🔋 ShaktiLoop
Deposit-return EPR diverts Bangladesh's e-rickshaw batteries from toxic backyard smelters
How ShaktiLoop closes the loop
Spent battery → Safe collection → Formal recycling → Recovered lead → New batteries
A clean vehicle, a poisonous battery
3–4 million e-rickshaws are green to ride — but their lead-acid batteries are recycled in open pits, the country's largest single source of lead poisoning.
Out-bid the fire-pit, recycle safely
Pay battery shops and collection agents a fair, traceable price — above the informal smelter — to divert every spent pack into licensed safe recycling, and close the loop with producer-responsibility (EPR) funding + enforcement. The circular sibling of LeadSafe: LeadSafe detects the lead; ShaktiLoop cuts its #1 source.
Stop the buy-back war — deposit-return flips it
Per battery set (~125 kg of lead). Red-team correction: out-bidding 1,100 informal smelters on a spot price is a war you can't win (lead-alone −3k/battery; a rational smelter just re-bids). The redesign stops paying a buy-back entirely:
How it makes money — and what it needs to close
Needs a deposit-return scheme or EPR mandate (Dept of Environment) so formal recycling out-bids backyard smelters, plus a B2B fleet contract. Without the mandate, informal collectors out-bid you. PAYG nodes cut the CAPEX.
deposit-return + EPR + B2B fleet
recovered lead → · EPR fees · deposit-return handling · health/carbon
recovered lead value (deposit-return kills the buy-back cost) + EPR
importers must fund compliant takeback; the deposit guarantees the stream
−3k → +16.5k/battery (PAYG nodes cut CAPEX)
Flips from −3k to +16.5k/battery once PAYG nodes cut the CAPEX — but only with a deposit-return/EPR mandate so formal recycling out-bids backyard smelters.

Deposit-return EPR diverts Bangladesh's e-rickshaw batteries from toxic backyard smelters
Formal recycling reaches ~99% recovery (US EPA) under EPR
167,000 t lead waste/yr from e-rickshaws · ~3.6% of GDP
The situation in Bangladesh
Bangladesh now runs an estimated 3–4 million electric three-wheelers that move over 112 million people a day, and their oversized lead-acid batteries generate roughly 167,000 metric tons of lead waste each year 2. Much of that flows to more than 1,100 informal and illegal recycling operations, where batteries are broken open and melted in open-air smelters near homes, schools and farms with little or no environmental control 2. The toll is staggering: about two-thirds of Bangladeshi children (roughly 36 million) have elevated blood lead levels, lead pollution erases an estimated 20 million IQ points in children under five, and the damage costs the country around US$10,897 million, about 3.6% of GDP 25. Globally this same pattern of informal battery recycling is a leading source of childhood lead poisoning, and Bangladesh ranks fourth in the world for the number of children affected 16.
Our pitch
ShaktiLoop closes the loop with a deposit-return scheme backed by extended producer responsibility: buyers pay a refundable deposit on each battery and reclaim it only by returning the spent unit to a certified collector, so end-of-life batteries are routed to safe formal recyclers instead of backyard smelters 3. The wedge is economic, not merely regulatory — recovered lead carries real market value for manufacturers, and formal lead-acid recycling can reach recovery rates near 99% with new batteries made from over 80% recycled material, giving certified recyclers a revenue base to out-bid informal operators 3. The hard lesson from India is that mandates alone fail when informal recyclers still capture roughly 80% of battery waste, so ShaktiLoop pairs the deposit incentive with formal collection logistics that integrate or out-compete informal collectors at the point of return 7. Because childhood lead exposure costs lower- and middle-income countries an estimated US$977 billion a year in lost productivity, even a partial shift from informal to formal recycling carries enormous health and economic upside for Bangladesh 4.
Built so the operator never fails
HelperChain doesn't hand out a loan and walk away. Every operator gets the full rail — inputs, training, finance, supervision, and a guaranteed buy-back of what they produce. We carry the risk so an ordinary person can succeed.
The tools, inputs and hands-on training to start — turning spent battery into a working operation. No prior capital or expertise required.
Pay-as-you-go, riba-free finance makes a poor person a funded operator — with no debt if a cycle fails. The network carries the downside, not the operator.
Ongoing follow-up and quality assurance — the factor peer-reviewed evidence shows decides whether ventures survive (p<0.001). The operator is never left alone.
We commit to purchase the output at a fair, pre-agreed price — so there is always a market. The operator just produces; we guarantee the offtake. This is what removes the fear of failure.
A thin margin funds the next operator — so help compounds and the network grows stronger with every person it lifts.
