Research objectives of the UNITE mobility in RTU

1.
Analyse

the

reverse

supply

chain

of

the

electronics

sector

in

Latvia
.


2.
Identify

potential

areas

of

improvement
.



3.
Study

the

relevant

decisions

in

the

context

of

a

closed
-
loop

supply

approach

to

develop

the

reference

model
.


4.
Recognise

opportunities

for

the

Latvian

economy

and

companies
.

collected

in

The

agreement

reached

on

14
/

/
2011

by

the

EU

Council

foresees

that

member

states

must

annually

collect

45
%

of

the

average

weight

of

electrical

and

electronic

equipment

placed

on

their

national

markets
.

This

would

take

effect

four

years

after

the

entry

into

force

of

the

revised

law
.

Four

years

later,

member

states

are

to

achieve

a

65
%

collection

rate
.


Latvia

may

attain

a

collection

rate

of

40
-
45
%

by

2016

and

must

achieve

the

full

collection

targets

by

2022

at

the

latest
.
