stic. Els brics s\u00f3n un residu que genera confusi\u00f3, ja que si b\u00e9 un dels seus components \u00e9s el cart\u00f3, tamb\u00e9 estan formats per capes de metall (alumini) i de pl\u00e0stic (per recobrir el cart\u00f3). De fet, moltes persones fan servir expressions com \u201ccart\u00f3 de llet\u201d. Per\u00f2 ni el nom ni l\u2019aspecte no ens han de confondre: els brics s\u00f3n envasos lleugers i, per tant, s\u2019han de llen\u00e7ar al contenidor groc.<\/p>\n
